This crocodile is based on a nameless crocodile found in Morocco
A crocodile was seen resting on a river bank until being scared off by a Spinosaurus into the river. Another was later seen resting on the bank of a lake during a drought where it encountered a Spinosaurus. Both of them were repelled by a Sarcosuchus which was disturbed during its hibernation.
After a juvenile Paralititan got stuck in a pit of mud, a bask of crocodiles emerged from a nearby river to bring down the struggling individual. However, as a Sarcosuchus also came for the Paralititan, the crocodiles retreated to the river.
