来自印尼爪哇，Cikalong 的真实巨齿鲨牙齿

高质量的巨齿鲨牙齿，尖端、锯齿和釉质完好，

巨齿鲨（Carcharocles megalodon，/ˈmɛɡələdɒn/ MEG-əl-ə-don；Otodus megalodon），意为“巨大牙齿”，是一种已灭绝的鲭鱼鲨科物种，生活在大约2300万年前至360万年前的始新世晚期至中新世晚期。它曾被认为属于长须鲨科，与大白鲨（Carcharodon carcharias）关系密切。然而，现今将其归入已灭绝的 Otodontidae 家族，该家族在早白垩纪从大白鲨分化出来。

尽管被公认为有史以来最大、最强大的掠食者之一，巨齿鲨仅以碎片化的遗骸为知，外形和最大体长仍不确定。科学家们在其更接近大白鲨的短躯型、鲸鲨（Rhincodon typus）、鲸鲨或沙虎鲨（Carcharias taurus）之间存在分歧。最近的估计给出的误差最小的最大长度为约20.3米（67英尺），体重约103吨（114吨短吨）。

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)
