来自印尼，爪哇，Cikalong 的真实巨齿鲨牙齿

优质的巨齿鲨牙，齿 serrations 与牙釉质完好，

巨齿鲨（Carcharocles megalodon，/ˈmɛɡələdɒn/ MEG-əl-ə-don；Otodus megalodon），意为“大牙”，是一种已灭绝的鲭鲨类，生活在大约2300万至360万年前的始新世到中新世之间。它以前被认为属于鲭科，与大白鲨（Carcharodon carcharias）关系密切。然而现在被归入灭绝的 Otodontidae 家族，与大白鲨在早白垩世分道扬镳。

尽管被认为是有史以来最大且最强大的掠食者之一，巨齿鲨的化石仅有片段残骸，因此它的外形和最大体型仍不确定。科学家对于它更接近大白鲨的健壮体型、鲸鲨（Rhincodon typus）、巨口鲨（Cetorhinus maximus）还是沙虎鲨（Carcharias taurus）存在分歧。最新的估计在误差范围最小的情况下，最大长度可达约20.3米（67英尺），体重可达约103公吨（114短吨）。

长度13.6 cm

Authentic Carcharocles megalodon tooth from Indonesia, Java , Cikalong 

Quality Megalodon Tooth, with good  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)
