来自印度尼西亚，爪哇，Cikalong 的正宗 Carcharocles megalodon 牙齿

高质量的巨齿鲨牙，尖端、锯齿和釉质完好，

巨齿鲨（Megalodon，发音 /ˈmɛɡələdɒn/，MEG-əl-ə-don；Otodus megalodon），意为“巨牙”，是一种已灭绝的鲭鱼鲨科鲨鱼，约在2300万年前至360万年前的晚中新世至上新世期间生存。此前被认为属于 Lamnidae 科，与大白鲨 (Carcharodon carcharias) 关系密切。然而，现在已归入已灭绝的 Otodontidae 科，与大白鲨在早白垩纪分道扬镳。

尽管被公认为有史以来最巨大、最强大的掠食者之一，但巨齿鲨仅从零碎的遗骸得知，其外形和最大体型仍不确定。科学家对于它更接近大白鲨的矮壮体型、鲸鲨（Rhincodon typus）、鸣沙鲨（basking shark，Cetorhinus maximus）或沙虎鲨（Carcharias taurus）之间存在分歧。最新的、误差范围最小的估计表明其最大体长可达约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)
