A genuine fossil lower tooth from the ancient Hexanchus griseus, a deep-water shark lineage that has survived for millions of years with remarkably little evolutionary change. Often referred to as a "living fossil," the modern bluntnose six gill shark closely resembles its prehistoric ancestors.
Unlike the pointed upper teeth, the lower teeth are broad, comb-like, and lined with multiple serrated cusps. These specialized teeth worked like a saw, allowing the shark to slice through fish, marine mammals, and carrion with remarkable efficiency. This distinctive tooth design makes six gill shark fossils easily recognizable and highly desirable among collectors.
Six gill sharks have inhabited Earth's oceans for well over 100 million years, making them one of the oldest surviving shark lineages. Fossil teeth such as this offer a fascinating glimpse into ancient marine ecosystems and the incredible evolutionary success of these deep-sea predators.
A unique addition to any fossil collection, a Six Gill Bluntnose Cow Shark tooth is an excellent specimen for shark enthusiasts, fossil collectors, and anyone fascinated by prehistoric marine life.
