Revision of the Carboniferous genus Aulina Smith (Coelenterata, Anthozoa)

Morphologic and stratigraphic evidence bearing on the phylogenetic relationships of aulate Carboniferous corals suggests that species previously assigned to the genus Aulina Smith represent at least six different lineages that descended from three different ancestral genera. A classification designed to better reflect phylogenetic relationships includes the new genera Aulokoninckophyllum, Aulostylus, Solenodendron, and Vesiculotubus. The new North American taxa Aulostylus tubiferus tubiferus, A. tubiferus eotubiferus, and A. bamberi are described and illustrated. Two new Chinese species, Aulina (Pseudoaulina) loi and A. (P.) sinensis, are also proposed.
