来自印度尼西亚爪哇，Cikalong 的正宗巨齿鲨牙齿

高质量的巨齿鲨牙齿，保留良好的锯齿、尖端和牙釉质

巨齿鲨（Carcharocles megalodon，/ˈmɛɡələdɒn/ MEG-əl-ə-don； Otodus megalodon），意为“巨大的牙齿”，是一个已灭绝的鲭鲨科鲨鱼，生活在大约230万至360万年前（从始新世到上新世）。它曾被认为属于 Lamnidae 科，是大白鲨（Carcharodon carcharias）的近亲。但现今被归入已灭绝的 Otodontidae 科，该科在早白垩纪时期就已与大白鲨分道。 

尽管被认为是有史以来最大、最强大的捕食者之一，巨齿鲨仅有零散的化石证据可考，其外形和最大体长尚不确定。科学家对于它更像大白鲨的结实版本、鲸鲨（Rhincodon typus）、抚鲸鲨（Cetorhinus maximus）或沙虎鲨（Carcharias taurus）哪一类尚有分歧。最近的估计在误差范围最小的情况下给出最大体长约为20.3米（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  serrations, tip , 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)
