It was not this kind of animal before the course
TUCSON (EFE) – The discovery in New Mexico of the fossil of a 300 million-year-old herbivore reptile, indicated to be the oldest of its kind, forces the rewrite of the evolution of these animals, according to one of the authors of the discovery.
"We will have to rewrite history books by taking back the evolution of grazing animals," says Spencer Lucas, a palaeontologist at the Natural History and Science Museum in New Mexico, who says this finding is "one of the most significant discoveries . "
Gordodon, the reptile name, was 1.5 meters long and weighed 34 kilos. It was discovered in 2013 near the town of Alamogordo by Ethan Schuth on a trip with his class of geology at the University of Oklahoma.
The group, led by Professor Lynn Soreghan, contacted Lucas and the Albuquerque Museum, an entity that was responsible for the extraction, treatment and fossil research in the coming years.
The unique structure of the skull, jaws and tooth type of the reptile indicates that it was a herbivore. These characteristics were not known in those animals older than 200 million years.
According to Lucas, Gordodon lived during the Permian period, 50 million years before the dinosaurs made their appearance.
"It is more like us mammals than dinosaurs," says the researcher, who explains that the name Gordodon comes from the combination of the word "fat" Spanish and Greek "odon" or tooth, which alludes to the long teeth that the species had at jaw tip.
It was thought that the first herbivores had eaten all kinds of plants, but Gordodon ingested both seeds and fruits.
