来自印度尼西亚爪哇，Cikalong 的正宗巨齿鲨牙

高质量的巨齿鲨牙，具备良好的锯齿和牙釉质，

巨齿鲨（Carcharocles megalodon）/ˈmɛɡələdɒn/ MEG-əl-ə-don；Otodus megalodon，意为“巨齿”，是一种已灭绝的鲭科鲨鱼，生活在大约230万年前至360万年前（Mya），从始新世早期至上新世的时期。它曾被认为属于 Lamnidae 家族，与大白鲨（Carcharodon carcharias）关系密切。然而，现在它被归入已灭绝的 Otodontidae 家族，该家族在早白垩纪就已与大白鲨分道扬镳。

尽管被认为是有史以来最大、最强大的掠食者之一，巨齿鲨仅从零散的遗骸中得知，其外观和最大体型仍不确定。科学家对它更接近大白鲨的矮胖版本、鲸鲨（Rhincodon typus）、浮鲨（Cetorhinus maximus）或沙虎鲨（Carcharias taurus）的看法各不相同。最新且误差范围最小的估算显示，其最大身长可达约20.3米（67英尺），体重可达约103吨（114短吨）。

Authentic Carcharocles megalodon tooth from Indonesia, Java , Cikalong 

Quality Megalodon Tooth, with good  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)
