来自印度尼西亚爪哇，Cikalong 的真品巨齿鲨牙齿

高质量的巨齿鲨牙齿，尖端、齿尖和牙釉质都良好，

巨齿鲨（Carcharocles megalodon，Otodus megalodon）意为“巨齿”，是已灭绝的鲭鲨科鲨鱼物种，生活在大约2,300万至360万年前（从早中新世到上新世时期）。曾被认为属于Lamnidae科，并且是大白鲨（Carcharodon carcharias）的近亲。如今被归入已灭绝的 Otodontidae 科，该科在早白垩世就与大白鲨分道扬镳。

尽管被认为是有史以来最大、最强大的掠食者之一，巨齿鲨仅以零散化石为人所知，其外观和最大体型尚不确定。科学家们对它更可能接近大白鲨的矮胖型、鲸鲨（Rhincodon typus）、浮鲨（Cetorhinus maximus）或沙虎鲨（Carcharias taurus）之间的哪一种存在分歧。最近的估计在误差范围最小的情况下，给出最大体长约20.3米（67英尺），体重约103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)
