An article published in the journal “Royal Society Open Science” describes the study of a dinosaur called Zuul crurivastator that lived about 75 million years ago in today’s Montana, USA. It’s an Anchilosaurus, a group of armored herbivores that appeared during the Jurassic period that lived until the end of the Cretaceous. The name Zuul is inspired by the monster of the movie “Ghostbusters” because the discoverers saw some similarities with it.
