Megalaspides

Megalaspides is an extinct genus of fossil marine arthropods called trilobites. These ancient creatures lived during the later part of the Arenig stage of the Ordovician Period, a time long ago.

Scientists think Megalaspides lived about 478 to 471 million years ago. Like other trilobites, it was a sea creature with a hard shell. It lived in the oceans of a very different Earth. Studying fossils like Megalaspides helps us learn about life from long ago and how animals have changed over time.
