化石拍卖（史前巨人）

来自印尼，爪哇，Cikalong 的正品巨齿鲨牙

高质量的巨齿鲨牙，尖端完好，齿锯齿和牙釉质完好，

巨齿鲨（/ˈmɛɡələdɒn/ MEG-əl-ə-don； Otodus megalodon），意为“巨牙”，是一种已灭绝的鲭鱼型鲨鱼，生活在大约230万至360万年前（Miocene早中新世至Pliocene时期）。它曾被认为属于鲭科，与大白鲨（Carcharodon carcharias）有密切关系。然而，如今被归入已灭绝的Otodontidae科，该科在早白垩纪就已与大白鲨分化。

尽管被视为史上最大且最强大的掠食者之一，巨齿鲨仅知之于零散遗骸，其外形和最大体型仍不确定。科学家对其更像大白鲨的粗壮版本、鲸鲨（Rhincodon typus）、大须鲨（Cetorhinus maximus）还是沙虎鲨（Carcharias taurus）存在分歧。最新的、误差范围最小的估算显示，最大身长可达约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)
