Thyreophoran Jakapil kaniukura dinosaur was found in Argentina – USA today

Researchers in Argentina have discovered the remains of a small herbivorous dinosaur with protective mutations, indicating that the group it belonged to lived in a much wider area than originally thought.

The dinosaur was part of the Cretaceous period, the last age of the dinosaurs, and lived between 97 million and 94 million years ago.

said Facundo Riguete, a paleontologist at the Felix de Azara Natural History Foundation – Maimonides University and the National Council for Scientific and Technical Research.

The results were published this month in the scientific journal Scientific Reports.

“Jakapil is the first basal thyrofuran of its kind found in South America,” said Rigueti, one of the authors of the paper. “Until recent years, discoveries of thyrofuran were rare in the Southern Hemisphere.”

He said the former therofuran, also known as the basal therofuran, lived mostly in North America, Europe, Asia and possibly Africa.

What was the shape of the dinosaur?

The found remains belonged to a sub-adult Yacapel – not a young individual, but not an adult male either. Rigetti said the team examined his bones under a microscope and said the tissue showed a reduced rate of growth, which doesn’t happen with juveniles.

He said the dinosaur weighed nearly as much as a domestic cat, or roughly 8 to 15 pounds, and its teeth were leaf-shaped, like those of Scelidosaurus or Ankylosaurs.

It’s possible that Jacapelle walked upright, had a beak and was able to deliver a very powerful bite, though not as strong as some other dinosaurs such as ornithopods or ceratopsians, Rigotti said.

Also important about Jacapelle?

This is the first time that a basal thyrophoran has a predatory bone, or beak, at the front of the lower jaw. It also has “limited arms” in terms of length and durability, he said.

He said new research efforts in South America and Africa could lead to similar discoveries.
