来自印度尼西亚爪哇，Cikalong 的正品巨齿鲨牙齿

高质量的巨齿鲨牙齿，尖端完好、具锯齿和牙釉质，

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2300万年至360万年前的中新世早期至上新世时期。它曾被认为属于鲭鲨科 Lamnidae，与大白鲨（Carcharodon carcharias）关系密切。然而，现在被归入已灭绝的 Otodontidae 家族，该家族在早白垩纪与大白鲨分支开来。

尽管被公认为有史以来最大、最强大的掠食者之一，巨齿鲨仅以零散的遗骸所知，其外观和最大体长尚不确定。科学家对它更接近大白鲨的粗壮版本、鲸鲨（Rhincodon typus）、抚鲨（Cetorhinus maximus）或沙虎鲨（Carcharias taurus）之间的差异存在分歧。最新的估计（误差范围最小）显示最大体长可达约 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)
