Ryan Carney and his colleagues at Brown University released a scientific paper on the feathers of the Archaeopteryx today. Carney celebrated by having an Archaeopteryx feather tattooed on his arm, thereby gaining himself an entry in Carl Zimmer’s science tattoo collection. But what about the Archaeopteryx?
The first fossil of Archaeopteryx was a single feather–the one that Carney has turned into a tattoo. It was discovered in 1861 in a limestone quarry near the town of Solnhofen and brought to Hermann von Meyer, one of Germany’s leading paleontologists at the time. As scientists would later determine, this exceptional feather was 145 million years old. Despite its antiquity, the feather looked much like the feathers on the wings of living birds.
The fossil was so extraordinary that Von Meyer wondered if some forger had etched it. After all, Solnhofen limestone was prized for making finely detailed lithographic prints. But then von Meyer compared the slab and the counterslab and found them to be identical.
Now 150 years later, we know a lot more about the Archaeopteryx and how it fits in the evolution of dinosaurs to birds. Read how many of these discoveries came about at The Loom. Link
Megalonyx jeffersonii
Fossils rarely do scientists the courtesy of showing up intact, so putting them together is like solving a jigsaw puzzle. A tough one. Without a picture on the box to go by. It’s no wonder a few old bones have made some of the world’s smartest scientists look so stupid.
1. All the President’s Sloths
In decades past, American presidents apparently had hobbies other than playing golf and eating at McDonald’s. Thomas Jefferson, for one, was an avid paleontologist. As early as the 1790s (before it was cool), he kept an impressive fossil collection at his home in Monticello. So when a group of confused miners came upon some unidentifiable bones in a West Virginia cave, they sent them to Jefferson. Judging from the long limbs and large claws, the president suspected they belonged to a giant cat “as preeminent over the lion in size as the mammoth is over the elephant” and that the animal might still exist somewhere in the unexplored West.
Jefferson got the size right. The description? Not so much. The animal he named Megalonyx (giant claw) was actually one of the giant ground sloths that very slowly roamed America during the last ice age. And while Jefferson later agreed with this alternative diagnosis, his error wasn’t a complete waste. The Megalonyx marked one of the first important fossil finds in the United States, and it prompted the first and second scientific papers on fossils published in North America. In honor of the president’s contribution, the sloth’s name was later formalized to Megalonyx jeffersonii.
2. A Bone-headed Approach
To this day, the Brontosaurus remains one of the most popular and recognizable dinosaurs in history – an impressive feat for an animal that never existed. The confusion started in 1879, when collectors working in Wyoming for paleontologist Othniel Charles Marsh found two nearly complete – yet headless – sauropod dinosaur skeletons. Wanting to display them, Marsh fitted one specimen with a skull found nearby, and the other with a skull he found in Colorado. Voila! – the Brontosaurus was born.

Unfortunately for Marsh, the skeletons were later exposed as adult specimens of a dinosaur already discovered, the Apatosaurus. The error was formally corrected in 1903 by Elmer Riggs of Chicago’s Field Museum, and scientific papers haven’t called the animal Brontosaurus since. Seventy more years passed before researchers determined that the skulls Marsh borrowed really belonged to the Camarasaurus, a discovery of his archrival, Edward Drinker Cope. Pop culture, however, missed the memo altogether.
3. Getting Your Head Screwed on Right
Paleontology’s version of the Hatfields and the McCoys, Marsh and Cope had a nasty and long-running professional rivalry. Although they’d actually started out as friends (with each even naming a discovery after the other), by 1870 their relationship had taken a turn for the worse. A year earlier, Cope had assembled a skeleton of the sea reptile called Elasmosaurus. However, in his rush to publish his discovery, he placed the head on the wrong end, giving everyone the impression that the animal had a very long tail instead of a very long neck. Marsh poured ample salt in that wound by making fun of Cope’s error in print (suggesting he rename the animal “twisted lizard”) and constantly ridiculing it at parties and exhibitions. Given the stakes, he might as well have slapped Cope across the face with a glove and insulted his mother. As it was, all Cope could do was try and buy up all the published examples of his posterior-backwards construction.
Incorrect image of Elasmosaurus published by Cope.
The feud only grew from there. The two men fought over allegations that, on a tour of Cope’s digging operations in New Jersey, Marsh bribed collectors to send key fossils to him. And in 1877, a part-time collector in Utah incited a whole new string of cutthroat arguing by trying to sell bones from his site to both of them. Other feud highlights included a series of snippy “he said, he said” pieces in the New York Herald and the time the Smithsonian confiscated much of Marsh’s fossil collection after Cope accused him of misusing tax dollars to hoard fossils for himself.

