来自印度尼西亚 Java，Cikalong 的正宗巨齿鲨牙齿

高质量的巨齿鲨牙，尖端、锯齿和牙釉质均完好，

巨齿鲨（Megalodon /ˈmɛɡələdɒn/ MEG-əl-ə-don；Otodus megalodon），意为“巨牙”，是一种已灭绝的鲭形鲨鱼，生活在约2300万到360万年前的始新世至上新世时期。曾被认为属于狼鲨科，与大白鲨（Carcharodon carcharias）关系密切；但现归入已灭绝的 Otodontidae 家族，该家族在早白垩纪已与大白鲨分道。 

尽管被认为是有史以来最大、最强大的捕食者之一，巨齿鲨仅以零散遗骸知之，其外观和最大体型尚不确定。科学家对于其外形更接近大白鲨的矮胖版、鲸鲨（Rhincodon typus）、露背鲨（Cetorhinus maximus）还是沙虎鲨（Carcharias taurus）等说法不一。最近的估计在误差范围最小的情况下，最大体长可达约 20.3 米（67 英尺），体重可达约 103 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)
