In Depth A very exciting find, the juvenile specimen of Rapetosaurus is to date the most complete titanosaurid skeleton ever found. This has allowed many of the gaps in the understanding of these dinosaurs to be filled in, including how the titanosaurs fit in among the sauropod group. This new understanding of titanosaur morphology has … Read more
In Depth Gobipteryx is a genus of enantiornithine that lived in Mongolia during the late Cretaceous. Studies of Gobipteryx show that Gobipteryx would have been capable of flight soon after hatching out from the egg. This would have given Gobipteryx a significant survival advantage in a world heavily populated by small theropod dinosaurs. Studies of … Read more

August Smith, … Read more
