Bahariasaurus was a genus of large theropod dinosaur native to Late Cretaceous Africa. Its remains date from 95 million years ago, making it a probable contemporary of the slightly larger, unrelated theropods, Carcharodontosaurus and Spinosaurus. The type (and only) species is Bahariasaurus ingens

Deltadromeus agilisEdit

There is another african theropod that strongly resembles Bahariasaurus, its name is Deltadromeus. These two theropods resemble each other more than they do any other theropod, as their is little to nothing differenciating them other than things that are easily artibuted to individual variation. It is highly likely that Deltadromeus agilis is a junior synonym of Bahariasaurus ingens.


ClassificationEdit

Its fossils are very fragmentary; however its body can be based on reconstructions of its closest relatives, Elaphrosaurus and Limusaurus, as well as what is known of its likely synonym Deltadromeus. Although Elaphrosaurus and Bahariasaurus are not known from any skull material, and what is known is quite fragmentary, Limusaurus is known from two or possibly three very complete fossils allowing Elaphrosaurus and Bahariasaurus to be accuratly reconstructed.

Like Limusaurus and Elaphrosaurus, Bahariasaurus was a basal Ceratosaur, although it has in the past been classified as a Carcharodontosaurid and Tyrannosauroid, aswell as Deltadromeus previously being classified as a Ceolurosaur and a Noasaurid.

DescriptionEdit

Largest Theropods 2.1

A size comparison of the top 5 largest Theropod Dinosaurs with Bahariasaurus in light blue.

Based on Limusaurus and Elaphrosaurus, Bahariasaurus would have possesed very long legs with leg proportions that were aimed at running fast. Its femur was of a modest length, however, its tibia was very large particulary compared to the femur. This is a trait of fast running animals indicating that Bahariasaurus was a fast runner. Its arms, by comparison, were very small.

Bahariasaurus was a very large theropod. Based on the femur length of two specimens previously atributed to Deltadromeus, it is possible to calculate the full length. The holotype specimen of Deltadromeus measured 8m in length with a 74cm long femur. A larger femur measures 122cm in length. The animal that this femur belonged to would, if in the same proportion as the type specimen, have measured a full less than 13m when alive and would have weighed around 5 to 5.5t.
