来自印尼爪哇岛 Cikalong 的正宗 Megalodon 牙齿

品质 Megalodon 牙齿，附有良好的尖端、锯齿和牙釉质

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 2300 万到 360 万年前的新近纪早期至上新世时期。它曾被认为属于 Lamnidae 家族，与大白鲨(Carcharodon carcharias)关系密切。然而，现在被归入已灭绝的 Otodontidae 科，该科在早白垩纪时与大白鲨分道扬镳。

尽管被认为是有史以来最大的、最强大的掠食者之一，Megaldon 的化石仅存片段，其外形与最大尺寸仍不确定。科学家对它更像是大白鲨的矮胖版、鲸鲨(Rhincodon typus)、柬鲨(Cetorhinus maximus)还是沙虎鲨(Carcharias taurus)存在分歧。最新且误差最小的估计显示，其最大长度可达约 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 

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)
