SPINOSAURUS Spinosaurus aegyptiacus theropod spinosaurid dinosaur, depicted in Jurassic Park, which lived in what is now North Africa from the Lower Albiense to the Lower Cenomanian of the Cretaceous period, approximately 112 to 93, 5 million years ago. The current camel has a remembrance for its hump since it possessed a protrusion almost all along the spine, with short front legs and that rested on the hind ones while it was upright.
