Paleontologist Mary Schweitzer of North Carolina State University and colleagues apparently have never watched Jurassic Park. Why else would she extract dino "blood" from ancient bones?
A dinosaur bone buried for 80 million years has yielded a mix of proteins and microstructures resembling cells. The finding is important because it should resolve doubts about a previous report that also claimed to have extracted dino tissue from fossils.
... Schweitzer took a look at the pristine leg bone of a plant-eating hadrosaur that had been encased in sandstone for 80 million years. She and colleagues exhaustively tested the sample, sequencing the proteins they found with a new and better mass spectrometer and sending samples to two other labs for verification.
Now they report recovering not just collagen – which conveys little evolutionary information because it is the same in almost all animals – but also haemoglobin, elastin and laminin, as well as cell-like structures resembling blood and bone cells. The proteins should reveal more about dinosaur evolution because they vary much more between species.

Exiting- They truly could make a quantum-leap in gaining knowledge of that period in planetary history.
[from page 2 of the article] "The fish and its unborn offspring probably fell victim to rapid depletion of oxygen in the water, settling to the bottom of the sea where they were gently covered in layers of silt-like mud that hardened over time, according to the scientists."
hah.
And how would oxygen be depleted THAT quickly... almost a split second? It would be gradual... surely the fish wouldn't still be attached to its mother...
Since they only guess at the age, we can only laugh at their guess.
