インドネシア・ジャワ島・チカロン産の本物のCarcharocles megalodonの歯

品質の良いメガロドンの歯、鋸歯とエナメル質が良好

Megalodon（/ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon）は「大きな歯」という意味で、約230万年前から360万年前までの初新世後期から漸新世にかけて生息していた絶滅したサメの一種です。以前はLamnidae科の一員で、ホオジロザメ（Carcharodon carcharias）の近縁と考えられていました。しかし現在は絶滅したOtodontidae科に分類されており、白亜紀前期にホオジロザメと分岐したとされています。

生物学者は、メガロドンがこれまでに生きた最大級かつ最も強力な捕食者の一つとみなす一方で、断片的な化石しか知られておらず、外見や最大サイズは不確定です。最も最近の推定では、最大長さは約20.3メートル（67フィート）、体重は約103メトリックトン（114ショートトン）とされています。

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)
