  • Dinosaurs and their Ancestors Lived and Died Side by Side in Prehistoric Time

Dinosaurs and their ancestors co-existed in prehistoric times. There is fossil evidence for this that has been unearthed recently.

There was a time when dinosaurs ruled the earth. They comprised a large group of animals. Reptiles that were amphibians to boot were included among the rank and file of these curious creatures. Some of them grew to monstrous proportions.

All the land masses on the planet had these dinosaurs moving around on them. They also gave rise to the first avians. The dinosaur family comprises one of two branches of the dinosauromorpha. The other one were the lagerpetids.

While the lagerpetids resembled the smaller dinosaurs, they were in fact quite different in their nature. Yet the latest evidence shows that these two families co-existed for many years.

In fact, they continued to live side by side well into the Triassic Age. Lagerpetids began to appear 235 million years ago. However, they never survived for long. This finding occurred in the Santa Maria Formation in the southern region of Brazil.

Fossils of two species, one a sauropod and the other a lagerpetid, were found. These fossils were retrieved from the same rock showing that they lived side by side, according to IBT.

This happens to be the first time that a dinosaur and a lagerpetid species have been found together. The fact that they were together in the same boat (so to say) shows that the past prehistoric picture we have formed in our minds may have to be changed.

The co-existence however only existed for a short while. The two species shared time and space approximately 30 million years ago.

The dinosaurs were basically thought to have offered a great deal of competition to the lagerpetids and driven them into extinction. Yet now we know better. They in fact lived side by side with them.

This research paper got published in the journal Current Biology.
