来自印度尼西亚爪哇，Cikalong 的真实巨齿鲨牙

优质巨齿鲨牙，尖端良好，锯齿和珐琅质完好，

巨齿鲨（Carcharocles megalodon，发音 /ˈmɛɡələdɒn/ MEG-əl-ə-don；Otodus megalodon），意为“巨大牙齿”，是一种灭绝的鲭鲨科鲨鱼，生活在大约2300万年前至360万年前的中新世晚期到上新世。它曾被认为属于狼鲨科，与大白鲨（Carcharodon carcharias）关系密切。然而，现在被归类于已灭绝的 Otodontidae 科，该科在早白垩纪与大白鲨分道扬镳。

尽管被视为史上最大、最强大的掠食者之一，巨齿鲨的证据仅限于零散的遗骸，其外观和最大体长仍不确定。科学家对其更像大白鲨的偏健身躯版本、鲸鲨（Rhincodon typus）、平背鲨（Cetorhinus maximus）还是虎鲨（Carcharias taurus）等谁更接近存在分歧。最新的估计在误差范围最小的情况下显示最大长度可达约20.3米（67英尺）、体重可达约103公吨（114短吨）。

长度 14.4 cm

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)
