来自印度尼西亚，爪哇，Cikalong 的真实巨齿鲨牙

高质量的巨齿鲨牙，尖端、锯齿和牙釉质完好

巨齿鲨（/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，生活在大约2300万年至360万年前（从始新世早期到中新世晚期）。它曾被认为属于 Lamnidae 家族，与大白鲨（Carcharodon carcharias）关系密切。然而，现已归入已灭绝的 Otodontidae 家族，该家族在早白垩纪就与大白鲨分道。

虽然被认为是有史以来最大、最强大的捕食者之一，但巨齿鲨仅以零散化石证据为人所知，其外形和最大体型尚不确定。科学家对其外形更接近哪种鲨鱼存在分歧：更像大白鲨的健壮版本、鲸鲨（Rhincodon typus）、抚鳃鲨（Cetorhinus maximus）还是沙虎鲨（Carcharias taurus）？

最近的估计在最小误差范围内，最大身长约为20.3米（67英尺），体重可达103吨（114短吨）

长度14.4厘米

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)
