来自印尼爪哇，Cikalong 的正宗巨齿鲨 Megalodon 牙齿

高质量的 Megalodon 牙齿，尖端、锯齿和牙釉质完好

Megalodon (/ˈmɛɡələdɒn/ MEG-əl-ə-don；Otodus megalodon)，意为“巨齿”，是一种已灭绝的鲭鲨科鲨鱼，生活在约 2300 万到 360 万年前的始新世至中新世。它曾被认为属于 Lampnidae 科，与大白鲨（Carcharodon carcharias）关系密切。但现在被归入已灭绝的 Otodontidae 科，该科在早白垩纪就已与大白鲨分化。

尽管被认为是迄今为止体型最大的掠食者之一， Megalodon 的证据仅为碎片化遗骸，其外观和最大体型仍不确定。科学家对它更像大白鲨的更矮胖版本、鲸鲨（Rhincodon typus）、鲸鲨或沙虎鲨（Carcharias taurus）谁更接近存在分歧。最近的估算给出的最大长度在 20.3 米（约 67 英尺），体重可达 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)
