FIRST OCCURRENCE OF AN IN SITU ANTHASPIDELLID SPONGE IN A DENDROLITE MOUND (UPPER CAMBRIAN; GREAT BASIN, USA)

Small silicified anthaspidellid sponges identified as Gallatinospongia conica Okulitch 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-m...

Description
Summary:Small silicified anthaspidellid sponges identified as Gallatinospongia conica Okulitch 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.
