The discovery in New Mexico (USA) of herb reptile fossil of about 300 million years old, and has been designated as the oldest fossil of herb reptiles, forces to "rewrite" the evolution of this class of animals, according to Efe. researchers discovered.
"We will have to rewrite history books, taking the period of evolution of the herbal animals further back," said Spencer Lucas, curator of Paleontology at the National Museum of Natural History and Science, to Efe, who described the discovery of Gordodon. , a name given to the reptiles, as "one of the most significant finds".
Gordodon, which is 1.5 meters (5ft) long and is about 34 kilograms (75 pounds), in 2013 near the town of Alamogordo, New Mexico, by Ethan Schuth during a trip with a # 39; to geology class Oklahoma University.
The group, led by Professor Lynn Soreghan, joins Lucas and the museum located in Albuquerque, an entity responsible in the following years for fossil extraction, treatment and research, according to National Museum of Natural History and Science this week. New Mexico (NMMNHS, for its acronym in English).
The unique structure of the skull, the bend and the type of reptile teeth show that it is herbal herbs, which were not known in this type of animal over 200 million years of age.
According to Lucas, Gordodon lived in the Electricity Period, about 50 million years before they suggested dinosaurs.
"We're more like us, mammals, than dinosaurs," explained the researcher, who states that the name Gordodon comes from the combination of the word "fat" Spanish and the Greek word "odon" or tooth, because of its long and punctual teeth at the front of the lines.
Lucas, together with researcher Matt Celeskey, pointed out the fossil as a new species of herbs and, in terms of size and weight, matches what is now a labrador dog.
Another significant aspect of the discovery is that the first vegetarians are considered to eat all plant types, but reptiles found in New Mexico also adopt seeds and fruit, "said researcher as sheep , deer and rabbits.
"We have signs that Gordodon is more selective in what it's eating," said Lucas.
