来自印度尼西亚，爪哇，Cikalong 的正品巨齿鲨牙

优质巨齿鲨牙，牙尖完好，锯齿和琺银质光泽良好，

巨齿鲨（/ˈmɛɡələdɒn/ MEG-əl-ə-don；Otodus megalodon），意为“巨牙”，是灭绝的鲭鲨科鲨鱼物种，生活在约2300万年前到360万年前（Mya），跨越中新世早期至上新世时期。过去曾被认为属于 Lamnidae 家族，与大白鲨（Carcharodon carcharias）有密切亲缘关系；然而现今被归类于灭绝的 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、最强大的掠食者之一，巨齿鲨的证据仅以零碎遗骸为据，其外貌与最大体型仍不确定。科学家对其外观的猜测不一，可能更像大白鲨的更粗壮版本、鲸鲨（Rhincodon typus）、抚鲸鲨（Cetorhinus maximus）或沙虎鲨（Carcharias taurus）。最近且误差最小的估计显示其最大体长可达约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)
