Nationalgeographic.co.id—Paleontologists have reported a new genus and species of titan dinosaur from the giant colossosaurian group. The new species was identified from fossils found in Patagonia, Argentina.
This newly identified species lived in what is now Patagonia, a region of Argentina during the Late Cretaceous, between 95 and 93 million years ago.
Discovery Chucarosaurus to be snatched reported in a paper in the journal Cretaceous Research under the title “A new gigant titanosaur (Dinosauria, Sauropoda) from the Upper Cretaceous of Northwestern Patagonia, Argentina.”
This new titan dinosaur is named Chucarosaurus to be snatchedit was a large sauropod with relatively slender fore and hind limbs.
Chucarosaurus to be snatched belongs to the Colossosauria group, a group of titanosaurian sauropods from the Early to Late Cretaceous in South America.
Colossosauria was a clade of titanic sauropod dinosaurs from the Late Cretaceous (Cretaceous) through Late Cretaceous South America. The group was originally named in 2019 and is defined as the “most inclusive clade”.
“Titanosaurs or titan dinosaurs were the most diverse and abundant terrestrial herbivores on the mainland of the Southern Hemisphere during the Late Cretaceous,” said Federico Agnolin.

“They are widely distributed globally, and more than 60 valid species are known from South America.”
Titanosaurus is a large clade of sauropod dinosaurs whose members include and are common to most Cretaceous terrestrial ecosystems.
He explained that Titanosaurus was confined to the Cretaceous Age and was the most common dinosaur found in the Upper Cretaceous layers of South America, particularly in Patagonia.
“A special aspect of paleobiogeography is its high diversity during the last Cretaceous period rivaling hadrosaurids and ceratopsid ornithischians in Northern Hemisphere ecosystems at the same time,” he says.
