The skull of a carnivorous dinosaur that lived 85 million years ago has been excavated in excellent condition by Argentine researchers in Patagonia, writes the Zala County news portal

The dinosaur named Llukalkan aliocranianus may have been about 5 meters long and belonged to the family of carnivorous abeliszaurids.

These two-legged dinosaurs with medium stature, short skulls, sharp and serrated teeth, extremely short front limbs, thin fingers, and often with unusual margins and tiny horns on their heads lived in what is now Crete and other regions of the southern hemisphere. period.

Barely 700 meters from Llukalkan’s petrified skull, researchers have previously excavated the remains of another abeliszaurid, Viavenator exxoni.

“It is extremely unusual to find two abelisuraurids that lived in the same area and at about the same time.”

– said Federico Gianechini, a paleontologist at the Argentine State Center for Science and Technology (CONICET) and the National University of San Luis, who is the lead author of a study published in the Journal of Vertebrate Paleontology.

“The Llukalkan was slightly smaller than the Viavenator, but if they lived together, they must have shared the same organic slice, hunted for the same, meaning they competed with each other and could even devour each other.”

The expert explained. He added:

“Today predators of different species but in the same family, such as lions, leopards and cheetahs, live together in a given ecosystem.”

Llukalkan’s skull was about 50 centimeters long. Specialists have found a significant percentage of skull bones, including the skull.

“One of the special features of this dinosaur is that, unlike other abelisuraurids, it had cavities in the ear area, which could mean a unique hearing ability, perhaps a larger hearing range.”

Gianechini said.

Based on the muscular system of the jaw, the researchers came to the conclusion that

the Llukalkan, whose name in the local Mapucse language does so that “he who aroused fear” had a powerful bite, easily tore the flesh off his prey with his teeth.

Although the rest of Llukalkan’s skeleton has not been unearthed, based on the structure of the other abeliszaurids, the researchers estimate that its weight may have ranged from 1 to 5 tons.

The bones of armored dinosaurs were examined by ELTE researchers

In their latest research, the staff of the Department of Paleontology of the Eötvös Loránd University and the University of Guelph, Canada investigated the formation and possible role of the ridges and bumps on the skulls of armored dinosaurs on the finds found at the Iharkút in Bakony.

The rich armored dinosaur (Hungarosaurus) finds from the Bakony dinosaur site provided a unique opportunity for researchers to better understand the development, diversity, and potential role of this skeletal feature in this group of nearly 130 million years.
