1.8" Quality Hastalis Mako Tooth Serrated Fossil Natural Miocene Age COA

Hastalis Mako (Isurus hastalis) was a large, fast-swimming shark that lived during the Miocene epoch, approximately 11–5 million years ago. It grew up to 4 meters (13 feet) long and featured a sleek, streamlined body, a pointed snout, and sharp teeth designed for speed and precise hunting. Fossils of Hastalis have been discovered across the United States, Europe, and South America, indicating its extensive presence in ancient oceans. As a top open-ocean predator, it likely preyed on fish, squid, and marine mammals, making it one of the era's key hunters. Its teeth resemble those of modern mako sharks but are larger and more robust, underscoring its powerful bite. Originally classified under the Isurus genus, it has since been reassigned to a separate genus based on its distinct anatomical traits. Currently, Hastalis provides valuable insights into the evolution and diversity of ancient sharks and the predator-prey interactions that shaped Miocene marine ecosystems.
