However … Read more

Phuwiangvenator was named alongside another theropod dinosaur called Vayuraptor, also present in the Sao Khua Formation. Care should be taken not to confuse Phuwiangvenator with Phuwiangosaurus, a titanosaurian dinosaur known from the same formation as … Read more

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 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
