Dinosaurs are an ancient group of animals that has fascinated the world for centuries. They played an important role in cinematography and literature, and if it weren’t for archeological discoveries, people would have thought them to be just the result of a spectacular imagination. There are many theories related to their entire extinction, including the devastating impact of a massive asteroid. However, dino teeth may be the answer to whatever triggered their annihilation.
A recent study appeared in the Proceedings of the National Academy of Sciences and brought a new theory to the world related to the extinction of dinosaurs. The findings were possible thanks to a team of scientists at the University of Calgary, the American Museum of Natural History, and Florida State University.
The study sheds light on the fact that dinosaurs used to incubate much to the similarity of reptiles than birds as previously thought. Based on the data collected from dino teeth, the scientists discovered that dinosaurs needed from three to six months to hatch their eggs. This is a far too long a time span than scientists believed.
The side effects of such a lengthy period of incubation might have triggered fatal repercussions. The new study links this discovered element to the cause of dinosaur extinction. It seems that the dinosaurs were not able to keep up with the new generation of fauna. New populations of mammals, reptiles, and birds hatched more rapidly which led to the well-known annihilation event 65 million years ago.
The latest technology allowed scientists to discover secrets that were until recently well kept. Thanks to CT scanners, the researchers were able to decipher the mysteries that were preserved in dino teeth. There is still little known about the embryology of dinosaurs, but once people continue their discoveries, this field will answer many questions related to their life history and evolution.
Unfortunately, there were only a few dinosaur embryos with dino teeth discovered so far. While the adult part of a dinosaur remained no secret to scientists, the dinosaur embryology is unexplored yet. So far, it was easy to understand a new theory related to dinosaur extinction. The prolonged incubation presented more occasions for nature to play havoc with dinosaurs. Parents were more prone to starvation and fell more easily victim to predators or environmental phenomena like floods.
