Taxonomic list

• The tommotiid remains described below occurred in the flanks of archaeocyathan–microbial patches and bioherms in association with chancelloriid sclerites, sponge spicules, hyoliths, and tube-shaped microfossils (hyolithelids, torellellids), brachiopods and trilobites. At Tazemmourt, their occurrence is restricted to the lower 50 m of the Amouslek Formation.
