A new species of dinosaur that was 16 feet long and roamed Brazil 70 million years ago has been discovered by paleontologists.

The formidable predator named Kurupi itata by the researchers had short arms, a stiff tail and was well adapted to walking, fossil analysis revealed.

Its remains were found in Monte Alto, a municipality in the state of So Paulo, one of Brazil’s richest sites for dinosaur discoveries.

abelisaurids

The Abelisauridae were a striking family of theropod dinosaurs 16 to 30 feet long that were found primarily in Patagonia and other areas of the ancient southern supercontinent Gondwana.

Gondwana is recognized today as Africa, South America, Australia, Antarctica, the Indian subcontinent, and the Arabian Peninsula.

While abelisaurids were generally similar to T-rexes with shorter stubby arms, they had an unusually short, deep skull that often gave rise to crests, bumps, and horns.

When Tyrannosaurus and its relatives roamed North America and Asia, abelisaurids occupied a similar niche in Patagonia and other areas of South America.

Abelisaurids had large jaws. Like the T-Rex, they relied on them to crush and kill prey.

But abelisaurids also had smaller arms than tyrannosaurs.

The new species is a type of abelisaurid, small-armed dinosaur that thrived in the ancient southern supercontinent Gondwana.

Abelisaurids were the dominant predators in the Southern Hemisphere, around the same time that tyrannosaurids roamed North America and Asia.

They were part of a broader theropod clade of largely bipedal meat eaters with sharp grasping claws.

While abelisaurids were generally similar to T-rexes with shorter stubby arms, they had an unusually short, deep skull that often gave rise to crests, bumps, and horns.

Paleontologists first found an isolated theropod pelvis during excavations in 2002, before many further discoveries of bones.

Dr Fabiano Vidoi Iori of the Museu di Paleontology said: ‘The bones that were found were the pelvic bone, three vertebrae, and some that we have not yet identified.

‘A phylogenetic analysis was done with those (fragments), which then identified what species the animal belonged to, and allowed us to see that it was a new animal.’

The researchers also looked at whether the bones had traces of trampling, abrasion, weathering, or teeth.

Their findings suggest that the dinosaur’s body remained on the Earth’s surface for a short time before eventually being buried.

There were also no scratch marks, which means that Kurupi Itata’s bones did not move far from where she died where they were found.

The size of the pelvic girdle suggested it was a medium-sized abelisaurid, the researchers said.

He said the dinosaur’s muscular connectivity and bone anatomy also indicated that it was well adapted to running.

Its remains were found in Monte Alto (pictured), a municipality in the state of So Paulo that is one of Brazil's richest sites for dinosaur discoveries.

‘It is possible to infer that such muscles were stronger in the kurupi, and may have given the species the ability to cover a large area in search of prey and water in the hostile landscape of the Maastrichtian in the Marilia Formation,’ the authors wrote. paper.

He said the species lived in arid environments with little rainfall, as well as pterosaurids crocodyliforms – dog-like carnivores that were diverse and abundant on Gondwanan lands during the Cretaceous period.

The name Kurupi refers to a great demon of Guarani indigenous culture, the god of fertility and sexuality, the researchers said.

They wrote in their paper, ‘The choice of name is due to the fact that the fossils were found in the area of ​​”Motel Paraiso” (“Paradise Motel”), a place for intimate encounters.

Itata comes from the indigenous language Tupi and has two roots: ita for rock and attu for hard, referring to the very cemented rocks of the Marilia Formation in the Monte Alto regions.

A model of Kurupi Itata will now be on display at the Museum of Paleontology in Monte Alto.

Earlier this week it was revealed that a 29-foot-long dinosaur was one of two recently discovered species that roamed the Isle of Wight 125 million years ago.

Remains of carnivorous reptiles, about the same length as Stegosaurus but with crocodile-like skulls, were found on the beach near Brigstone on the island.

The pair were identified as a new, previously undescribed dinosaur species by paleontologists from the University of Southampton.

This new discovery of ugly Itata is described in Journal of South American Earth Sciences.
