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.\n\n巨齿鲨（Mełagodon 的名字来源为“巨大之牙”）是一种灭绝的鲭鲨科物种，生活在大约2300万年前至360万年前的新近始新世至古近纪晚期。它曾被错误地认为属于牙鲨科 Lamnidae，与大白鲨（Carcharodon carcharias）关系密切。但如今被归入灭绝的 Otodontidae 家族，该科在早白垩纪时期就已与大白鲨分道扬镳。\n\nWhile 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)\n\n尽管被认为是有史以来最大、最强大的掠食者之一，巨齿鲨的存在仅以碎片化化石为据，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版、鲸鲨（Rhincodon typus）、滨鲨（Cetorhinus maximus）还是沙虎鲨（Carcharias taurus）存在分歧。最新且误差范围最小的估计显示其最大长度可达约20.3米（67英尺），体重可达约103公吨（114短吨）。\n\nLenght 9,2 cm\n将通过 PostNL 投保运输。\nItem UUU39
