A sensational discovery by scientists has opened a new chapter in paleontological science, where chromosomes have been unveiled in the fossilized bones of a dinosaur that is 75 million years old. An extraordinary journey through time has brought us into the nucleus of prehistoric cells, revealing the hidden genetic mysteries within the cartilage of a baby dinosaur.
Discovered in northwest Montana, this fossil belongs to the Hypacrosaurus genus and stands as a silent witness to the Late Cretaceous period. Scientists from the Institute of Vertebrate Paleontology and Paleoanthropology (CAS), along with Mary Schweitzer from North Carolina State University in the United States, have detailed the groundbreaking nature of this discovery in the National Science Review.
Microscopic analysis results showcased well-preserved cells within calcified cartilage, and the revelation of cell nuclei and chromosomes brings us closer to understanding how dinosaurs from the past evolved and reproduced. This finding not only reawakens the narrative of dinosaur evolution but also opens the potential to further comprehend the remnants of biomolecules that can endure for tens of millions of years.
By combining new technology and sophisticated analytical skills, researchers successfully demonstrated the presence of original cartilage proteins and even some original DNA in this dinosaur fossil. This discovery introduces a new paradigm, triggering further exploration into the potential unveiling of molecular secrets from a long-locked past.
This finding not only creates a paradigm shift in our understanding of dinosaurs but also stimulates scientific imagination by opening the door to delve deeper into ancient times and genetics.
