The extinct shark #Ptychodus had amazing "tiles" for teeth; they abutted one another inside the jaw, enabling the shark to eat hard prey, likely shelled mollusks. These bony tooth nodules had ridges for grip, central bumps (probably) for pressure points to crush shells, and were also quite beautiful to look at! @nhmu #paleontology #scicomm #science #usofscience #biology #zoology #geology #fossil #fossils #elasmobranchology #nhmu #naturalhistorymuseum #naturalhistorymuseumofutah #utah #saltlakecity #shark #sharks #marinebiology (at Natural History Museum of Utah) https://www.instagram.com/p/BpyQBwkgJVv/?utm_source=ig_tumblr_share&igshid=suojy5d981ce
