来自印度尼西亚爪哇，Cikalong 的正宗巨齿鲨牙

高质量的巨齿鲨牙，尖端完好，牙釉质完好，

巨齿鲨（Megalodon /ˈmɛɡələdɒn/ MEG-əl-ə-don；Otodus megalodon），意为“巨大之牙”，是已灭绝的鲭形鲨科鲨鱼，生活在大约2300万到360万年前（始新世至上新世期间）。曾被认为属于速鲨科，与大白鲨（Carcharodon carcharias）关系密切；但现 now 分类于已灭绝的 Otodontidae 科，该科在早白垩纪时与大白鲨分化。

尽管被认为是有史以来最大、最强大的掠食者之一，巨齿鲨仅以碎片化遗骸为知，其外观和最大体型尚不确定。科学家们对于它更像大白鲨的健壮版本、鲸鲨（Rhincodon typus）、抚鲸鲨（Cetorhinus maximus）还是沙虎鲨（Carcharias taurus）之间存在分歧。最近的、误差范围最小的估算显示其最大长度可达约20.3米（67英尺），体重可达103吨（114短吨）。

长度：13.8厘米

Authentic Carcharocles megalodon tooth from Indonesia, Java , Cikalong 

Quality Megalodon Tooth, with good tip,  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)
