New carnivorous dinosaur fossil discovered in Argentina Scientists in Argentina

New carnivorous dinosaur fossil discovered in Argentina Scientists in Argentina have unearthed the well-preserved skull of a carnivorous dinosaur that roamed northern Patagonia some 85 million years ago. A small snout, an animal that listens deeply and stings that made it difficult prey.

New carnivorous dinosaurThe researchers said that the dinosaur named Luluccan allocranianus is about 16 feet (5 m) long, a member of the carnivorous group called Abelisaurids. Which in South America and other parts of the southern hemisphere of the Earth during the Cretaceous period was prosperous, the investigators said Tuesday.

Llukalkan, which means “local coward” in the local Mapuche native language, may have directly competed against a cousin who was equally influential and slightly larger. Just 700 meters from where Lukalukan’s fossil skull was found, scientists had previously unearthed the remains of another carnivorous dinosaur, called Viavanetter axonii.

Both were abelisaurids, a group of bipedal predators with short skulls, sharp, pointed teeth, extremely short arms with short fingers, and sometimes unusual short crests and horns. Abelisaurids were generally medium in size compared to giant carnivorous dinosaurs such as Tyrannosaurus rex (New carnivorous dinosaur).

Scientific and Technical

Which lived in North America about 15 million years after Luluclan, and Galiongosaurus. Which lived in Patagonia about 15 million years before Lulucalan. The lead author of the National Council for Scientific and Technical Research of Argentina (Sonic) and the National University of San Luis said:

Yes, it is very unusual to find two abelisaurids living in the same area and almost at the same time. Study published in the Journal of Vertebrate Paleontology. “Llukalkan was a little smaller than the Viavenator, however, if they lived together, they would surely share the same ecological niche and feed on the same prey.

Dinosaur discovered in Argentina

So they competed with each other. They were and, why not, would eat each other “Gianni added.” Today, hunters of different species but from the same family live together in the same ecosystem, such as lions, leopards and cheetahs. Llukalkan’s skull was approximately 50 cm long. A large percentage of cranial bones were found, including a well-preserved skull.

A peculiarity of this dinosaur is that it has cavities in the ear region that were not close to other abelissauroids. Which could give this species a different hearing ability, possibly a larger hearing range, Gianchini said. Good conservation allowed us to study the inside of the brain box using tomography and thus estimate the size of the brain (New carnivorous dinosaur).

Based on the musculature of Llukalkan’s jaw, there was a powerful bite, and his teeth could rip the flesh off his prey. Unlike some abelisaurids, its skull was not rough. No bone was found from the rest of his body, although researchers have a good idea of his body plan based on other abelisaurids. He estimates that Lulukalan weighed between one and five tons.

Age of dinosaurs

Patagonia has produced important dinosaurs in recent decades. Llukalkan’s discovery allows a deeper understanding of the ecosystems of northern Patagonia during the Cretaceous. The last chapter of the age of dinosaurs. Llukalkan inhabited a semi-arid environment with a seasonal climate, feeding on dinosaurs that ate a wide variety of plants.

Paleontologists in Argentina have identified a new species of usauropod dinosaurs. Newly discovered long-necked dinosaurs survived early Jurassic global warming. True sauropods that lived 179 million years ago. After the mysterious disappearance of the nonuseuropod sauropod.

Reconstruction of the life of Bagulia alba. The most recently identified dinosaurs lived in Argentina during the Early Jurassic era. The ancient creature was a type of eusropod. A group of strict long-necked herbivorous quadruped dinosaurs that had evolved from the Early Jurassic to Upper Cretaceous.

Biomechanics & locomotion

This animal, called Bagualia alba, is actually the oldest eusropod dinosaur ever known. Soropodomorpha is the first major group of dinosaurs that has diversified into many recorded vegetarian lineages around the world, Dr. Diego Pol told the Agidio Ferruglio and Sonic Paleontological Museum and their colleagues from Argentina, the United States and Germany.

The first 40 million years of seropodomorph development are characterized by the coexistence of various lineages with large disparities in body size, ranging from small (less than 10 kg) to large (more than 5 tons) biomechanics and locomotion. Feed the types of. Quadruple early seraprodes.

In the Middle Jurassic, Europod dinosaurs were the only surviving sapropodomorphs. The remains of at least three Bagulia alba individuals, including a partial skull and cervical vertebrae, were found at the same site in Bagual Canyon in the Canadon Asphalto Basin, central Patagonia.


Paleontologists reported that “soropods have become the dominant group of large herbivores in terrestrial ecosystems, as many related lineages have become extinct by the end of the Early Jurassic,” the paleontologists explained. The causes and exact timing of this major wildlife change, as well as the origin of the eusuropods, have not been clear, mainly due to the rare dinosaur fossil record from this time.

The terrestrial sedimentary successors of the Canadon Sphalto Basin have documented this important interval of divine evolution. To shed light on the extinction of the sauropodomorphs, Dr. Poole and his co-authors investigated the fossil flora and fauna of the Canadon Asphalto Basin. After a great magical event that affected southern Gondwana 180 to 184 million years ago.

Greenhouse vegetation

They found evidence of a severe alteration of the ancient climate and a drastic reduction in flower diversity, leading to the emergence of conifers with small leaves with hooves. They were the reason. They believe that the non-propopod sauropodomorphs became extinct by the soft flora, replacing the greenhouse vegetation.

After the event, Bugulia alba and other usropods displayed traits that were likely critical to their success after this environmental change, the researchers said. Their elongated necks provided feeding envelopes and maximum browsing heights, and their large body size is related to expanding intestinal capacity and fiber digestibility.

Their deep and strong skulls and jaws indicate large. Broad teeth with high bite force and their long jaw gait and thick enamel (over 700 m 700 m) and extensive aspects of high volume and high vegetable shear wear. Feeding has been interpreted as an adaptation to fix. On hard and fibrous plant material.
