However, the generic name was coined by Othniel Charles Marsh in 1878 due to the double-beamed chevron bones located in the underside of the tail that was considered the distinctive attribute that separates them from other dinosaurs. Further, the genus of Diplodocus fossils lived in Mid-western North America at the end of the Jurassic period. After thorough research, we found that the Dinosaurs lived between 154 and 152 million years ago, around the late Kimmeridgian Age. Diplodocus dinosaurs...

The genus Chasmosaurus translates to Chasm Lizard, Dinosaur in reference to the two large holes called fenestrae in its frills. Chasmosaurus fossils belong to the ceratopsian dinosaur that lived between 76.5 and 75.5 million years ago during the Late Cretaceous period. The distinguishing fenestrae are present in almost all ceratopsians but are particularly large in Chasmosaurus. It is referred to as a prehistoric beast because it measured 16-26 feet long from...
