来自印度尼西亚爪哇，Cikalong 的正品巨齿鲨牙

高质量巨齿鲨牙，尖端、锯齿和珐琅质完好，

巨齿鲨（/ˈmɛɡələdɒn/ MEG-əl-ə-don； Otodus megalodon），意为“巨大之牙”，是一种已灭绝的鲭鲨科鱼类，生活在大约2300万至360万年前，即中新世早期至上新世之间。曾被认为属于鲭鲨科，与大白鲨（Carcharodon carcharias）有密切关系。然而现在归入已灭绝的 Otodontidae 家族，该科在早白垩纪时期便与大白鲨分化。

尽管被认为是有史以来最大和最强大的掠食者之一，巨齿鲨仅以碎片化化石为人所知，其外观和最大体型仍不确定。科学家们对于它更接近大白鲨的矮胖版、鲸鲨（Rhincodon typus）、抚鳞鲨（Cetorhinus maximus）还是沙虎鲨（Carcharias taurus）之间的形态存在分歧。最近且误差范围最小的估算给出最大长度约为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  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)