Of all invertebrates, the octopus is considered the most intelligent, and sadly, rather underrated. They’ve been caught on video wrestling sharks to death like sea-dwelling honey badgers, using tools and opening twist-cap bottles. And according to at least one paleontologist, their ancestors may have been bigger, smarter, scarier and perhaps even a bit artistic.
The Triassic World
During the Triassic Period, a creature we call Ichthyosaur swam the seas, chowing down on whatever it wanted–it was the size of a school bus and had a mouthful of jagged teeth, and until Monday, paleontologists assumed it sat at the top of its watery food chain. But a stash of nine interestingly arranged, fossilized icthyosaur bodies discovered in Nevada have long confounded researchers, who haven’t been able to determine how they died. Formerly, it was believed the seas were shallow in that location and the giant proto-whales fell victim to an algae bloom. But evidence from the surrounding rocks indicate the seas were still deep at the time of their demise, leaving science with something of a mystery.
That’s where Mount Holyoke College paleontologist Mark McMenamin comes in. “Charles Camp puzzled over these fossils in the 1950s,” said McMenamin. “In his papers he keeps referring to how peculiar this site is. We agree, it is peculiar.” See, the bones of these ichthyosaurs are etched differently from one another, indicating that they didn’t die at the same time. But since they’re all buried together, something interesting had to have happened. And McMenamin thinks that “something” is the work of kraken.
Deliberate Burial
McMenamin believes that the midden-building and predation behaviors observed in modern octopuses–specifically that of the famous Shark vs. Octopus video, wherein an unassuming dog shark gets totally pwned by a seemingly mild-mannered cephalopod–support the theory that gargantuan prehistoric kraken were terrorizing the ichthyosaur population, “either drowning them or breaking their necks.” Suspiciously twisted necks and many broken ribs from the ichthyosaur dig seem to support the idea, as fantastical as it is. But weirdest of all is how the bones came to be buried together, and why their arrangement seems bizarre: “I think that these things were captured by the kraken and taken to the midden and the cephalopod would take them apart,” and rearrange them into what McMenamin believes is “the earliest known self portrait.”
In the fossil bed, some of the shonisaur vertebral disks are arranged in curious linear patterns with almost geometric regularity, McMenamin explained.The proposed Triassic kraken, which could have been the most intelligent invertebrate ever, arranged the vertebral discs in double line patterns, with individual pieces nesting in a fitted fashion as if they were part of a puzzle.
To illustrate, the bones are arranged like this:
That’s not even a little bit creepy.
Or is it Pareidolia?
Soft-bodied animals, by virtue of definition, have nothing to leave in the fossil layer, so McMenamin’s tentacled beast will likely never turn up even if it did exist. And this presents something of a problem for the theory, since many researchers are “highly skeptical” of his “evidence.” Roger Hanlon, a marine biologist at the Marine Biological laboratory in Woods Hole, Massachusetts, says,”There’s nothing in the scientific literature that suggests that modern-day cephalopods do anything like this.” And according to Dr. Hans-Dieter Sues, curator of vertebrate paleontology at the Smithsonian’s National Museum of Natural History, the Nevada site “essentially represents a mass burial ground for ichthyosaurs in a shallow sea.” Speaking to Christian Science Monitor, Dr. Thomas Holtz Jr. of the University of Maryland declares that McMenamin’s approach to understanding the ichthyosaur peculiarities “is too many steps away from the evidence to call it science.”
But that doesn’t mean that McMenamin is universally scorned: science writers and kraken enthusiasts are rooting for McMenamin and his Triassic tentacled leviathan. Rebecca Boyle of PopSci is sympathetic, hypothesizing that “the hypothetical kraken was just lonely, and, unable to clone itself [as some modern jellyfish can], it made an artistic rendering of an imaginary friend? It seems possible, although maybe less possible [than] the imagined kraken.” But if moral support is what McMenamin needs, Cyriaque Lamar at io9 has got it in spades: ”[T]he possibility of finding that which is essentially a gargantuan mollusk’s macaroni illustration? That’s the kind of glorious crazy you hope is reality.”
What do you think, guys? Is McMenamin’s idea a little too crack-pot to hold water, or is there maybe something to this whole self-expressive kraken thing?

This fossilized Polycotylus latippinus, a carnivorous marine reptile that lived 78 million years ago, contains a smaller, less developed skeleton inside of her. Scientists are therefore speculating that this creature did not lay eggs like other dinosaurs, but gave birth to live young. If true, then this dinosaur may have exhibited maternal care behavior similar to modern marine mammals, such as dolphins. This fossil is on public display at the Natural History Museum of Los Angeles, so if you live in that area, you can get a close look for yourself.

