Abstract

Small silicified anthaspidellid sponges identified as Gallatinospongia conicaOkulitch and Bell, 1955 are described for the first time from the Upper Cambrian of the Great Basin where the sponges are found in situ within dendrolitic microbial reefs. This association forms the oldest anthaspidellid-microbial reefs of Laurentia.
