In Depth Closely related to the massive predator Giganotosaurus, the discovery of seven Mapusaurus individuals in the same bone bed would question the notion that predatory dinosaurs were always solitary creatures. When the bone bed was excavated between 1997 and 2001, only the remains of Mapusaurus where found, and these individuals were all of different … Read more
In Depth Veterupristisaurus is a genus of carcharodontosaurid theropod dinosaur that lived in Africa during the late Jurassic. So far Veterupristisaurus is only known from a few vertebrae, but comparisons to Acrocanthosaurus have yielded an estimated range for the holotype individual of Veterupristisaurus of between eight and a half and ten meters in length. This … Read more
In Depth Sauropareion is a genus of small procolophonid reptile that lived in South Africa at the start of the Triassic period. Further Reading - A new Triassic procolophonoid reptile and its implications for procolophonoid survivorship during the Permo-Triassic extinction event. - Proceedings of the Royal Society B: Biological Sciences 268 (1480): 2047–2052. - Sean … Read more
In Depth Initially described from a tibia (one of the lower leg bones), a second discovery in 2007 revealed much more of the skeleton of Condorraptor, allowing for a clearer picture of Condorraptor to come to light. Condorraptor was a mid-sized theropod that may have been similar to the famous Megalosaurus, the first dinosaur genus … Read more
In Depth Eomurruna is a genus of procolophonid parareptile that lived in Australia during the late Triassic. The tooth pattern of Eomurruna shows no collision of the teeth, which is a trait seen in other procolophonids that are thought to have been herbivorous. Even as a plant eater however, there is still a possibility that … Read more
In Depth Kelmayisaurus is a genus of carcharodontosaurid dinosaur that lived in China during the early Cretaceous. Kelmayisaurus is currently only known by partial upper and lower jaws, and because of this the exact size of Kelmayisaurus is still unknown. There are still reports of a second species named K. “grandis” approaching sizes of up … Read more
In Depth As a macronarian sauropod, Tehuelchesaurus is thought to have had a body form better for reaching up to high growing vegetation rather than sweeping across a broad area to browse upon low growing vegetation like a diplodocid. Although only known from South America, Tehuelchesaurus is actually thought to be very similar in form … Read more
In Depth Phyllodontosuchus is a genus of sphenosuchian crocodile that lived in Asia during the early Jurassic. Phyllodontosuchus had a heterodont dentition, meaning that the shape of the teeth differed according to their position in the mouth. The first few teeth in the mouth were conical in a similar fashion to most other crocodylomorphs, but … Read more
In Depth Like with Saltasaurus, Maxakalisaurus is a titanosaur known to have had bony plates called osteoderms (scutes) in the skin for additional protection from harm. The post cranial skeleton of Maxakalisaurus also hints at a relationship to other aeolsaurid genera such as Aeolosaurus, Gondwanatitan. Maxakalisaurus is one of the largest dinosaurs known to have … Read more
