Lower permian colonial rugose corals, Western and Northwestern Pangaea: taxonomy and distribution

This is a comprehensive summary on the stratigraphic occurrence, geographic distribution, phylogeny, and taxonomy of Early Permian colonial rugose corals that occupied the Cordilleran-Arctic-Uralian (CAU) Realm, along the northwestern and western marine shelves and accreted terranes of the ancient supercontinent Pangaea.

It is based on all previous studies by other coral specialists, a thorough review of all published data, and on information from a very large number of new collections from new areas.
