An odontogriphid from the Upper Permian of Australia

A problematic organism, Bowengriphus perphlegis gen. et sp. nov., is descri bed based on two specimens from the Late Permian Rangal Coal Measures of ea stern central Queensland. It displays a double-looped feeding apparatus bea ring small conical elements, considered homologous with that of the suppose d lophophorate Odontogriphus omalus Conway Morris, 1976, from the Middle Ca mbrian Burgess Shale of British Columbia, Canada. Odontogriphids are thus i nterpreted as a group that survived through the Palaeozoic and made the tra nsition from marine to freshwater environments. Recent proposals that odont ogriphids are stem-group chordates are not well established.
