Scoperta accidentale di sangue e collagene in fossili di dinosauro

  An amazing discovery could rewrite textbooks, after a paleontologist accidentally found blood and soft tissue preserved in tattered dinosaur fossils. If proven, science expects answers to age-old questions, including: "Can we resurrect dinosaurs?"

The red blood cells and collagen fibers were discovered by chance when Imperial College London’s Sergio Bertazzo and Susannah Maidment were examining the buildup of calcium in human blood vessels. Bertazzo wanted to perform a few tests using electronic microscopes and ended up asking the Natural History Museum for some fossils to test his findings, according to the IB Times.

They received eight pieces, all estimated at 75 million years old.

What the pair found could prove we’ve consistently been looking at dinosaurs in the wrong way: it suggests that nearly every fossil science studied in the past century could contain similarly well-preserved blood and tissue samples, answering questions on dinosaur evolution, physiology, behavior, and whether their DNA could also be intact. From there on in, we’re entering sci-fi territory.

The accompanying study was publishedpublished in the journal Nature Communications.