Have you ever wanted your own dinosaur and a man-servant? If you do, and you happen to own an extra house in Vancouver, today just might be your lucky day. A man in Vancouver is offering up his services as a pet dinosaur (the species is your choice) and a maid/nanny for one full year in exchange for his own Vancouver home at the end of his servitude. A few choice excerpts:
Do you own more than one property? Do you have so many rental homes with no mortgage payments, yet you still feel unfulfilled? Tired of your illegal tenants whining that there are rats in the walls? Have you always wanted your own dinosaur? Now is your chance my friend.
In exchange for one of your properties, I will be your personal dinosaur for one year. I will be at your beck and call, 24 hours a day, wearing a dinosaur costume. The type of dinosaur is negotiable. I can babysit your children (references upon request), scare the mailman, wash dishes, entertain and impress your guests, and much more.

An engraved bone, believed to be from a mastodon, giant sloth or mammoth, may be the oldest example of primitive art ever found in the Americas. The carved bone features the depiction of an ancient mammoth, and was discovered by an amateur fossil hunter in Florida, in an area near Vero Beach where other mammoth bones have recently been found. The archaeological team working on carbon dating the bone feel that it is at least 13,000 years old, and that the etching must be at least that old as well.
What was the average body temperature of the Dinosaurs? Researchers are now able to answer that question by studying their teeth and the results may be surprising.
The new technique measures the concentration of clumps of carbon-13 and oxygen-18 within bioapatite, a mineral in the teeth. The amount these two isotopes bond together depends on the temperature of the host animal, with colder body temperatures leading towards more bonding.
First they blew your mind when they told you Pluto isn’t actually a planet, then they told you that not only is Atlantis real, it’s been sitting in the bottom of some mudflats in Spain for a few thousand years. It seems history and science keep changing right in front of our eyes and pretty soon, nothing we learned in school will be true any more. Well, if you can’t deal with change, then you aren’t going to like these four things you learned in school are actually completely bogus.
If you learned one thing about Egypt in school, it was that the pyramids are marvels of ancient technology…and that they were built by slaves. There are movies based around slaves working on the pyramids and every one has seen at least half a dozen pictures of the poor workers straining under the hot sun as their cruel masters wait, whip in hand, for someone to slack off.
But working on the pyramids might not have been so bad after all. While it was still hard work to construct the massive monuments, recent research has shown that the workers were more likely skilled masons who had the right to leave whenever they wanted. Evidence to back this claim is supported in the fact that the workers had their own tombs right beside the pyramids. Egyptologists point out that someone that low on the social ladder would never have been buried so close to the pharaohs.

Ok, maybe not everything you learned about dinos back in school was wrong, but a lot of it sure was. For one thing, there is no brontosaurus. Yeah, that giant lumbering monster we all learned about in grade school was actually an apatosaurus with the head of a camarasaurus. The worst thing about this inaccuracy is that it was discovered over a century ago, but up until recently, everyone (including a lot of elementary school teachers) still insisted on calling apatosauruses brontosauruses.
I guess one mislabeled dino isn’t that big of a deal…but the incorrect visual representation of just about every dinosaur imaginable is. By now, you’ve probably heard that many dinosaurs probably had feathers, a huge change for those of us who grew up thinking about giant lizards roaming the prehistoric plains. But even those that probably didn’t look like giant birds still looked way cooler and more versatile than the oversized iguanas popularly imagined. These days, we even know what color some dinosaurs were, and they are a far call from the multitude of green shades we once imagined. If you really want to know just how different dinosaurs were compared to what we were taught, check out this great article on Listverse, about the Top 10 Dinosaurs That Aren’t What They Were.

If you learned chemistry or biology in high school, you were probably taught that there are six chemical elements known as the “building blocks of life.” They are carbon, hydrogen, oxygen, nitrogen, sulfur and phosphorus. These components make up the chemical composition of DNA and without them, life isn’t possible…or at least, we thought it wasn’t possible.
Last year, scientists discovered a bacteria species living in a salt lake in California that was missing one of the building blocks of life, phosphorus, and instead had arsenic in its place. For some people, this might not seem like such a huge deal, particularly considering that arsenic is very close to phosphorus in its physical and chemical properties, but it’s a huge deal to scientists who suddenly saw a massive expansion in the scope of potential living things. It really makes a difference in intergalactic research, since the discovery opens up whole new planets as potential life-supporting ecosystems.

