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.

It's a simple quiz game. It gives you a word, and you decide whether it's a cheese or  font. How hard could this be? After all, I buy cheese at the grocery store and I have many fonts on my computer. Surprise! There are way more of both in the world than I realized. Link -Thanks, Ginny Turner!

It's been a while since we've seen a new YouTube video from Zach Anner, since he's been busy as a contestant on a TV show from Oprah Winfrey's new network. I started watching this and had to stop and clean the coffee off my screen when he mentioned Israel. -via reddit

Previously: more Zach Anner videos.

Without even realizing it, I posted articles featuring eggplants, zucchinis, and fruit this week. I must be subconsciously dreaming of spring gardening. Or maybe I need more fiber in my diet.

We got a head start on Valentines Day with The 8 Most Romantic Creatures In The Animal Kingdom, from Jill Harness.

Jill also clued us in on The Surprisingly Scandalous History of Early Seattle.

From Uncle John's Bathroom reader came the rather odd Adventures of Eggplant.

The Annals of Improbable Research gave us Cloning of the Zucchini Opiate Receptor.

The Fruit of the Matter was a roundup of odd fruit items from mental_floss magazine.

In the Museum of Possibilities, Steven Johnson presented us with the Name That Weird Invention! contest. A t-shirt goes to Skribbler, who won first place with the entry “Soil-ent Whites”. The second place name was “Grampers” from joe satari, who did not select a shirt.

In the What Is It? game this week, I thought Jared was the first with the correct answer (the item is a bottle opener!) then it turns out that sandyra was actually earlier with the correct answer and I overlooked it. So, both are now winners! Wilbur's answer was the funniest: "These are used exclusively for constructing wooden spiral staircases. (too bad you don't have the hammer in the pic)..." All win t-shirts from the NeatoShop!

The Big Picture blog has a historic collection of forty images from the past two days in Cairo. Demonstrators heard rumors that president Mubarak would step down Thursday. The Egyptian president then delivered a speech in which he announced he was staying in office. Finally, on Friday he resigned from the presidency. This picture was taken only hours ago, after Mubarak handed power over to the military. Link

Illustrator Sam Spratt puts rich detail into subjects you already know and love. In this picture, we see the world of Angry Birds from the poor pig's perspective. The painting is available as a wallpaper. http://samspratt.com/SamSpratt_AngryBirds_Pig_Painting.JPG -Thanks, Rosa Golijan!

Remember the story of the eccentric Frenchman Louis Mantin, who ordered that his opulent mansion and estate be turned into a museum 100 years after his death? National Geographic has a gallery of photographs from inside the mansion, showing the decor and some of Mantin's possessions, like these battling frogs. Link -via Boing Boing

This pelican in Namibia caught a snack in mid-air! Of course, you are wondering how a fish can jump that high. It had a boost from the guy who threw it. The result is the National Geographic Photo of the Day. http://photography.nationalgeographic.com/photography/photo-of-the-day/pelican-walvis-bay-namibia/ -Thanks, Marilyn Terrell!

The Hammersmith and Fulham Council in England is in the process of selling off a building to make room for the West London free school. Twenty community aid organizations are being evicted. One of them is the Afghan Council UK, which advises refugees from Afghanistan.

The report suggested that refugees who use the centre could instead contact the Southern Afghan Club, reports The Mirror.

The Afghan Council UK offers support to Afghan refugees - while the Southern Afghan Club is a dog appreciation society which organises shows in the south of England.

Labour's Hammersmith MP Andy Slaughter said: "Not only are the Tories selling for a song centres that are a hub for their communities but they're doing so in an ­ignorant and cynical way."

This beetle is named Onymacris unguicularis, or the ‘tok-tokkie’ beetle. Why does he look as if he's trying to stand on his head?

He’s developed a rather nifty way of getting a drink. As a sea fog rolls in of a morning the beetle presents himself to it. This is where things get clever, his carapace is made up of a series of peaks and troughs. The peaks are very attractive to water and the fog settles on them, the troughs however are waxy and hydrophobic and the water rolls off the trough and begins to form droplets. The water naturally runs down the inverted beetles body and into his mouth, smashing!

The beetle derived its English name from his drinking habits. Read more at Ever So Strange. Link -Thanks, Danny!

While many folks are dealing with unemployment, those who still have jobs are putting up with more and more cutbacks. Little by little, our personal space at work is shrinking.

According to the International Facility Management Association, the average American office worker had 90 square feet of work space in 1994, but by 2010, that same worker was down to just 75 square feet of personal space in which to stretch out on the job.

Nor are office drones the only casualty of this spacial downsizing trend. Senior company officials have seen their offices shrink as well, from an average of 115 square feet in 1994 to 96 square feet in 2010. Oh, the humanity!

However, big offices are not the status symbol they used to be. Now it is a sign of status when a worker can do at least part of his job completely outside the office. Link -via J-Walk Blog
