@naturalhistorymuseum: 🖐️High five, anyone?? 🐬Eurhinodelphis longirostris, or the “true nosed dolphin,” is actually a toothed whale. It lived during the Miocene around 15 million years ago. Its teeth—sharp, pointed, and much more numerous than in most mammals—are similar to those of living porpoises, suggesting that, like them, it ate a diet of fish! #MuseumTok #STEM #cetaceans #naturalhistory #fossils
