British scientists have found any traces of cells and collagen in dinosaur fossils with an age of 75 million years, according to a study published today in the journal Nature Communications.
The researchers found structures that could be red blood cells and collagen fibers similar to dinosaur bones belonging to the Cretaceous period, which ranges from the late Jurassic period (about 145 ago million years ago) until the beginning of the Paleocene (65 million years ago) -.
This finding shows that the remains of organic structures in fossils may be more common I thought.
Previously, they had been located components of soft tissue such as cells and protein-like molecules, in other fossils tens of millions of years old, but Only in exceptionally well preserved specimens.
The identification of these tissues also raised controversy in the scientific community.
For a long time it was believed that the protein molecules decomposed in a short period of time, and are not kept for more than 4 million years.
Sergio Bertazzo and Susannah Maidment, researchers from Imperial College London who led the work, have reported finding traces of organic structures in eight dinosaurs of the Cretaceous, the last period of the Mesozoic Era.
Some of those bones belonging to one of the dinosaurs, contain similar to the collagen structures, a protein that has a braided feature and consists of essential amino acids.
The study could be key to paleontologists, it opens the door to understanding the biology of prehistoric animal and the relationship between different species.
Bertazzo has called for caution to the findings, and He said that need further research to confirm “what we are seeing in the fragments of dinosaur”
