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]] and [[Africa]] == Description == [[File:Spinosauridae_Size_Diagram_by_PaleoGeek_-_Version_2.svg|350px|thumb|left|Size comparison of various spinosaurids with a human]] Spinosaurids had longer arms than most [[theropods]], the claw on the first finger was usually the largest. They evolved jaws like those of [[crocodile]]s, and their teeth were lo
