A unique head spike and fish-eating jaws help make sense of these dinosaurs.
The Spinosaurus is a sail-backed, crocodile-snouted dinosaur that Hollywood depicted as a giant terrestrial predator capable of taking down a T. rex in Jurassic Park 3. Then they changed their mind and made it a fully aquatic diver in Jurassic World Rebirth—a rendering that was more in line with the latest paleontological knowledge.
But now, deep in the Sahara Desert, a team of researchers led by Paul C. Sereno, a paleontologist at the University of Chicago, discovered new Spinosaurus fossils suggesting both scientists and filmmakers might have got it all wrong again. The Spinosaurus most likely wasn’t an aquatic diver because, apparently, it couldn’t dive.
Bones in the sand
While the T. rex-beating version of the Spinosaurus was considered unlikely due to its relatively fragile skull, the newer depiction as an aquatic diver made more sense in light of paleontological evidence. Until now, all remains of these predators were pulled from coastal deposits near ancient seas and oceans. That geographic distribution was consistent with the aquatic lifestyle interpretation. If a creature lived on the coast, maybe it swam out to sea like a prehistoric seal, only crawling out to the beaches to rest just as it was depicted in Jurassic World Rebirth.
