description Acidaspis Overview

Acidaspis is a genus of extinct trilobites associated with the family Odontopleuridae, a group noted for elaborate defensive spines. Its members were relatively small marine arthropods with spines around the cephalon and along the pleural segments of the thorax. Fossils assigned to the genus occur in Paleozoic marine rocks and are studied by paleontologists and collectors interested in trilobite morphology, classification, and evolution.

help Acidaspis FAQ

What geological period did the Acidaspis trilobite live in?

Acidaspis is an extinct genus of trilobites that lived predominantly during the Silurian and Devonian periods. As a member of the Odontopleuridae family, these marine arthropods are famous among fossil collectors for their intricate, spiny exoskeletons.

How big did Acidaspis trilobites get?

Members of the Acidaspis genus were relatively small marine arthropods, typically reaching only a few centimeters in length. Despite their small size, they featured prominent defensive spines around their head (cephalon) and along their thoracic segments.

What makes Acidaspis fossils unique compared to other trilobite species?

Acidaspis belongs to the Odontopleuridae family, which is noted for having incredibly elaborate defensive spines covering their bodies. Paleontologists and fossil enthusiasts easily distinguish them by the dense, prickly spines extending from their cephalon and pleural segments.

Where are Acidaspis trilobite fossils commonly found today?

Fossils of Acidaspis have been discovered in various marine sedimentary deposits around the world, including notable paleontological sites in Europe and North America. They are frequently uncovered in ancient limestone and shale formations where prehistoric sea environments were preserved.
