来自印度尼西亚爪哇，Cikalong 的正品巨齿鲨牙
高质量的巨齿鲨牙，尖端、锯齿和珐琅质完好，

巨齿鲨（Megalodon，/ˈmɛɡələdɒn/ MEG-əl-ə-don；Otodus megalodon），意为“巨牙”，是一种已灭绝的鲭鱼叉头鲨，生活在大约2300万年前至360万年前的始新世到中新世之间。
此前被认为属于鲭科（Lamnidae）的成员，与大白鲨（Carcharodon carcharias）有密切关系。然而，现在它被归入已灭绝的 Otodontidae 家族，该家族在早白垩纪就与大白鲨分化。

尽管被认为是有史以来最大、最强大的掠食者之一，巨齿鲨仅知于零散的遗骸，其外形和最大体型尚不确定。
科学家对于它更像是大白鲨的健壮版本、鲸鲨（Rhincodon typus）、巨鲨睡鲨（basking shark）Cetorhinus maximus 还是沙虎鲨（Carcharias taurus）之间存在分歧。
最新且误差最小的估计表明，最大身长可达20.3米（67英尺），体重可达103公吨（114短吨）

长度 10.0 cm

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)
