150 million years ago during the Late Jurassic Period, Ostafrikasaurus crassiserratus prowls the semitropical savannas of what will one day become the East African country of Tanzania. Known only from a few fossilized teeth, Ostafrikasaurus appears to have been a relatively small, primitive member of the spinosaurid family, the same family of fish-eating theropod dinosaurs as the better-known Spinosaurus and Baryonyx. However, the serrated blade-like character of its teeth, in sharp contrast to the smoother and more conical dentition of its Cretaceous successors, suggests that Ostafrikasaurus had yet to complete the evolutionary transition to specialized piscivory.
