正品巨齿鲨牙，来自印尼爪哇，Cikalong

高质量的巨齿鲨牙，尖端完好，齿刃和牙釉质良好，

巨齿鲨（/ˈmɛɡələdɒn/ MEG-əl-ə-don； Otodus megalodon），意思是“巨牙”，是一种已灭绝的鲭鲨科鲨鱼，生活在约230万到360万年前的始新世至中新世晚期。它曾被认为属于灯鲨科，与大白鲨（Carcharodon carcharias）关系密切。但如今被归入已灭绝的Otodontidae科，与大白鲨在早白垩纪分道扬镳。

尽管被认为是有史以来最大、最强大的掠食者之一，巨齿鲨仅知晓到碎片状的遗骸，其外形和最大体型仍不确定。科学家对其更像大白鲨的健壮版本、鲸鲨（Rhincodon typus）、抚摸鲨（Cetorhinus maximus）还是沙虎鲨（Carcharias taurus）存在分歧。最近的、误差最小的估计显示，最大身长可达约20.3米（67英尺），体重可达约103吨（114短吨）。

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)
