来自印尼，爪哇，Cikalong 的正品 Carcharocles megalodon 牙齿

优质的巨齿鲨牙，牙尖、锯齿和釉质完好

Megalodon (/ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon), 意为“巨牙”，是一种已灭绝的鲭鲨科成员，生活在大约230万到360万年前（早中新世至晚中新世）。此前曾被认为属于 Lamnidae 家族，与大白鲨（Carcharodon carcharias）关系密切；但现今被归入已灭绝的 Otodontidae 家族，该家族在早白垩纪就已与大白鲨分化。

尽管被认为是有史以来最大、最强的掠食者之一，巨齿鲨仅有零散化石证据可知，其外形和最大体长仍不确定。科学家对于它更像大白鲨的魁梧版本、鲸鲨（Rhincodon typus）、抚慰鲨（Cetorhinus maximus）或沙虎鲨（Carcharias taurus）等哪一类存在分歧。最近的估计在误差范围最小的情况下，最大体长约为20.3米（67英尺），体重可达103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)
