context_page_description: Spinosauridae is a family of carnivorous theropod dinosaurs from the Jurassic and Cretaceous periods. They are unique among other meat-eating dinosaurs from their more water-based lifestyle, which involved a diet of mostly fish. Spinosaurid fossils have been found all over the world, including Asia, South America, Europe, Africa, and Australia.
context_section_description: The family "Spinosauridae" was named by the German paleontologist Ernst Stromer in 1915, he was the one that discovered the first genus in the group, Spinosaurus. And as scientists discovered more fossils of its close relatives, the family was eventually split into two subfamilies: Baryonychinae, and Spinosaurinae. This was done because of differences in the anatomy of their skulls and teeth.
  This is a cladogram made in 2017 showing the relationships between different spinosaurids inside of megalosauroidea.
