description Zacanthoides Overview

Zacanthoides is an extinct genus of corynexochid trilobite that lived during the Middle Cambrian period. Fossils of this marine arthropod are primarily found in the Burgess Shale of British Columbia and other related deposits across North America. The genus is distinguished by its heavy spination, featuring prominent spines on both the cephalon (head shield) and the pygidium (tail shield). Paleontologists study these well-preserved fossils to better understand the biodiversity and morphological diversity of early Paleozoic marine ecosystems.
