来自印尼，爪哇，Cikalong 的正品巨齿鲨牙

高质量巨齿鲨牙，尖端、锯齿和牙釉质完好，

巨齿鲨（Megalodon /ˈmɛɡələdɒn/ MEG-əl-ə-don；Otodus megalodon），意为“巨大牙齿”，是已灭绝的鲭鲨目鲭鱼科中的一种，生活在约2300万至360万年前的中新世早期至上新世晚期。此前曾被认为属于大白鲨科 Lamnidae，与大白鲨（Carcharodon carcharias）关系密切。然而，现在它被归入已灭绝的 Otodontidae 科，该科在早白垩纪时期与大白鲨分化。

尽管被公认为有史以来最大、最强大的掠食者之一，巨齿鲨仅以碎片化的遗骸为人所知，其外观和最大体长尚无定论。科学家对于它更像是大白鲨的矮胖版本、鲸鲨（Rhincodon typus）、抹香鲨（Cetorhinus maximus）或沙虎鲨（Carcharias taurus）等的哪一种意见不一。最新的、误差最小的估计表明，最大体长可达约20.3米（67英尺），体重可达103公吨（114短吨）。

长度 13.5 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)
