Recently Scientists have discovered organic material conserved in 75-million-year-old dinosaur fossils, including cartilage cells, chromosomes, and DNA.
Chinese Academy of Sciences in Beijing researchers and North Carolina University in the US Investigator published a paper on National Science Review recount the discovery.
The organic material was found within the skull fragment of a Hypacrosaurus. The researchers confirm that it was a duckbill dinosaur.
Inside the fossils, researchers found cells, chromosomes and Dinosaur DNA. Some of which appeared to have frozen in the process of cell partition. The reports is from National Geographic study.
Researcher also observed what appeared to be darkened balls same as nuclei, the cellular structures that store DNA.
Alida Bailleul says the exciting new results add to growing example that cells and some of their biomolecules can persist in deep-time. Alida Bailleul is the lead authors of the paper.
Scientists Thought about Dinosaur
The Scientist also added that ”DNA can preserve for more than tens of millions of years. We hope that this research will encourage scientists working on ancient Dinosaur DNA to push current limits. It can also use the modern methodology in order to reveal all the unknown molecular secrets that ancient DNA have.”
These unknowns, as well as protocols that are still in development, fuel the ongoing debate over what the biological tidbits inside dinosaur bones represent. The research on the cartilage looked at its microscopic details and used chemical stains that is bind to DNA. In contrast, the study on the Centrosaurus bone used DNA sequencing to understand the nature of the genetic traces inside it. But it did not look at its microstructure. One of the largest difficulties in the ongoing debate, Barnett says, is a lack of replication project. Nevertheless, molecular paleobiology is developing now the standards of evidence and protocols as it continues to search for clues held inside ancient bones.
We do not found any reports on whether the DNA can be used to recreate dinosaurs for a theme park.
