来自印度尼西亚 Java，Cikalong 的正品巨齿鲨牙

高品质的巨齿鲨牙，尖端良好，锯齿和牙釉质完好，

巨齿鲨（Me g a l o d o n /ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon），意为“巨牙”，是一种灭绝的鲭鱼鲨科动物，约在新近中新世早期至上新世晚期（大约2300万至360万年前）生活。它曾被认为属于豹纹 shark 的 Lamnidae 家族，与大白鲨（Carcharodon carcharias）有亲缘关系。然而，现在被归入已灭绝的 Otodontidae 家族，该家族在早白垩纪就已从大白鲨分化出来。

尽管被认为是有史以来最大、最强的掠食者之一，巨齿鲨仅以碎片状的遗骸所知，其外观和最大体型仍不确定。科学家对它更像是大白鲨的体型更大、还是鲸鲨（Rhincodon typus）、浮鲨（Cetorhinus maximus）或沙虎鲨（Carcharias taurus）等的近似形态存在分歧。最近的估算给出的误差范围最小，最大长度估计可达约20.3米（67英尺），体重可达约103公吨（114短吨）。

长度：13.4 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)
