A 200-million-year-old sharp-toothed fossil was found in the western part of the United States, according to Wednesday’s edition of British journal Proceedings of the Royal Society B.

According to Hans-Dieter Sues, curator of vertebrae paleontology of the Smithsonian’s National Museum of Natural History, the sharp-toothed fossil known as Daemonosaurus chauliodus in the Triassic era dinosaur,  has a short snout and slanting front teeth.

Sues explained that the fossil discovery may help in filling up the gap between the dinosaurs that lived in Argentina and Brazil about 230 million years ago and the later theropods that include Tyrannosaurus rex or more commonly known as TRex. He added that skull and neckof the Daemonosaurus shows its intermediary between early predatory dinosaurs and the later theropods.
