Original Collagen Discovered in 66-Million-Year-Old Dinosaur Bones Challenges Fossilization Assumptions
A team of researchers has uncovered compelling evidence that original collagen—the primary protein in bone and connective tissue—can persist inside dinosaur fossils for tens of millions of years. This finding upends a long-standing assumption in paleontology that such organic molecules would degrade completely over geological timescales.
The discovery, involving 66-million-year-old specimens, suggests that under specific conditions, delicate biological molecules may survive far longer than previously believed. If confirmed through further study, this could revolutionize how scientists approach dinosaur research by providing direct molecular clues about dinosaur biology, evolutionary relationships, and the mechanisms that allow ancient proteins to withstand the test of time.
The implications extend beyond identifying proteins. Understanding how these molecules survive could inform preservation techniques in fields ranging from archaeology to materials science, while offering paleontologists a new toolkit for exploring questions about dinosaur physiology and evolutionary history that fossilized bones alone could not answer.
