品质：巨齿鲨牙，尖端良好，齿锯齿和牙釉质完好，

Megalodon (/ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon)，意为“大牙”，是已灭绝的鲭鲨科鲨鱼，生活在大约230万到360万年前（更新世早期至上新世），从早始中新世至上中新世。此前被认为属于LAMNIDAE家族，与大白鲨(Carcharodon carcharias)关系密切。但现在被归类于已灭绝的Otodontidae家族，该家族在早白垩世就已与大白鲨分道扬镳。

尽管被认为是有史以来最大且最强大的掠食者之一，巨齿鲨只是留存有零星化石，外形和最大体长仍不确定。科学家对它更像大白鲨的矮胖版本、鲸鲨(Rhincodon typus)、抹喉鲨(Cetorhinus maximus)还是沙鲨(Carcharias taurus)等，各有不同意见。最新的估计（误差范围最小）显示最大体长可达约20.3米（67英尺），体重可达约103公吨（114短吨）

长度：12.9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)
