Abstract

The Kanosh Formation of the Great Basin of western North America contains the oldest abundant and moderately diverse bryozoan fauna known from North America. Six species are here described from this formation at Ibex in the Confusion Range, Utah. They comprise three species of esthonioporine stenolaemates and three trepostomes. Two new genera (Ibexella and Kanoshopora) and three new species (I. multidiaphragmata, K. droserae, and Eridotrypa hindsi) are introduced. The endozone of Kanoshopora n. gen. is very unusual among bryozoans in being filled with vesicles that are divided by beaded walls into longitudinal files close to the boundary with the exozone.
