Odontaspis aculeatus (Cappetta and Case)
aka Hypotodus aculeatus

Age - Cretaceous  Commonality -  Uncommon

  The teeth of Odontaspis aculeatus are awesome looking when found intact. These teeth are small, with a maximum size of about 1/2 inch. The anterior teeth posse a pair of cusplets, the larger being nearly half the length of the crown. he secondary cusplets are about one half the length of the primary cusps. The crown is narrow and dagger like. Lateral teeth usually have a third cusplet and a slightly more robust crown. The long slender cusplets make these teeth unique. Unfortunately, their delicate structure also makes these teeth very prone to breakage, and finding one intact is very uncommon.
