来自印尼爪哇，Cikalong 的正品巨齿鲨牙齿

高质量巨齿鲨牙齿，尖端、锯齿和牙釉质完好，

巨齿鲨（Carcharocles megalodon，/ˈmɛɡələdɒn/ MEG-əl-ə-don；Otodus megalodon），意为“巨大之牙”，是一种已灭绝的鲭鲨科鲨鱼，生活在约2300万年前至360万年前的新近始新世至上新世时期。它曾被认为属于长鳍真鲨科 Lamnidae，与大白鲨（Carcharodon carcharias）有亲缘关系。然而，现在将其归类于已灭绝的Otodontidae科，该科在早白垩纪就与大白鲨分道扬镳。

尽管被认为是有史以来最大的、最强大的掠食者之一，巨齿鲨仅以零散的遗骸为人所知，其外观与最大体型尚不确定。科学家对于它更像体格较为粗壮的大白鲨的版本、鲸鲨（Rhincodon typus）、抹虎鲨？（沙虎鲨，Carcharias taurus）等谁更接近意见不一。最新、误差范围最小的估计表明，其最大身长可达约20.3米（67英尺），体重可达103公吨（114短吨）。

长度 13,0 cm

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)
