The European Roots of Africa's Giant Predatory Dinosaurs

 From Phys.org:

Tyrannosaurus is perhaps the best-known bipedal predatory dinosaur—but not the largest known representative of this group: Spinosaurus occurred in Africa in the early Late Cretaceous period (about 95 million years ago) and was even larger, measuring up to 18 meters in length.

In collaboration with Spanish colleagues, Rauhut has now found new evidence that the gigantic spinosaurs had their roots in Europe. New finds and the re-examination of previously collected remains of the little-known predatory dinosaur Camarillasaurus cirugedae from the Lower Cretaceous period (about 128 million years ago) in Spain show that this species was a close relative of the giant North African spinosaurs.

Camarillasaurus was found in the central Spanish province of Teruel. The was originally classified as a ceratosaur—a group of predatory dinosaurs little known in Europe and whose occurrence in the Lower Cretaceous of Spain would represent a find "outside of space and time," as stated in the original publication. This interpretation was based on a few fragmentary remains described more than 10 years ago. (Read more.)
