| 説明 | Carcharodon megalodon Agassiz, 1843 - fossil shark tooth from the Tertiary of offshore-North Carolina, USA. (facial side; ~8.1 centimeters across at its widest; collected by "The Fossil Exchange" divers)Carcharodon megalodon is an extinct giant white shark (also known as the megatooth shark). Like all sharks, the skeleton was cartilaginous, and the only commonly preserved fossil remains are teeth. The teeth of this ancient giant shark had serrated edges, which function to readily slice through flesh. Estimates of original body size vary from 12 meters to over 35 meters long. Fossil remains of Carcharodon megalodon are widespread in inferred warm-water marine deposits of Miocene and Pliocene age. Considering the size of megatooth sharks, their diet is considered to have principally consisted of whales (shark tooth marks on fossil whale bones are not uncommon).Stratigraphy: Yorktown Formation, Upper Miocene to Lower PlioceneClassification: Animalia, Chordata, Vertebrata, Chondrichthyes, Elasmobranchii, Lamniformes, Carcharodontidae (or Lamnidae, or Otodontidae)Locality: "deep water ledges 45 miles offshore" from the coast of North Carolina, USA---------------------------See info. at:en.wikipedia.org/wiki/Megalodon |
