Dinosaur Fossil Could Contain Cells

A 70-million-year-old Tyrannosaurus Rex fossil dug out of a hunk of sandstone has yielded soft tissue, including blood vessels and perhaps even whole cells, US researchers reported. Paleontologists forced to break the creature's massive thighbone to get it on a helicopter found not a solid piece of fossilized bone, but instead something looking a bit less like a rock. When they got it into a lab and chemically removed the hard minerals, they found what looked like blood vessels, bone cells and perhaps even blood cells. ViaTECHNOLOGY | NEWS | tvnz.co.nz
