来自印尼爪哇，Cikalong 的真实巨齿鲨（Carcharocles megalodon）牙齿

高质量巨齿鲨牙，牙尖完好，锯齿和牙釉质良好，

巨齿鲨（/ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon），意为“巨牙”，是一种已灭绝的鲭鱼鲨科，约生活在23至360万年前（Mya），从早中新世到上新世。它曾被认为属于鲭科并且是大白鲨（Carcharodon carcharias）的近亲。然而，现在被归入已灭绝的 Otodontidae 家族，该家族在早白垩纪便已与大白鲨分道扬镳。

虽然被认为是有史以来最大的、最强大的掠食者之一，但巨齿鲨仅以零散的化石遗骸为人所知，其外形和最大体型仍存在不确定。科学家对其更像大白鲨的哪一版本、抹香鲸鲨（Rhincodon typus）、鲸鲨（Cetorhinus maximus）还是虎鲨（Carcharias taurus）有不同看法。最近的一个估算给出的误差范围最小，最大长度推测可达约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)
