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

Hastalis Mako (Isurus hastalis) was a powerful species of mako shark that thrived during the Miocene epoch, around 11 to 5 million years ago. Growing up to 4 meters (13 feet) in length, this fast and streamlined predator had a sleek body, pointed snout, and sharp, efficient teeth that made it highly adapted for hunting in the open ocean. Fossil evidence of Hastalis has been uncovered across the globe, including in the United States, Europe, and South America, highlighting its widespread distribution. It likely dominated its environment, preying on fish, squid, and even small marine mammals.

The teeth of Hastalis are particularly significant—similar in shape to modern mako sharks but larger and more robust, signaling its powerful bite. Originally classified within the Isurus genus, paleontologists have since reclassified it into a distinct genus due to its unique features. This shark provides key insights into the evolutionary history of lamnid sharks and helps scientists better understand the diversity of ancient marine predators and the delicate balance of Miocene ecosystems.
