Gordodon fossil dating back 300 million years & # 39; s known evolutionary timeline & # 39; rewrites – World News

The New Mexico Natural History Museum's rewriting of the ler known evolutionary timeline ini indicated that the m perfectly preserved ini remains of 300 million-year-old reptiles were found in the United States.

Key points:

  • The skeleton belongs to a new kind of scientist named Gordodon kraineri.
  • Gordodon spanish word is derived from gordo or grease and Greek word odon or tooth
  • It was about 1.5 meters long and weighed about 34 kilograms.

This week, the museum announced that the unique structure of the teeth of the teeth of the skull, jaws and reptiles is a herbivore, and it is not known in reptiles older than 200 million years ago.

The bones were a "museum" in a statement, but part of a preserved but incomplete skeleton.

"Skeleton, a sail-backed eupelycosaur, a group of animals that were very successful during the Permian [Period]"said the museum.

"Eupelycosaurs contain the ancestors of mammals, and this is a new concern more closely than dinosaurs."

Spencer Lucas, the curator of paleontology, and his team determined that they were about 300 million years old from the museum, meaning they lived 50 million years ago from the origin of reptiles or dinosaurs crawling early in the Permian Period.

Lucas and research fellow, Matt Celeskey, described the skeleton as a new genus and species, which they call the Gordodon kraineri.

Gordodon, because the teeth have large sharp teeth at the ends of the jaws, the Spanish word is derived from the gordo, (fat) and the Greek word odon (tooth).

The genre name honored Karl Krainer, an Austrian geologist who was informed about the Permian period in New Mexico.

"Gordodon rewrites books by pulling back our understanding of the evolution of such herbivores for about 100 million years." Said.

Gordodon was about 1.5 meters long and weighed about 34 kilograms.

It is believed to be a selective feeder on high nutrient plants due to the improved structure of the skull, jaw and teeth.

Experts in the museum said that other early herbivorous reptiles were not picky, they were clogged on any plant they were facing.

They said that Gordodon had some of the same specialties found in modern animals such as goats and deer.

The fossil bones were discovered by Ethan Schuth in 2013 during a University of Oklahoma geology class field trip near Alamogordo, south of New Mexico.

The field crew spent one year collecting bones from the area and spent more time collecting the hard sandstone surrounding the fossils for research.

The details were found in Palaeontologia Electronica in November.
