Ancient protein found in marine fossil
Published on May 4th, 2011 | by Admin0
Collagen protein, a type of connective tissue, was found inside the fossilized upper forelimb bone of the mosasaur Prognathodon, a long-dead relative of the monitor lizard.
While this is not the first time proteins have been recovered from dinosaur-era remains, this is the first find of preserved tissues from a marine environment. And the first time they have been found in place in a fossil.
Earlier finds came from extracts of whole dinosaur bones preserved in sediments from what were once river floodplains.
