context_page_description: Deinonychus was a medium theropod dinosaur. It was a dromaeosaur, and also a larger relative of the famous Velociraptor. This 3.4 meter long Deinonychus lived during the Lower Cretaceous, about 115-108 million years ago. Fossils have been found in the U.S. states of Montana, Wyoming, and Oklahoma.
  Deinonychus is perhaps the single most important dinosaur discovered in the mid 20th century.
