What region is bordered by the Andes Mountains, the Colorado River and the Atlantic Ocean? Balkan Peninsula, Amazon Basin, Patagonia or Western Plateau. The only option here that's surrounded by all these features is Patagonia, a region in Argentina.
If you thought dinosaur names peaked with Titanasaurs. Let's talk about ninjatitan. It sounds so big and stealthy at the same time. Ninjatitan zapatai is what researchers are calling some fossils recently found in Argentina. The skeleton is incomplete and there's a lot that's still unknown about this animal.
But paleontologists believe that ninjatitans were sauropods with bodies like brontosaurus. Think long necks, thick legs and the length of about 65 feet. They're not the biggest titanosaurs. One of them named argentinasaurs is thought to have been as long as 115 feet.
But scientists say the recently discovered fossils are older than those of other types of titanosaurs and that suggests that ninjatitans might have pre-dated other dinosaurs that looked like them. The region of Patagonia in southern Argentina has been an epicenter of dino discoveries.
