Strotactinus

Strotactinus is an ancient group of small sea creatures called trilobites. These trilobites lived millions of years ago and are now extinct, meaning they no longer exist today. Strotactinus belongs to a family of trilobites known as the Pliomeridae. Scientists have identified only one species within this group, named S. insularis. Studying fossils like Strotactinus helps us understand how life on Earth has changed over very long periods.
