真实的 Carcharocles megalodon 牙齿，来自印度尼西亚，日惹，Cikalong

Megalodon (/ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon)，意为“巨牙”，是一种已灭绝的鲭鲨科鲨鱼，生活在大约 23 到 360 万年前的始新世至中新世时期。它曾被认为是 Lamnidae 科的一员，与大白鲨（Carcharodon carcharias）关系密切。但现在已归入已灭绝的 Otodontidae 家族，该家族在早白垩世就已与大白鲨分道扬镳。

尽管被视为有史以来最大、最强大的掠食者之一，Megaldon 的证据仅限断代性遗骸，其外形和最大体型仍不确定。科学家对其外观的推测有分歧：它是否更像大白鲨的结实版、鲸鲨（Rhincodon typus）、巨口鲨（Cetorhinus maximus）或沙虎鲨（Carcharias taurus）的样子。最新的、误差范围最小的估计显示，最大长度可达约 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 



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)
