Even among dinosaurs, this was especially terrifying.

Scientists have dubbed a new type of carnivorous dinosaur in Argentina “the person that causes fear” by scientists who have found a well-preserved skull of an ancient beast.

Fearless killer Llukalkan aliocranianus They were “among the best predators” throughout Patagonia, now in Argentina, during the late Cretaceous period due to their enormous size, extremely powerful bite, extremely sharp teeth, massive claws, and intense sense of smell.

according to New study Posted on Tuesday about the discovery, the dinosaur’s full name comes from the original Mapuche language for “the one who causes fear” – Llukalkan – and the Latin for “a different skull” – aliocranianus.

The study’s lead author Federico Giancini, a paleontologist at San Luis National University, Argentina, said in A. statement.

The Abelisaurids were a family of dinosaurs averaging about 15 to 30 feet in length that roamed mainly Patagonia and other regions of the ancient Gondwana subcontinent, which today is known as Africa, India, Antarctica, Australia and South America.

Around 80 million years ago, just as the famous dinosaurs dominated the northern hemisphere, this hominid was one of the ten currently known species of appellations thriving on the southern continents.

To date, approximately 10 species of this feared predator have been discovered across Patagonia. While the Pliosaurs resembled the T-Rex in general with short, small arms, they had unusually short and deep skulls that often had crests, protrusions, and horns.

“The peculiarity of this dinosaur is that it contains cavities in the ear area that other abilisorids did not possess, which could give this species different hearing capabilities, and possibly a greater auditory range,” said Gianchini. Reuters.

The study showed that the dinosaur the size of an elephant had a strange and short skull with jagged bones, so in life its head was swollen and protruding similar to the current reptiles like a gila monster or some iguana.

Although he may have lived, fossil evidence of Llukalkan adaptations suggests that the Abelisaurids were thriving just before the extinction of the dinosaurs.

“These dinosaurs were still experimenting with new evolutionary paths and rapidly diversifying before they became completely extinct,” said Ariel Mendes, co-author of the study, of the Patagonia Institute of Geology and Paleontology in Argentina.

The study was published in the peer-reviewed Journal of Vertebrate Paleontology.
