化石拍賣（史前巨無霸）

来自印度尼西亚爪哇岛，Cikalong 的真实巨齿鲨牙。
高质量的巨齿鲨牙，尖端完好、锯齿和牙釉质完好，

巨齿鲨（Megalodon /ˈmɛɡələdɒn/ MEG-əl-ə-don；Otodus megalodon），意思是“巨大的牙齿”，是一种已灭绝的鲭鲨科鲨鱼，生活在大约2300万到360万年前，早中新世至上新世时期。此前曾被认为属于Lamnidae科，与大白鲨(Carcharodon carcharias)有密切关系。然而，如今被归入灭绝的Otodontidae科，在早白垂纪与大白鲨分道扬镳。

尽管被视为有史以来最大、最强大的掠食者之一，巨齿鲨仅有碎片化化石可供研究，其外形和最大体型仍不确定。科学家对于其更像大白鲨的结实版本、鲸鲨（Rhincodon typus）、抚鲸鲨（Cetorhinus maximus）还是虎鲨（Carcharias taurus）存在分歧。最近一次误差范围最小的估计，最大长度可达约20.3米（67英尺），体重可达103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)
