高质量的巨齿鲨牙，齿纹、尖端和牙釉质完好，

Megalodon（/ˈmɛɡələdɒn/ MEG-əl-ə-don，意为“Big tooth”）是一种已灭绝的鲭鲨类，生活在大约2300万年至360万年前，始新世早期至中新世末。曾被认为属于鲭科并且是大白鲨（Carcharodon carcharias）的近亲。然而，现在被归入已灭绝的Otodontidae科，该科在早白垩纪就已从大白鲨分化出来。

虽然被视为有史以来最大的、最强劲的掠食者之一，巨齿鲨仅以碎片化的遗骸为人所知，其外形和最大体长仍不确定。科学家对于它更像大白鲨的粗壮版、鲸鲨（Rhincodon typus）、巨口鲨（Cetorhinus maximus）还是沙虎鲨（Carcharias taurus）等谁更接近，意见不一。最新的、误差范围最小的估计显示，最大体长可达约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  serrations, tip , 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)
