Dinosaur research

Dinosaur research has become very active in the 1970s. This was triggered, mostly by John Ostrom's discovery of Deinonychus, an active predator that may have been warm-blooded, in contrast to the extinct dinosaurs which were cold-blooded. Major new dinosaur discoveries have been made by paleontologists working in previously unexploited regions, including India, Madagascar, Antarctica, and in China where the well-preserved feathered dinosaurs in China have strengthen the link between dinosaurs and their descendants, modern birds.
