Paleontological PSA about Jurassic World: The Mosasaurus is not a
dinosaur. It lived at the same time as dinosaurs but it is more closely
related to monitor lizards. Nor are the winged reptiles dinosaurs, or
are they pterodactyls (incidentally also not a dinosaur). They are
Pteranodon and Dimorphodon, both of which fall into a group of winged
reptiles called Pterosaurs, to which the family Pterodacyl and the name
sake Pterodactylus also belong.
