来自印尼，爪哇岛，Cikalong 的真实巨齿鲨牙齿

质量优良的巨齿鲨牙齿，尖端、锯齿和牙釉质完好

巨齿鲨（/ˈmɛɡələdɒn/ MEG-əl-ə-don； Otodus megalodon），意为“巨牙”，是一个已灭绝的鲭科鲨鱼，生活在大约2300万年前至360万年前的始新世至中新世。过去曾被认为属于狼鲨科，与大白鲨（Carcharodon carcharias）关系密切。然而现在被归入已灭绝的 Otodontidae 家族，该家族在早白垩纪就已从大白鲨分化出来。

尽管被视为有史以来最庞大、最强力的掠食者之一，巨齿鲨的化石仅存片段，外形和最大体型仍不确定。科学家对其外形的看法不一，可能更接近大白鲨的矮胖形、鲸鲨（Rhincodon typus）、大鳍鲨（Cetorhinus maximus）或沙虎鲨（Carcharias taurus）的形态。最近的估算给出的最大长度在 20.3 米（67 英尺）左右，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)
