Summary
| Description |
English: Cosmopolitodus hastalis (Agassiz, 1843) - fossil shark tooth (lateral view; labial side below & lingual side above) from the Tertiary of eastern America.
Also known as Carcharodon hastalis. This shark tooth is from an extinct species known as the big-tooth mako shark. Like all sharks, the skeleton was cartilaginous, and the only commonly preserved fossil remains are teeth. Fossil remains of Cosmopolitodus hastalis are widespread in marine deposits of late Tertiary age. Their diet included marine mammals such as cetaceans. Classification: Animalia, Chordata, Vertebrata, Chondrichthyes, Elasmobranchii, Lamniformes, Carcharodontidae (or Lamnidae) Stratigraphy: unrecorded Miocene or Pliocene unit Locality: unrecorded/undisclosed site probably in the Chesapeake Bay region of eastern America See info. at: en.wikipedia.org/wiki/Cosmopolitodus |
