正品 印尼 Java 匠湖 Cikalong 的巨齿鲨牙牙。

高质量的巨齿鲨牙，尖端完好，锯齿清晰，琺瑯完好。

巨齿鲨（Megalodon；/ˈmɛɡələdɒn/ MEG-əl-ə-don； Otodus megalodon），意为“巨牙”，是一种已灭绝的鲭鱼鲨科海洋生物，生活在大约2300万至360万年前的中新世早期至上新世。曾被认为属于长须鲨科，与大白鲨（Carcharodon carcharias）关系密切；如今被归入已灭绝的 Otodontidae 家族，与大白鲨在白垩纪早期分化。

尽管被认为是有史以来最大、最强大的掠食者之一，巨齿鲨仅以碎片化化石为人所知，其外形和最大体长仍不确定。科学家对其更像大白鲨的矮胖型、鲸鲨（Rhincodon typus）、鲸鲨、还是沙虎鲨（Carcharias taurus）等存在分歧。最新的估计，误差范围最小，给出最大体长约 20.3 米（67 英尺）、体重高达 103 公吨（114 短吨）。

长度 10.4 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)
