化石拍卖（史前巨人）

来自印度尼西亚爪哇岛Cikalong的正品巨齿鲨牙。

高品质巨齿鲨牙，尖端完好，齿锯齿和牙釉质完好。

巨齿鲨（Megalodon/ˈmɛɡələdɒn/ MEG-əl-ə-don； Otodus megalodon）意为“巨牙”，是一种已灭绝的鲭鲨科鲨鱼，生活在大约2300万年前至360万年前的新近始新世至上新世。曾被认为属于鲭鲨科，与大白鲨（Carcharodon carcharias）关系密切。然而现在被归入已灭绝的 Otodontidae 家族，该科在早白垩纪就与大白鲨分道扬镳。

尽管被认为是有史以来最大、最强大的掠食者之一，巨齿鲨仅知悉的化石残骸零散，其外形和最大体型仍不确定。科学家对它更像大白鲨的矮胖版、鲸鲨（Rhincodon typus）、抚鲸鲨（Cetorhinus maximus）还是沙虎鲨（Carcharias taurus）谁更接近存在分歧。最新在误差范围最小的估计显示，最大身长可达约20.3米（67英尺），体重可达约103吨（114短吨）。

长度11.3厘米

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)
