来自印度尼西亚爪哇的正宗巨齿鲨(Carcharocles megalodon)牙，Cikalong

高质量的巨齿鲨牙，尖端、锯齿和牙釉质均完好，

巨齿鲨（Carcharocles megalodon；发音 /ˈmɛɡələdɒn/， MEG-əl-ə-don），意为“巨牙”，是一种已灭绝的鲭科鲨鱼，生活于大约2300万到360万年前，始新世早期至新近纪晚期。此前人们认为它属于鲭科 Lamnidae，与大白鲨（Carcharodon carcharias）有密切亲缘关系。然而，现在它被归类于已灭绝的 Otodontidae 家族，该科在早白垩纪就与大白鲨分道扬镳。

尽管被普遍认为是有史以来最大、最强大的捕食者之一，巨齿鲨仅以零散的化石片段为人所知，其外形和最大体长仍不确定。科学家对它更可能更像大白鲨的矮壮版本、鲸鲨（Rhincodon typus）、沐浴鲨（Cetorhinus maximus）或沙虎鲨（Carcharias taurus）有分歧。最新给出、误差最小的估计显示，最大体长可达约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)
