This eventually in- volved over 50 collecting localities, spread over an area from central Nevada north to southwestern Alaska (Text-fig. 1). It became immediately apparent that time and equipment were inadequate to do justice to the terebratulids and rhynchonellids, both of which re- quire elaborate preparation of many specimens to ad- equately understand the variation in expression of tax- onomically significant characters. The spiriferoids were commonly better preserved, and their usable taxonom- ic characters more readily accessible. Of these, the cyr- tinoid spiriferinaceans were a convenient group to work on, as they contain a variety of structures that are of great interest in terms of functional interpretations. Indeed, these puzzling functional interpretations are one of several important factors that have delayed pub- lication of this monograph (see Hoover, 1983; 1990). Fourteen years later, in March of 1990, having be- come increasingly aware of the many fine Late Triassic marine fossil localities that had been collected from by Canadian workers, I visited the Geological Survey of Canada in Ottawa, and surveyed its Triassic bio- stratigraphic collections. At the Canadian Survey, as in the U. S., fossils are most commonly collected by workers engaged in mapping, and chiefly interested in those forms that have biostratigraphic significance. Be- cause most biostratigraphically significant Triassic in- vertebrate macrofossils are not brachiopods, but rather ammonites or flat clams, there were few brachiopods in the collections. Indeed, the only Canadian localities represented in the GSC biostratigraphic collections that contained cyrtinoid spiriferinaceans were: (1) Nicola, British Columbia [no further information available], which yielded a sing
