来自印度尼西亚爪哇，Cikalong 的正品 Carcharocles megalodon 牙齿

Megalodon (/ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon)，意为“巨齿”，是一种已灭绝的鲭鲨科鲨鱼，约在2300万至360万年前的始新世至中新世时期生活过。它曾被认为是 Lamnidae 家族成员，与大白鲨（Carcharodon carcharias）关系密切。然而，现今被归类于已灭绝的 Otodontidae 家族，该科在早白垩纪就与大白鲨分道扬镳。

虽然被视为有史以来最大、最强大的掠食者之一，Megaldon 仅从碎片化遗骸得知，其外观和最大体长尚不确定。科学家对它更可能更像大白鲨的更粗壮版本、鲸鲨（Rhincodon typus）、露脊鲨（Cetorhinus maximus）还是沙虎鲨（Carcharias taurus）有不同看法。最新的估计在误差范围最小的情况下，最大体长可达约20.3米（67英尺），体重可达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)
