Traces of DNA found in the fossil of a duck-billed dinosaur
An article published in the journal “National Science Review” reports evidence of the identification of proteins, chromosomes and DNA markers in the fossil cartilage of a Hypacrosaurus stebingeri nestling, a dinosaur belonging to the hadrosaur family dating back to around 75 million years ago, in the Cretaceous period. A team of researchers led by Alida Bailleul of the Institute of Vertebrate Paleontology and Paleoanthropology, China, used chemicals that bind to DNA in living cells on fossil bone fragments resulting in a fluorescence indicating that they bonded to the original molecules and not to external contaminants. Jurassic Park remains science fiction because the fragments found may have undergone various alterations but any trace of cell structures, proteins and chromosomes could offer new information on these dinosaurs.
