A new dinosaur named “Fear Causer” found in Argentina

Paleontologists have discovered a new dinosaur species in Argentina and call it “Llukalkanaliocranianus”. Llukalkan means “fear-causing person” in Mapuche and “aliocranianus” means “abnormal skull” in Latin.

Dinosaur debris was found in the Bajo de la Carpa Formation, a rock mass that straddles the Negro River and Neuquen Province in Argentina. Journal of Vertebrate Paleontology Details of the excavation were released on Wednesday.

Existing about 80 million years ago, this creature belongs to the Abelisauridae, a group of carnivorous apex predators with small arms and large hind legs, most prominent in the Cretaceous and similar to the famous Tyrannosaurus rex. It was.

However, the skulls of these dinosaurs were rare and had coats of arms, horns, and other bumps. The head ridge of Llukalkan aliocranianus may have resembled that of an iguana or Gila monster.

Analysis of the fossilized skull of a dinosaur also revealed that it may have had greater hearing than most abelisaurus.

“A feature of this dinosaur is that it has a cavity in the ear area that other Abelisaurus did not have, which could have given this species a different hearing, perhaps a wider hearing range,” Sun said. Federico Janecini, a paleontologist at a national university, said. Lewis of Argentina and one of the lead authors of the study said: CNN.. “This, along with its keen sense of smell, would have given it a wonderful ability as a predator of this kind.”

The wreckage of the creature was only 700 meters away from the wreckage of another Abelisaurus known as Viavenator exxoni, which was discovered in 2016. Abelisaurus fossil studies show that the dinosaurs were still prosperous shortly before their extinction.

“These dinosaurs were still experimenting with new evolutionary pathways and were rapidly diversifying shortly before they died completely,” said research co-author Dr. Ariel Mendes of the Patagonia Institute for Geological Paleontology. It states in. Press release..
