来自印度尼西亚爪哇，Cikalong 的正宗巨牙鲨 Megalodon（Carcharocles megalodon）牙齿

Quality Megalodon Tooth，牙尖良好，具锯齿和珐琅质

Megalodon (/ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon)，意为“巨牙”，是一种已灭绝的鲭鲨科鲨鱼，生活在约230万至360万年前的始中新世到上新世期间。它曾被认为属于头骨鲨科，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与大白鲨分道合流。

尽管被认为是史上最大、最强力的捕食者之一，巨牙鲨的只有断片状遗骸可知，其外形和最大体长仍不确定。科学家对其外形的看法各异，可能更像是大白鲨的结实版本、鲸鲨（Rhincodon typus）、鲸鲨属鲨鱼，或砂虎鲨（Carcharias taurus）。最新的、误差范围最小的估计显示，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)
