来自印度尼西亚爪哇，Cikalong 的正宗巨齿鲨（Carcharocles megalodon）牙齿

高质量的巨齿鲨牙齿，齿尖锯齿状良好，釉质完好，

巨齿鲨（Megalodon /ˈmɛɡələdɒn/ MEG-əl-ə-don；Otodus megalodon），意为“巨大牙齿”，是一种已灭绝的鲭鲨目动物，生活在大约230万到360万年前（中新世早期至上新世时期）。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 家族，该科在早白垩纪时期与大白鲨分化。

尽管被视为史上最大、最强大的捕食者之一，巨齿鲨仅以碎片化的遗骸为人所知，它的外貌和最大体型仍不确定。科学家对于它更像大白鲨的矮胖版、鲸鲨（Rhincodon typus）、鲸鲨寄生的北极鲨（Cetorhinus maximus）还是菜牙鲨（Carcharias taurus）各有不同看法。最近的估计给出的误差范围最小，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  serrations tip , 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)
