来自印尼爪哇，Cikalong 的正品巨齿鲨牙齿

品质优良的巨齿鲨牙齿，尖端、锯齿和牙釉质完好，

巨齿鲨（Carcharocles megalodon）/ˈmɛɡələdɒn/ MEG-əl-ə-don； Otodus megalodon，意为“巨大牙齿”，是一种已灭绝的鲭鲨科鲨鱼，约在2300万至360万年前的中新世早期至上新世晚期生活。它曾被认为属于Lamnidae科，与大白鲨（Carcharodon carcharias）有密切关系。然而现在被归入已灭绝的Otodontidae科，该科在早白垩纪便与大白鲨分化。

尽管被认为是有史以来最大、最强大的一类掠食者之一，巨齿鲨仅知于零散的遗骸，其外形和最大体型仍不确定。科学家对于它更接近大白鲨的健壮版、鲸鲨（Rhincodon typus）、抬背鲨（Cetorhinus maximus）还是沙虎鲨（Carcharias taurus）各有意见。最近的估计在误差范围最小的情况下，最大长度约为20.3米（67英尺），体重可达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)
