来自印尼爪哇，Cikalong 的真实大白鲨巨齿鲨（Megalodon）牙齿
高质量巨齿鲨牙，尖端、锯齿和牙釉质完好

巨齿鲨（/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，生活在大约230万年前至360万年前的始新世至上新世。曾被认为属于狼鲨科，与大白鲨（Carcharodon carcharias）是近亲。然而，现在被归入已灭绝的 Otodontidae 家族，与大白鲨在早白垩纪就分支出。 

尽管被认为是有史以来最大、最强大的掠食者之一，巨齿鲨的化石证据仅零散碎片，其外形和最大的体型仍不确定。科学家对于它更接近于大白鲨的短胖版本、鲸鲨（Rhincodon typus）、抚鲨（Cetorhinus maximus）还是沙锖鲨（Carcharias taurus）存在分歧。最近的估计给出的误差范围最小，最大身长可达约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)
