Earth is round or flat religion1/20/2024 ![]() ![]() They applied the latest technology to identify collagen protein sequences in the thigh bone of the Cretaceous hadrosaur, Brachylophosaurus Canadensis. In Schweitzer’s North Carolina laboratory, Elena Schroeter and colleagues have now repeated Schweitzer’s 2009 study. ![]() Confirmation of Cretaceous CollagenĬollagen is the main structural protein found in skin and connective tissues. The latest additions to this growing body of research came from two far-flung research centers, again asserting that dinosaur soft tissues and proteins have survived not only in fossilized material believed to be 80 million years old, but even in fossils dated 195 million years old. ![]() In the face of continuing skepticism, she and others have continued applying new technology to old bones, seeking to prove that that the proteins they have found are the real deal, not modern contaminants. Mary Schweitzer published papers in 20 asserting that her team had isolated collagen from dinosaur bone. After all, how could fragile biological molecules or soft tissues be preserved for millions of years? Mary Schweitzer found red blood cells and blood vessels inside a fossilized dinosaur bone, much of the scientific community still found the idea preposterous. When Jurassic Park hit the box office in 1993, the idea that dinosaur DNA-as in the movie-or proteins could still be available for study in the modern world seemed to be pure fantasy. Observable science confirms that preserved collagen fragments in dinosaur bone are authentic, but does not demonstrate the protein can be preserved for millions of years or that dinosaurs evolved into birds.Collagen fragments in dinosaur bone have sequences resembling those in alligator and bird collagen. ![]()