Maybe this wasn’t the case for all of you, but when I was in school, the teachers seemed overly fascinated with telling us how much better humans are than other animals. They’d tell the class, “we’re the only animals who have complex emotions,” “no other animal is self-aware like we are,” “humans are the only creatures who use tools,” “we are the only species to communicate through complex language,” etc. I don’t know why they felt our fragile homo sapien egos were so threatened by other creatures, but I always thought that was a little strange. As it turns out, it was completely incorrect too.
Recent studies show that elephants mourn the loss of their companions and many animals, particularly dogs (who have evolved in the companionship of humans), have far more complex emotions than scientists had ever imagined. And chimps don’t just have emotions; they also are self-aware enough to understand how their own actions will affect those around them.
Well, we still have our intelligence to set us apart from the beasts right? Not so quick you homo sapien- supremacists. Actually, there are a lot of intelligent animals out there, many of which use tools and converse amongst themselves. Chimps have used spears to hunt for thousands of years, octopuses use coconut shells as both camouflage and as protection, and dolphins use sponges to help uncover fish that are hiding in the sand.
As for language, bees have an incredibly complex language system allowing them to communicate what type of flower is located in a given place and how to get to that location. Monkeys not only communicate with one another vocally, but they even understand grammar rules. In fact, in some ways, animals are actually ahead of us in the language game. While humans cannot yet speak the language of any other animals, primates can be taught sign language so they can communicate with us in our own language.

If you haven’t studied dinosaurs since you were an elementary school student, you have some catching up to do! As paleontologists find more and different fossils, our body of knowledge about the prehistoric reptiles has changed. Take the Stegosaurus, for example. What we thought we knew just a few years ago is different from what we think we now know.
Fossil footprints and detailed studies of its anatomy have proven that Stegosaurus didn’t drag its tail on the mud, but actually walked erect, like an elephant, with its tail held horizontally, parallel to the ground. Its back wasn’t as arched as they had us believe, and the neck was not carried horizontally as usually depicted, but upright, like a bird’s.
Also, the tail spike cluster (known among paleontologists as the “thagomizer”) didn’t actually point upwards, but sideways. This made the tail a much deadlier and more efficient weapon; to stab an attacking predator, Stegosaurus only had to swing its tail horizontally; punctures matching the Stegosaurus’ tail spikes have been found in the bones of predatory dinosaurs from the same age and place, proving once and for all that Stegosaurus wasn’t any less dangerous than the ankylosaurs that would evolve later.
And that’s just the first of ten dinosaurs we once thought we knew. Link -via the Presurfer

But the scientists mean it as a compliment, not an insult. The brontomerus had exceptionally large leg muscles:
It could have given other animals a hefty kick, say its discoverers.
It seems most likely to us that what this is about is being able to deliver a strong kick”
“If predators came after it, it would have been able to boot them out of the way,” said Dr Mike Taylor, from University College London, UK.
The team has named its dinosaur Brontomerus mcintoshi – from the Greek “bronto”, meaning “thunder”; and “merós”, meaning “thigh”.
The fossilised bones of two specimens – an adult and a juvenile – have been dated to be about 110 million years old.
Suggestion: playfully address your wife and/or girlfriend as “thunder thighs”. Explain that you mean it in a good way, particularly that they give the ability to kick hard.

They must have done something to reproduce, considering they roamed the earth for millions of years. Yet they died out for one reason or another. And some dinosaurs, like the stegosaurus, were covered in armor and spikes, which doesn’t lead one to think of intimacy.
Figuring out how Stegosaurus even could have mated is a prickly subject. Females were just as well-armored as males, and it is unlikely that males mounted the females from the back. A different technique was necessary. Perhaps they angled so that they faced belly to belly, some have guessed, or maybe, as suggested by Timothy Isles in a recent paper, males faced away from standing females and backed up (a rather tricky maneuver!). The simplest technique yet proposed is that the female lay down on her side and the male approached standing up, thereby avoiding all those plates and spikes. However the Stegosaurus pair accomplished the feat, though, it was most likely brief—only as long as was needed for the exchange of genetic material. All that energy and effort, from growing ornaments to impressing a prospective mate, just for a few fleeting moments to continue the life of the species.

80 million years ago, the Linhenykus monodactylus scratched its lottery tickets with only one finger:
Meat-eating dinosaurs were very good at finding food, thus their evolutionary success over some 165 million years. But during their time on earth, they kept losing something that might seem important: their fingers. The earliest carnivorous dinosaurs had five fingers, although only four were actually functional. Many later meat-eaters had only three, and evolution left the mighty Tyrannosaurus rex with only two. Now researchers have unearthed the first known dinosaur with only one finger.[...]
The team suggests that the single, clawlike digit was an adaptation for digging, perhaps for insects such as termites.

