来源于印度尼西亚，爪哇，Cikalong 的正宗巨齿鲨牙

优质巨齿鲨牙，尖端完好，锯齿清晰，珐琅质良好，

巨齿鲨（Carcharocles megalodon，/ˈmɛɡələdɒn/ MEG-əl-ə-don；Otodus megalodon），意思是“巨大牙齿”，是一种已灭绝的鲭鲨科鲨鱼，生活在大约2300万至360万年前（Mya），从早中新世到上新世时期。它曾被认为属于鲭鲨科 Lamnidae，与大白鲨（Carcharodon carcharias）关系密切。然而，现今被归入已灭绝的 Otodontidae 科，该科在早白垩纪与大白鲨分道扬镳。

尽管被公认为有史以来最大的、最强大的捕食者之一，巨齿鲨仅以零散遗骸为人所知，其外形和最大体型尚不确定。科学家对于它的外形是否更接近大白鲨的矮壮版本、鲸鲨（Rhincodon typus）、浮鲨（Cetorhinus maximus）或沙虎鲨（Carcharias taurus）存在分歧。最近的估计在误差范围最小的前提下，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 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)
