Postcranial rhizodontid remains from Middle Paddock (central Queensland, mid-Viséan) show closest affinity to those of Strepsodus, known from the Carboniferous of Britain and eastern Canada, latest Devonian of Turkey and Upper Devonian of Colombia and Iran. The Queensland Strepsodus marks the appearance of the Rhizodontidae (a derived taxon within the Rhizodontida including Strepsodus, Rhizodus and Screbodinus) in East Gondwana; tetrapod, xenacanth and lungfish taxa from Middle Paddock also include groups not previously described from East Gondwana. This is a contribution to IGCP 421.
