来自印度尼西亚爪哇，Cikalong 的真品 Carcharocles megalodon 牙齿

高质量的巨齿鲨牙，尖端、锯齿和牙釉质都很好

Megalodon (/ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon)，意为“巨齿”，是一种已灭绝的鲭形鲨鱼，生活在大约2300万年前到360万年前的中新世早期至上新世末期。曾被认为属于鲭科并与大白鲨（Carcharodon carcharias）关系密切；但现在被归入已经灭绝的 Otodontidae 家族，该家族在早白垩纪时就与大白鲨分道扬镳。

尽管被视为有史以来最大、最强大的掠食者之一，巨齿鲨的化石证据仅存于碎片，其外形和最大体长尚不确定。科学家对它更像大白鲨的矮壮版本、鲸鲨（Rhincodon typus）、抬鳃鲨（Cetorhinus maximus）还是沙虎鲨（Carcharias taurus）存在分歧。最新、误差范围最小的估计表明其最大体长可达约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)