The Quetzalcoatlus, a dinosaur with a wingspan of 35 feet, is thought to be the largest flying animal in Earth history. Some paleontologists think that it was so big that it wouldn’t have been able to get off the ground. Mike Habib, a scholar of biomechanics at Chatham University decided to investigate this claim. He and his colleague, paleontologist Mark Witton, concluded that this dinosaur could probably fly enormous distances:
So Habib teamed up with Mark Witton, a British paleontologist, to plug in factors like wingspan, weight and aerodynamics into a computer model.
The results, which they presented at a conference last month, were staggering: They revealed an animal that could fly up to 80 miles an hour for 7 to 10 days at altitudes of 15,000 feet. The maximum range, Habib says, was probably between 8,000 and 12,000 miles.

A slab of marble in the Cathedral of St. Ambrose in Vigevano, Italy, appears to contain a cross-section of the skull of a dinosaur:
“The rock contains what appears to be a horizontal section of a dinosaur’s skull. The image looks like a CT scan, and clearly shows the cranium, the nasal cavities, and numerous teeth,” Andrea Tintori, the University of Milan paleontologist who spotted the fossil near the altar, told Discovery News.
Measuring about 30 cm (11.8 inches), the skull was cut in sections as slabs of the marble-like rock were used to build the Cathedral between 1532 and 1660.

The Kosmoceratops dinosaur, which roamed Utah 76 million years ago, may have had more horns on its head than any other dinosaur discovered. The Guardian talked with Scott Sampson, a paleontologist:
The animal, named Kosmoceratops, had an enormous two metre-long skull, was five metres from snout to tail and weighed an estimated 2.5 tonnes.[...]
Kosmoceratops, a relative of the more familiar Triceratops, had one horn over its nose, one over each eye, one protruding from each cheek bone and a row of ten across the frill at the back of its head.
“As far as we know it’s the most ornate-headed dinosaur ever found, with so many well-developed horns on its head,” Sampson told the Guardian.

Since 1980, paleontologists have suggested that a terrible meteorite impact millions of years ago radically altered the Earth’s climate and killed off the dinosaur population. Now a study led by David Jolley of Aberdeen University proposes that there was a second major impact a few thousand years after the first:
In the current study, scientists examined the “pollen and spores” of fossil plants in the layers of mud that infilled the crater. They found that immediately after the impact, ferns quickly colonised the devastated landscape.
Ferns have an amazing ability to bounce back after catastrophe. Layers full of fern spores – dubbed “fern spikes” – are considered to be a good “markers” of past impact events.
However, there was an unexpected discovery in store for the scientists.
They located a second “fern spike” in a layer one metre above the first, suggesting another later impact event.

John Scannella and Jack Horner, researchers at the Museum of the Rockies in Bozeman, Montana, say that the triceratops is the same dinosaur as another one called the torosaurus. The skeletal remains of the three-horned animal are actually the undeveloped, juvenile form of the torosaurus:
Now Scannella and Horner say that triceratops is merely the juvenile form of torosaurus. As the animal aged, its horns changed shape and orientation and its frill became longer, thinner and less jagged. Finally it became fenestrated, producing the classic torosaurus form [...]
This extreme shape-shifting was possible because the bone tissue in the frill and horns stayed immature, spongy and riddled with blood vessels, never fully hardening into solid bone as happens in most animals during early adulthood. The only modern animal known to do anything similar is the cassowary, descended from the dinosaurs, which develops a large spongy crest when its skull is about 80 per cent fully grown.
The torosaurus will now be abolished as a separate species and remains from it reclassified as triceratops.

Paleontologists have discovered what they believe to be the largest known bed of dinosaur bones. It’s in Hilda, Alberta, and covers about 2.3 square km. Their findings suggest that a precursor of the triceratops, found in large numbers at the site, may have traveled in herds numbering in hundreds to thousands of members. Why did so many die at this location? Senior researcher David Eberth thinks that the dinosaurs may have been trapped by rising floodwaters:
Rather than picturing the animals as drowning while crossing a river, a classic scenario that has been used to explain bonebed occurrences at many sites in Alberta, the research team interpreted the vast coastal landscape as being submerged during tropical storms or hurricanes.
With no high ground to escape to, most of the members of the herd drowned in the rising coastal waters. Carcasses were deposited in clumps across kilometres of ancient landscape as floodwaters receded.
“It’s unlikely that these animals could tread water for very long, so the scale of the carnage must have been breathtaking,” said Mr. Eberth. “The evidence suggests that after the flood, dinosaur scavengers trampled and smashed bones in their attempt to feast on the rotting remains.”
