[Just for fun] Trex Vs Triceratops : The Most DISRESPECTFUL Dinosaur Fight Ever
In Depth Charruodon is a genus of cynodont that lived in South America during the Triassic. Further Reading - A new therioherpetid cynodont from the Santa Maria Formation (middle Late Triassic), southern Brazil. - Geodiversitas 22 (4). - F. Abdala & A. M. Ribeiro - 2000.
In Depth Like with Liaoningosaurus, Zhongyuansaurus was first described as a nodosaurid, but later identified as an ankylosaurid. Further study has identified Zhongyuansaurus as the most basal (primitive) ankylosaurine, the group of ankylosaurs that contains the more advance forms that began to appear as the Cretaceous progressed. So basal in fact was Zhongyuansaurus, that it … Read more
In Depth A relative of the gomphothere elephants, Stegomastodon along with Cuvieronius was one of only two known elephant genera to spread into South America (remains once considered to belong to the Mammut genus are now assigned to these two genera). Unlike other gomphothere elephants (those like Gomphotherium), Stegomastodon only had two tusks that grew … Read more
In Depth Mercuriceratops is a genus of chasmosaurine ceratopsian dinosaur that lived in North America during the Cretaceous. Unfortunately not much is known for certain about Mercuriceratops, however, it has been speculated to have been comparable to Chasmosaurus in size. Further Reading - A new chasmosaurine from northern Laramidia expands fill disparity in ceratopsid dinosaurs. … Read more
In Depth Like with many dinosaurs, the remains of Elaltitan were originally described as belonging to another genus. Originally assigned by Bonarparte and Gasparini to Antarctosaurus in 1979, the remains were later described as Argyrosaurus by Jaime Powell. Later study of the remains by Philip Mannion and Alejandro Otero led to several key differences being … Read more
In Depth Once considered a transitional form between archosaurs and lizards, palaeontologists are no longer as certain as they once were as to exactly how Prolacerta were related to these groups. One key observation is that the teeth are rooted deep and fused to the bones, and not loosely implanted like the teeth of known … Read more
In Depth Kukufeldia is a genus of ornithopod dinosaur that is known only from a partial jawbone. Most researchers have considered the genus to be a nomen dubium while others have proposed a synonymy with Barilium. Further Reading - A new basal iguanodont (Dinosauria: Ornithischia) from the Wealden (Lower Cretaceous) of England. - Zootaxa, 2569: … Read more
In Depth The broad range of fossils discovered around the world suggests that the bony fish Xiphactinus had a cosmopolitan distribution. A comparable similar fish with regards to appearance is the modern day Tarpon. Although Tarpon are not related to the ancient Xiphactinus, their streamlined bodies and strongly upturned mouths bear a striking resemblence. One … Read more
In Depth Polysternon is a genus of bothremydid turtle that is known to have lived in Western Europe during the latest stages of the Cretaceous. Further Reading - The youngest species of Polysternon: A new bothremydid turtle from the uppermost Maastrichtian of the southern Pyrenees. - Cretaceous Research 35: 133–142 - J. Marmi, �.H. Luj�n, … Read more
In Depth Caulkicephalus had to be reconstructed from several fragments before it could be classified. Once pieced together the form of an ornithocheirid pterosaur was easy to see including the specialised fish catching dentition. Although only the replacement teeth that are still within the jaw have been preserved, the size of the actual teeth can … Read more
