Velociraptor Andrewsii

Velociraptor Andrewsii (name meaning Andew's fast thief) is an extinct wolf-sized non-avian theropod dinosaur part of the extinct group of theropods called Dromaeosaurids, which were related to Troodonts (which are still alive today). Velociraptor Andrewsii lived in what is now Mongolia and China during the early Cenozoic era from 64 million years ago to 44 million years ago. Their ancestors may have survived in a manner like what happened to the ancestors to modern Troodonts. They were fully carnivorous and most likely often preyed on Protoceratops Mourii as claw marks and teeth marks on some Protoceratops Mourii showed, and the fact that there's a famous fossil of a Cretaceous Velociraptor attacking a Protoceratops dating around 75 million years ago. Velociraptor Andrewsii was probably a social pack hunter, but was more likely a solitary hunter as modern Troodonts don't hunt together unless if they're mated pairs. It is unknown why Velociraptor Andrewsii became extinct in 44 million years ago, but it may have been due to competition for food from newly evolving mammal predators and/or not finding enough food due to food scarcity, especially since Protoceratops Mourii became extinct about a million years earlier.
