Instead, the movie is a dry documentary about the discovery, in a desolate corner of the American West, of a very old, very little and very unimpressive dinosaur called chindesaurus.
It is described as most closely related to the earlier " Lagerpeton " of Argentina, but was found among remains of true dinosaurs like " Chindesaurus ", indicating that the first dinosaurs did not immediately replace related groups.
Examination of this genus by Sues et al . ( 2011 ) demonstrates that " Daemonosaurus " is separate and distinct from its other contemporaries . " Daemonosaurus " differs from " Herrerasaurus " based on key features in the skull and because it has much larger teeth in the premaxilla . " Daemonosaurus " differs from " Eodromaeus " based on features of the jaw bone, skull, cheek bones, and because it has much larger teeth in the premaxilla . " Daemonosaurus " differs from " Eoraptor " lunensis based on the presence of much larger premaxillary and anterior maxillary teeth and a much more restricted Tawa hallae " and " Coelophysis " bauri in features of the skull bones . " Daemonosaurus " differs from " Chindesaurus " bryansmalli in features of the cervical vertebrae.
