Dinosauromorphs origin becomes much more clear in the new study

The beginning of dinosaurs is among the biggest mysteries of the world. Notwithstanding the fact that scientists have discovered large amounts of fossils that relate to the existence of huge dinosaurs, there isn’t much evidence on the origin of the beasts.

Scientists have named the earliest specie of dinosaurs as dinosauromorphs. Nonetheless, despite all their efforts they haven’t been able to pinpoint a probable date of their origin. There have been substantial differences when it comes to different estimates of their origin.

There are researches suggesting that dinosauromorphs actually appeared anywhere from just at the end-Permian extinction about 252 million years ago or closer to the arrival of the first dinosaurs around 231 million years ago. But these are simply hypothesis and not a final word on the origin of the first species of the dinosaur.dinosaur Torvosaurus european

There are signs that the mystery may be nearer to be solved. A latest study from the Proceedings of the National Academy of Sciences has come out with a detailed report on the origin of the dinosauromorphs.

The study conducted by the Proceedings of the National Academy of Sciences claims that dinosauromorphs actually emerged around 234 million to 236 million years ago or much closer to time when dinosaurs originated.

Randall Irmis, co-author of the study says, “What was unexpected was that these earliest dinosauromorphs were so in late time. We thought that they were part of this radiation soon after end-Permian mass extinction”.

A curator of paleontology at the Natural History Museum of Utah, Irmis goes on to add, For so long, people have been asking why did dinosaurs become so successful and what was special about them…This shows that dinosaurs were just a part of a bigger radiation of dinosauromorphs and we should be really asking the question why dinosaurmorphs became so successful.”

The scientists working on the study employed latest scientific methods to get to the truth. Team that had scientists from many nations including Brazil, Argentina and California employed radioactive isotope measurements to date zircon crystals. It is famous for its fossils of early dinosaur relatives and thus an ideal place to study the relationship between early dinosaurs and dinosaurs. The new findings have opened new dimensions to the research.
