Megalodon (/ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon)，意为“巨大牙齿”，是一种已经灭绝的鲭鱼型鲨鱼物种，生活在大约230万至360万年前的始新世至中新世时期。过去曾被认为属于鲭科（Lamnidae）并与大白鲨（Carcharodon carcharias）关系密切。但如今被归入已灭绝的 Otodontidae 科，该科在白鲨（大白鲨）出现的早白垩纪时期就已分化出来。

尽管被视为有史以来最强大、最具威胁性的掠食者之一，Megaldon 的化石证据仅碎片化，其外形和最大体型仍不确定。科学家对它更像是大白鲨的更结实版、鲸鲨（Rhincodon typus）、巨口鲨（Cetorhinus maximus）还是沙虎鲨（Carcharias taurus）等，意见不一。最近的估算给出误差最小的最大体长约为 20.3 米（67 英尺），体重可达约 103 公吨（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)
