GENEVA — Scientists have found the remains of four species of dinosaurs, including a megaraptor, in an inhospitable valley in Chilean Patagonia that has emerged over the past decade as an important fossil deposit, researchers said Wednesday (Jan 11).
The fossils were found in Cerro Guido, in southern Chile's Las Chinas valley near the border with Argentina, and taken to a laboratory in 2021. The researchers said they belong to dinosaurs that have not previously been identified in the area.
These carnivorous dinosaurs had raptor claws, small teeth for tearing, and large upper limbs which, according to the research, put them at the top of the food chain in the region, which they inhabited between 66 and 75 million years ago, at the end of the Cretaceous period. They also identified two specimens of Unenlagiinae, closely related to velociraptors and which have a"novel evolutionary character, which would indicate that this is a new species of unenlagine or perhaps a representative of a different clade ," said Dr Amudeo.
