Early Middle Cambrian corals from western New South Wales

Abstract
Three forms, Cothonion sympomatum gen. et sp. nov. with a bi-radially septate operculum, and the new species lissa and daseia of the genus Lipopora gen. nov., are described from the early Middle Cambrian Coonigan Formation in the Mootwingee district of western New South Wales, Australia. They may be representatives of hitherto unknown groups of organisms, but they are tentatively interpreted as coelenterates that reached a level of development comparable with the Anthozoa. Cothonion is placed in the new family Cothoniidae and questionably referred to the Rugosa. Lipopora is considered to be similar to Coelenteratella Korde; both are grouped in the new family Lipoporidae and tentatively referred to the Tabulata.
