优质的巨齿鲨牙齿，尖端完好、锯齿清晰、牙釉质完好

Megalodon (/ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon)，意为“巨牙”，是已灭绝的鲭鲨科巨鲨，生活在大约230万到360万年前（中新世早期到上新世），从早中新世到古近纪。它曾被认为是 Lamp­nidae 家族的成员，与大白鲨（Carcharodon carcharias）关系密切。但现在被归入已灭绝的 Otodontidae 家族，与大白鲨在早白垩纪期间分化。

尽管被认为是史上 largest and most powerful 的掠食者之一，巨齿鲨的证据仅以碎片化遗骸存在，其外形和最大体型尚不确定。科学家对其外形可能更接近大白鲨的健壮型、鲸鲨（Rhincodon typus）、抚摸鳐鲨（Cetorhinus maximus）或砂虎鲨（Carcharias taurus）等的看法不一。最近的估算给出的最大长度在约20.3米（67英尺），体重可达约103公吨（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)
