化石拍卖（史前巨人）

来自印度尼西亚爪哇，Cikalong 的正品巨齿鲨牙。

优质巨齿鲨牙，尖端、锯齿和琺珀质完好，

巨齿鲨（Megalodon，/ˈmɛɡələdɒn/ MEG-əl-ə-don； Otodus megalodon），意为“巨牙”，是一种已灭绝的鲭齿鲨，约在2300万年前至360万年前的早中新世至上新世期间生活。曾被认为属于鲭科（Lamnidae），与大白鲨（Carcharodon carcharias）关系密切。但现今被归入已灭绝的 Otodontidae 科，该科在早白垩纪便已与大白鲨分化。

虽然被认为是有史以来最大、最强大的捕食者之一，但巨齿鲨仅从零散的遗骸得知，其外观和最大体型仍不确定。科学家对它更接近哪种体型存在分歧：更像大白鲨的更结实版本、鲸鲨（Rhincodon typus）、抑或沙虎鲨（Carcharias taurus）。最新的、误差范围最小的估计表明其最大体长可达约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)
