Trilobites at the Devonian-Carboniferous boundary

Abstract

The drastic change within the trilobite succession close to the Devonian-Carboniferous boundary coincides with the Hangenberg Shale time equivalent which lies only a few hundred thousand years below the newly defined, conodont-based Devonian-Carboniferous boundary. The Phacopida became completely extinct, and of the Proetida only very few Brachymetopidae and Proetacea survived and gave rise to a new, final radiation of trilobites during the Permocarboniferous.
