Finding an old vegetarian reptile brings new evidence of evolution


"We must re-write the history books as the evolutionary cycle of vegetarians continues," Spencer Lucas, curator of paleontology at the New Natural History Museum and faculty, told Efe describing Gordodon's discovery. , the name given to the reptile, "one of the most notable discoveries".

Gordanon, which is 1.5 meters long and weighs about 34 pounds, was discovered in 2013 in Ethan Schuth City, Alamogordo, New Mexico, near the geomologic class of the University of Oklahoma.

The group, led by Professor Lynn Soreghan, contacted the Lucas and Albuquerque Museum, which is responsible for searching for fossils, processing and research in the following years, according to this week's Natural History and Museum of Science. New Mexico (NMMNHS, abbreviated as English).

The unique texture of the teat, the jaws and the type of dental tooth show that it was herbivores, properties not known in such animals over 200 million years of age.

According to Lucas, Gordodon lived in Perm, about 50 million years before they proposed dinosaurs.

"It's more like us than mammals like dinosaurs," said a researcher who says that Gordodon comes from a combination of words in Spanish with "fat" and the Greek word "Odon" or teeth with long, sharp teeth at the tip of the jaw.

Lucas, together with researcher Matt Celes, identified fossil as a new herbal species and size and weight correspond to the corresponding labrador container.

Another remarkable finding is that the first herbivores were considered to be all kinds of cancer, but the reptile found in New Mexico "also eats seeds and fruits" such as sheep, deer and rabbits at the moment, says the researcher. .

"We have indications that Gordodon was more selective in what he ate," Lucas said.
