Megalodon (/ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon)，意思是"巨大牙齿"，是一种已灭绝的鲭鲨科鲨鱼，生活在大约230万到360万年前（Mya），从早中新世到新近纪时期。它曾被认为属于 Lamnidae 家族，与大白鲨（Carcharodon carcharias）关系密切。然而，现在它被归入已灭绝的 Otodontidae 家族，该家族在早白垩纪就已与大白鲨分化。

尽管被认为是有史以来最大的、最强大的掠食者之一，巨齿鲨只是以零散的遗骸为人所知，其外貌和最大体长仍不确定。科学家对它更像大白鲨的健壮版本、鲸鲨（Rhincodon typus）、还是沙虎鲨（Carcharias taurus）存在分歧。最近的估计在误差范围最小的前提下，最大长度可达20.3米（67英尺），体重可达约103吨（114短吨）

Authentic Carcharocles megalodon tooth from Indonesia, Java , Cikalong 

Quality Megalodon Tooth, with good tip, serrations , and enamel, 

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)
