这颗牙齿经过修补和抛光。

巨齿鲨（/ˈmɛɡələdɒn/ MEG-əl-ə-don；Otodus megalodon），意为“大牙齿”，是一种已灭绝的鲭鲨，生活于约2300万至360万年前（百万年前），从早中新世到上新世。它曾被认为属于鼠鲨科，与大白鲨（Carcharodon carcharias）关系密切。然而，如今它被归入已灭绝的齿鲛科；该科在早白垩世时与大白鲨分化。

巨齿鲨被视为有史以来体型最大、力量最强的掠食者之一，但目前仅发现零星遗骸，因此其外形和最大体型仍不确定。科学家对于它究竟更像体型粗壮的大白鲨、鲸鲨（Rhincodon typus）、姥鲨（Cetorhinus maximus）还是虎鲨（Carcharias taurus），意见不一。误差范围最小的最新估算显示，其最大体长可达20.3米（67英尺），体重可达103公吨（114美吨）。

Megalodon (/ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon), meaning "big tooth", is an extinct species of mackerel shark that lived approximately 23 to 3.6 million years ago (Mya), from the Early Miocene to the Pliocene epochs. It was formerly thought to be a member of the family Lamnidae and a close relative of the great white shark (Carcharodon carcharias). However, it is now classified into the extinct family Otodontidae, which diverged from the great white shark during the Early Cretaceous.

While regarded as one of the largest and most powerful predators to have ever lived, the megalodon is only known from fragmentary remains, and its appearance and maximum size are uncertain. Scientists differ on whether it would have more closely resembled a stockier version of the great white shark, the whale shark (Rhincodon typus), the basking shark (Cetorhinus maximus) or the sand tiger shark (Carcharias taurus). The most recent estimate with the least error range suggests a maximum length estimate up to 20.3 meters (67 ft),  weighs up to 103 metric tons (114 short tons)
