Different dinosaurs species would have traveled together

Did these super-predators work together to hunt this game? Moreover, Has the herd formed in order to be able to defend itself against such threats? Therefore, In African meadows, lions often follow herds made up of several species of herbivores and hunt them in groups. For example, Would these fingerprints that paleontologists have been found due to a similar situation?

“It is quite evocative to think that this situation is similar to what we can see today in the plains of Africa. Moreover, ” says Brian Pickles. Therefore, “We do not know when the brands were made, the Tyrannosaures could have very well passed by the first. »»

Some researchers who have not taken part in this discovery question the team’s conclusions.

According to Anthony Romilio. paleontologist of the University of Queensland, Australia, although the dinosaurs surely formed herds in which several different dinosaurs species would have species mix, the interpretations of the imprints that scientists are not good.

“As researchers, we are naturally attracted by the possibility that these fossils offer. But this excitement can sometimes lead to overinterpretations, ”explains the paleontologist. The traces of ceratopsians. ankylosaurus are similar in their form, and it thinks that it is more possible that they are poorly preserved imprints of large Hadrosaurs.

“This interpretation may not have the same effect. but it is more in agreement with what is known about fossil fingerprints and their circulation,” he continues.

Christian Meyer, a paleontologist from the Swiss University of Basel, is also skeptical. He describes the discoveries of “speculative”.

“I find that preserving traces. including their taxonomic summons, has no solid basis; There is no full circulation that would show the walking scheme, ”explains Christian Meyer. “In addition. the interpretation of mixed herds is, in view of the facts, a little different dinosaurs species would have pulled by the hair in my opinion. »»

Since the up -to -day that has motivated this new study. Brian Pickles and his colleagues have declared that they have discovered more than ten new traces of traffic traffic. With so many imprints. Brian Pickles explains that we will soon have more elements to assert or invalidate if the dinosaurs are indeed flocks of several species.

“There is potentially much more to say that what we have been able to reveal until then,” he concludes.
