Obisospinus (SciiFii)

Obisospinus crassurursus is a species of spinosaurid that originally did not exist, but has since been created by SciiFii as part of the agreement from AZA (Association of Zoos & Aquariums) to include various former extinct species (including Triceratops, etc) and SciiFii's original creations (including clawed unicorns) to the zoos and safari parks worldwide. Unlike Spinosaurus californicus, the African tiamat, or the South American tiamat, the Obisospinus lacks a fin on its tail due to SciiFii wanting to create a species of spinosaurid that resembles a pre-2014 Spinosaurus. But due to the lack of fin on its tail, Obisospinus doesn't swim as well or often as Spinosaurus and instead spends more time on land, only coming to the waters to either drink or hunt at the very shallow waters rather than swimming often as a result of its finless tail. Uniquely among spinosaurs, the Obisospinus has a fatty hump on its back rather than a sail, allowing it to store food to survive for several months without food, and a month without water. The Obisospinus is a very large animal, growing to be about the size of a Spinosaurus. It is a carnivore that normally feeds on carrion, fish, and crustaceans. It is a solitary animal in most of its life except during breeding seasons, when males attempt to find females to mate with.
