Remains Of Dinosaurs Species:
Scientists have found the remains of four species of dinosaurs, including a megaraptor, in an inhospitable valley in Chilean Patagonia for the first time.
- 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.
- The Cretaceous Period, in geologic time, is the last of the three periods of the Mesozoic Era.
- The Cretaceous began 145.0 million years ago and ended 66 million years ago.
- It followed the Jurassic Period and was succeeded by the Paleogene Period.
