化石拍賣（史前巨無霸）

来自印度尼西亚爪哇，Cikalong 的正品巨齿鲨牙 

优质巨齿鲨牙，牙尖完好，齿缘锯齿清晰，牙釉质完好，

巨齿鲨 (Otodus megalodon) /ˈmɛɡələdɒn/ MEG-əl-ə-don，意为“巨牙”，是一种已灭绝的鲭鲨科鲨鱼，生活在大约230万年前至360万年前的始中新世至上新世时期。曾经被认为属于鲭科并且是大白鲨(Carcharodon carcharias)的近亲。然而现在归入已灭绝的 Otodontidae 科，该科在早白垩纪便与大白鲨分道扬镳。

尽管被视为有史以来最大、最强的捕食者之一，巨齿鲨的化石仅有零星残骸，其外形和最大体型仍不确定。科学家对于它更像大白鲨的更健壮版本、鲸鲨( Rhincodon typus )、巨牙鲨(Cetorhinus maximus)还是沙虎鲨(Carcharias taurus)的看法不一。最近的估计在误差范围最小的情况下，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)
