来自印度尼西亚爪哇岛，Cikalong 的正品巨齿鲨牙齿

优质巨齿鲨牙，尖端、锯齿和珐琅质状况良好，

巨齿鲨（/ˈmɛɡələdɒn/ MEG-əl-ə-don；Otodus megalodon），意为“巨牙”，是一种已灭绝的鲭鲨科鲭鲨目物种，生活在大约2300万年前至360万年前的始新世晚期至中新世时期。它曾被认为属于 Laminidae 家族，并且与大白鲨（Carcharodon carcharias）关系密切。然而，现今被归入已灭绝的 Otodontidae 家族，该家族在早白垩纪就已与大白鲨分化。

尽管被视为有史以来最大、最强力的掠食者之一，巨齿鲨仅以断片性遗骸为人所知，其外观和最大体型仍不确定。科学家对于它更接近大白鲨的矮胖型、鲸鲨（Rhincodon typus）、沼鳃鲨（Cetorhinus maximus）或沙虎鲨（Carcharias taurus）等哪一类，存在分歧。最近的估算在最小误差范围内给出的最大长度约为20.3米（67英尺），体重可达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)
