Although dinosaurs disappeared from the Earth millions of years ago and therefore ceased to be the predominant species on the planet, humans are still determined to learn more about how they lived, the various forms they took, and so on. Few questions, until now, have been directed at a key question that could have a starting point: what was the origin of dinosaurs?
The scientific community is currently engrossed in the dissemination of research that could well be the answer to the big question about the emergence of these magnificent creatures on Earth. The specialized website Earth is echoing this unprecedented breakthrough published in the journal Current Biology and led by Joel Heath of University College London.
Where did the first dinosaurs appear on Earth?
Places like Argentina or Zimbabwe had been, for example, the well-known points of discovery of many dinosaur fossils. Research, however, suggests that the first dinosaurs may have come from areas that are now the Congo Basin, the Sahara Desert or the well-known Amazon rainforest.
The reason for the belief that the first ones are not those found in the countries mentioned is due to the detailed study of the fossils, whose differences indicate that the dinosaurs had already been populating the planet for several million years. In fact, it is considered that the lack of finds in several parts of the Earth with respect to fossils does not imply that in those areas they did not exist, but that it has not yet been thoroughly studied.
This novel research argues that the first dinosaurs may have originated in Gondwana. It also argues that this species was not originally the predominant one, but coexisted with other animals such as crocodiles. The study even claims that the first dinosaurs were not as large as their descendants and that it was evolution that led to this.
