1.9" 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 11–5 million years ago. Growing up to 4 meters (13 feet) long, this sleek, fast-swimming predator had a streamlined body, pointed snout, and sharp teeth built for speed and precision hunting. Fossil evidence of Hastalis has been uncovered across the United States, Europe, and South America, highlighting its wide distribution. As a dominant predator of the open ocean, it fed on fish, squid, and even small marine mammals, playing a crucial role in shaping ancient marine ecosystems.

The teeth of Hastalis closely resemble those of modern-day mako sharks, but they are noticeably larger and more robust, reflecting its power as a predator. While the species was once classified within the Isurus genus, further research has led to its reclassification into a distinct genus due to its unique anatomical features. Overall, Hastalis holds great importance in paleontology, offering valuable insights into the evolution and diversity of ancient sharks as well as the ecological dynamics between predators and prey in prehistoric marine ecosystems.
