来自印尼爪哇岛，Cikalong 的真实巨齿鲨牙齿

高质量的巨齿鲨牙齿，尖端良好，锯齿和牙釉质完好，

巨齿鲨（Megalodon /ˈmɛɡələdɒn/，MEG-əl-ə-don； Otodus megalodon），意为“巨牙”，是一种已灭绝的鲭科鲨鱼，约在9600万年前至360万年前的中新世早期至上新世晚期之间生活。它曾被认为属于 Lamnidae 科，与大白鲨（Carcharodon carcharias）关系密切。然而，现今将其归入已灭绝的 Otodontidae 科，该科在早白垩纪时就已与大白鲨分道。

尽管被认为是有史以来最大、最强的掠食者之一，巨齿鲨仅凭零散的遗骸被认识，其外形和最大体型仍不确定。科学家对其外形更可能接近于大白鲨的健壮版、鲸鲨（Rhincodon typus）、笛鲨（Cetorhinus maximus）或沙虎鲨（Carcharias taurus）等哪一支存在分歧。最近的估计在误差范围最小的情况下，最大身长约为20.3米（67英尺），体重可达103公吨（114短吨）。

长度 10,7 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)
