The world of Jurassic Park has expanded both in canon and not. The original trilogy was something to behold as it introduced dinosaurs like the T-Rex, Velociraptor and Spinosaurus.

But one of the most interesting things that the non-canon stories had done was introduce fascinating dinosaurs that never made it to the big screen, like the deadly Elaphrosaurus.
