Megaraptor

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.
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.

About Megaraptor:

Megaraptor was a large theropod of the Cretaceous Period, 84 to 65 mya.
Megaraptors possessed strong arms that wielded sickle-like claws that could inflict fatal wounds on prey, along with a more lightly built skull and jaws studded with smaller teeth.
They also had air-filled, bird-like bones.
Megaraptor was about 25–26 feet (7.5–8 meters) long.
Incomplete Megaraptor remains were found in 1996 in Northwest Patagonia, Argentina, by paleontologist Fernando E. Novas. Novas named it in 1998.
