description Cheirurus Overview

Cheirurus is an extinct genus of trilobite belonging to the family Cheiruridae, with a fossil record spanning the Ordovician through the Devonian periods. These marine arthropods are characterized by their distinctive, multi-lobed pygidium, or tail shield, which extends into prominent spines. Fossils of Cheirurus have been discovered across the globe, with significant specimens found in Europe, North America, and Asia. They are frequently studied by paleontologists to understand the diversity and evolutionary adaptations of spiny trilobites.
