A previously undiscovered dinosaur species was unearthed in an excavation in Argentina, and a predator similar to Tyrannosaurus was named suitable for what we know so far: Llukalkan aliocranianusOr “the person who causes fear”.
Can grow to be as long as an elephant, with sharp teeth and strong bite force, L. aliocranianus It would undoubtedly be a frightening sight for any other creatures that occurred on it during the late Cretaceous, which led to the extinction of the dinosaurs 66 million years ago.
The new species is celandine, although it may have better hearing (similar to modern crocodiles) than the nine other species in the family discovered so far. Researchers say that dinosaurs also have huge claws on their feet and have a keen sense of smell.
“This is a particularly important discovery because it shows that the diversity and abundance of Pseudo-Belarus not only in Patagonia but also in other regions during the twilight period of dinosaurs,” Saint State University Said the paleontologist Federico Gianechini (Federico Gianechini). Luis is in Argentina.
Patagonia and the rest of the ancient supercontinent Gondwana-now split into Africa, India, Antarctica, Australia, and South America-are places where wanderers roam.
Although their short forearms make them look like Tyrannosaurus, Their skulls are unusually short and deep, usually with crests, bumps and horns. This special dinosaur will bulge on its head like the Gila monster lizard.
Researchers have determined L. aliocranianus Share the same part of the world with another god at the same time, Viavenator exxoni, Although the new species will be smaller.
Ariel Mendez, a paleontologist at the Institute of Geology and Paleontology of Patagonia, Argentina, said: “These dinosaurs are still trying new ways of evolution and are rapidly diversifying before they are completely extinct.”
Part of the fossil remains of the “fear-causing person” includes a brain box that shows a unique feature among belisauids: a small posterior inflated sinus in the middle ear area, which helps croc-like hearing.
The hearing probably improved the dinosaur’s ability as a predator, the research team said, L. aliocranianus with Exxon Barau Will be one of the most dangerous carnivores at the time.
From about 80 million years ago, there may be more in the area-for the sauropods and furileusaurs (“hardback lizards”) that make up this part, this period seems to be a prosperous period. . family.
Gianecini said: “This discovery also shows that we may not have discovered more belisauris, so we will look for other new species and have a better understanding of the relationship between Furilesaurs.”
The research has been published in Journal of vertebrate paleontology.
