来自印度尼西亚爪哇，Cikalong 的正品巨齿鲨牙齿

高质量的巨齿鲨牙齿，尖端良好，具备清晰锯齿与完整釉质，

巨齿鲨（Megalodon，发音 /ˈmɛɡələdɒn/，MEG-əl-ə-don；学名 Otodus megalodon），意为“大牙齿”，是一种已灭绝的鲭鲨科鲨鱼，生活在大约2300万至360万年前的新近中新世到上新世期间。先前常被认为属于鳐齿鲨科 Lamnidae，与大白鲨（Carcharodon carcharias）关系密切。然而，现今将其归入已灭绝的 Otodontidae 科，该科在白鲨出现早白垩纪就已分化。

尽管被认为是史上最大的、最强大的掠食者之一，巨齿鲨仅以零散的化石遗骸为人所知，其外形及最大体长仍不确定。科学家就它更可能更像大白鲨的粗壮版本、鲸鲨（Rhincodon typus）、露脊鲨（Cetorhinus maximus）或沙虎鲨（Carcharias taurus）之间存在分歧。最新的、误差范围最小的估计给出的最大体长为约20.3米（67英尺），体重可达103公吨（114短吨）

长度：10.4 cm

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)
