来自印度尼西亚爪哇，Cikalong 的正品巨齿鲨（Carcharocles megalodon）牙齿

优质巨齿鲨牙，尖端完好、锯齿和牙釉质良好，

Megalodon (/ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon)，字面意思是“巨牙”，是一种已灭绝的鲭型鲨鱼，生活在大约2300万年前至360万年前的新生代始中新世至上新世时期。它曾被认为属于鲭科（Lamnidae），与大白鲨（Carcharodon carcharias）关系密切。然而，现在归入已灭绝的Otodontidae科，该科在早白垩纪就已从大白鲨分化出来。

尽管被视为有史以来最大、最强大的掠食者之一，巨齿鲨仍仅知于零星的化石遗骸，其外观和最大体型尚不确定。科学家对于它更像大白鲨的粗壮版本、鲸鲨（Rhincodon typus）、滑鳃鲨（Cetorhinus maximus）还是沙虎鲨（Carcharias taurus）之间存在分歧。最新的最小误差范围估计显示，最大长度可达约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)
