Archaeological News: Scientists Discover Remains of NEW CAT-Sized Dinosaur | Science | New

Argentinian paleontologists have discovered a dinosaur that weighed about the same as the average cat that roams the streets today. The remains of dinosaur, which was called Jakapil kaniukura, weighed between 4.5 and 7 kilos according to the estimates of archaeologists. However, the team of scientists discovered that the remains were neither a fully grown adult dinosaur nor a juvenile either. Although the dinosaur was small, measuring less than five feet long, scientists discovered other features that allowed it to protect itself.

It had serrated, leaf-like teeth with protective spikes along its neck and back.

Due to its “reduced arms” – similar to those of a T-Rex – paleontologists believe it walked on its hind legs.

Like a stegosaurus, the Jakapil belonged to the group of thyreophoric dinosaurs – known as “armored dinosaurs”.

However, Jakapil differs from other basal thyreophores.

Paleontologists found it to be the first to have a predental bone or keratin beak at the front of the lower jaw.

His name, “Jakapil” translates to “shield bearer” in Puelchean or Northern Tehuelchean.

Paleontologists said they chose to name it in the languages ​​spoken in Argentina.

The journal, whose lead author was Facundo Riguetti, reads: “The specific epithet, comprising kaniu (ridge) and kura (stone), refers to the diagnostic ventral ridge of the mandible. [the lower jaw]and comes from the Mapudungun language.

“These languages, currently spoken by more than 200,000 people, have been combined as a tribute to the two coexisting indigenous populations of Northern Patagonia, South America.”

This group of dinosaurs lived from the Lower Jurassic until the Cretaceous, the last era of dinosaurs.

Part of the results, published online this week in the scientific journal Scientific Reports, read: “Jakapil also shows that early thyreophores had a much wider geographic distribution than previously thought.

“It is a member of an ancient basal lineage of thyreophores that survived into the Late Cretaceous in South America.”

Chief paleontologist Sebastián Apesteguía and his colleagues have spent the past decade digging up the remains.

Mr. Apesteguía and his team revealed that they had found part of a skeleton as well as 15 tooth fragments from the Jakapil.

The remains are thought to be between 97 and 94 million years old.
