Carcharodon
megalodon
Carcharodon megalodon (fondly referred to as “meg” by fossil
shark lovers) was an extinct giant white shark (a.k.a. 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 >35
meters long.
Fossil remains of Carcharodon megalodon are
widespread in inferred warm-water marine deposits of Miocene & Pliocene
age. Considering the size of megatooth sharks, their diet is inferred to
have consisted principally of whales (shark tooth marks on fossil whale bones
are not uncommon).
Classification: Animalia, Chordata, Vertebrata, Chondrichthyes,
Elasmobranchii, Lamniformes, Carcharodontidae (or Lamnidae, or
Otodontidae)

Carcharodon megalodon Agassiz, 1843 tooth (centimeter scale) from the late
Cenozoic of eastern America. This specimen has a worn tooth tip
(apex) & some abraded serrations. This is the labial surface (facial
surface) of the tooth - the side facing outward. Labial surfaces of shark
teeth tend to be flattish. The opposite side, the lingual side (the side
facing the tongue) tends to be convex. The dark-colored lower quarter of
the tooth represents the root; everything above is the crown.
