Abstract: A unique ammonoid assemblage from the Upper Visean-Serpukhovian Dombar Limestone comes from a meridional stretch of crinoid limestone alternating with mudstones and wackestones overfilled with ammonoid shells and crinoids but with few brachiopods, gastropods, or corals. Most ammonoids recovered from the Dombar Limestone had a shell suggesting limited swimming ability. Sedimentation in this basin was likely to have occurred in quiet setttings with good circulation beneath a fair-weather wave base and in proximity to oceanic currents.
