Dinosaurs 'survived Jurassic era'

Dinosaur fossils found in Patagonia provide the first evidence long-necked diplodocid sauropods survived beyond the Jurassic period, when they were thought to have gone extinct.

Argentine paleontologist Pablo Gallina, a researcher at Buenos Aires’ Maimonides University, described the find as the first definitive evidence that diplodocids reached South America, and the most recent geologic record of this branch of sauropod anywhere.
