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)

巨型大白鲨牙齿 13.0 厘米 - 牙齒化石 - Carcharocles megalodon
來自印尼、爪哇、西卡隆的正宗 Carcharocles 巨齒鯊牙齒
優質巨齒鯊牙齒,具有良好的尖端、鋸齒和琺瑯質,
大牙鲨(/ˈmɛɡələdɒn/ MEG-əl-ə-don;学名:Otodus megalodon),意为“巨大的牙齿”,是一种在大约2300万到360万年前(百万年),从早中新世到上新世时期生存的已灭绝的鲭鱼鲨鱼物种。曾被认为是鲨鱼科的一员,并与大白鲨(Carcharodon carcharias)关系密切。然而,现在被分类为已灭绝的斑鲨科(Otodontidae),该科在早白垩世时期与大白鲨分化。
雖然巨齒鯊被認為是有史以來最大、最強大的掠食者之一,但我們只能從零碎的遺骸中了解巨齒鯊,而且它的外觀和最大尺寸尚不確定。對於它是否更類似於大白鯊、鯨鯊(Rhincodontypus)、姥鯊(Cetorhinusmaximus)或沙虎鯊(Carchariastaurus)的更粗壯版本,科學家們存在分歧。誤差範圍最小的最新估計表明最大長度估計可達 20.3 公尺(67 英尺),重量可達 103 公噸(114 短噸)
长度 13.0 厘米
