‘The one that causes fear’: The newly discovered dinosaur was a real meat-eating terror

The Lulucalcan Eliocranius eating meat was a giant dinosaur that would be at the top of the food chain.

There is a tradition of naming dinosaurs infamously. “Tyrannosaurus rex” means “king of tyrannical lizards.” In 2020, scientists will name a new species “Cutting death. Say hello to the “Tooth Dinosaur” now found in South America.

Llucaccan aliocranians roamed present-day Argentina about 80 million years ago. It reached more than 16 feet (5 m) in length and had a short head divided by beaded bones that looked like a jumbo-sized wet monster.

A team of researchers led by paleontologist Federico Giannachini of the National University of San Luis in Argentina published a paper on dinosaurs this week in the Journal of Vertebrate Paleonology.

“This is a particularly important discovery because it suggests that the diversity and abundance of Abelis ur Reeds was noticeable not only in Patagonia, but also in more endemic areas during the dinosaur eve,” Jinacheni said in a statement from journal publishers Taylor and Francis Group .

Llucaccan aliocranianus is a species of Cretaceous period abelissaurids, bipedal, short-armed dinosaurs that live in t. It was similar to Rex. The name is a combination of Map Chushe – the indigenous language of South America – and Latin. Lluclacan means “one that causes fear” and aliocranians are Latin for “various skulls”.

With the fossil lead of a well-preserved brain, scientists helped to describe the hearing abilities of the Lulcan aliocranians.

Scientists have discovered parts of the skull, including a well-preserved case of the brain.

Fossil shows that the Lukalcan aliocranians had some different features than its cousins, most notably “a small posterior sinus filled with air in the middle ear area.” “These findings suggest a different hearing adaptation from Abelis ur Reeds, and possibly a keen sense of hearing,” said Ariel Mendez, co-author of the study at the Patagonian Institute of Geophysics and Paleontology.

T. Fierce, stubborn-armed dinosaurs like Rex have long captured people’s imagination. The Lulukalkan Aliocranians may not be a name recognition, but it does create an interesting history of the meat-munching dinosaurs that once ruled South America.
