Fossils that Changed Dinosaur History: Mosasaurus


The remains of Mosasaurus were discovered well before educated society knew anything about evolution, dinosaurs, or marine reptiles--in a mine in Holland in the late 18th century (hence this creature's name, after the nearby Meuse river). The unearthing of these fossils led early naturalists like Georges Cuvier to speculate, for the first time, about the possibility that currently extinct species had once lived on earth, which flew in the face of accepted religious dogma of the time.
