Rhinoptera bonasus (cownose stingray teeth & mouthparts) 1

Description:

Rhinoptera bonasus (Mitchill, 1815) - cownose stingray teeth & skeletal mouthparts (public display, Greater Cleveland Aquarium, Cleveland, Ohio, USA). I've seen fossil stingray teeth several times, but never understood them until now. The aquarium display shown above is the skeletal mouth remains of a modern cownose stingray. Stingray teeth consist of interlocking bars that crush food. Classification: Animalia, Chordata, Vertebrata, Chondrichthyes, Elasmobranchii, Myliobatidae See info. at: en.wikipedia.org/wiki/Cownose_ray
