来自印尼爪哇岛 Cikalong 的正品巨齿鲨牙齿（Carcharocles megalodon）

品质巨齿鲨牙，尖端完好，齿锯齿与牙釉质完好，

巨齿鲨（Megalodon /ˈmɛɡələdɒn/，发音 MEG-əl-ə-don；Otodus megalodon），意为“巨牙”，是一种已灭绝的鲭科鲨鱼，生活在大约2300万年前至360万年前的始新世至上新世期间。它曾被认为属于鳐科，且是大白鲨（Carcharodon carcharias）的近亲。然而现在它被归入已灭绝的 Otodontidae 科，该科在早白垩纪便与大白鲨分道扬镳。

尽管被视为有史以来最大、最强大的掠食者之一，巨齿鲨仅以零散的化石残存为人所知，其外形和最大体型仍不确定。科学家们对于它更可能长成大白鲨的结实版本、抹香鲸（Rhincodon typus）、魟鲨（Cetorhinus maximus）还是沙虎鲨（Carcharias taurus）的模样存在分歧。最近且误差范围最小的估算显示，其最大身长可达约20.3米（67英尺），体重约103吨（114短吨）。

长度 11.7 cm

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)
