来自印度尼西亚 Java（爪哇）、Cikalong 的正品巨齿鲨牙

优质巨齿鲨牙，尖端、锯齿和釉质完好，

巨齿鲨（/ˈmɛɡələdɒn/ MEG-əl-ə-don；Otodus megalodon），意为“巨牙”，是一种已灭绝的鲭鲨科鲨鱼，生活在大约2300万年前至360万年前的新生代始新世至上新世期间。从中新世早期到上新世的时期。它曾被认为属于 Lamnidae 家族，与大白鲨（Carcharodon carcharias）关系密切。然而，现在被归入已灭绝的 Otodontidae 科，与大白鲨在早白垩纪分化。

尽管被认为是有史以来最大的、最强大的掠食者之一，巨齿鲨仅从零散的化石中得知，其外观和最大体型仍不确定。科学家们对它更像大白鲨的结实版、鲸鲨（Rhincodon typus）、抚鳃鲨（Cetorhinus maximus）还是沙虎鲨（Carcharias taurus）之间存在分歧。最近一个误差范围最小的估计给出的最大身长约为20.3米（67英尺），体重约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)
