   • 1940 January, Erwin C. Stumm, “Upper Devonian Rugose Corals of the Nevada Limestone”, in Journal of Paleontology, volume 14, number 1, page 64, column 1:

     The unusually long minor septa and the restricted tabularia are features that I have not seen in any other species of Prismatophyllum.

     Tabulae are transverse plates which may be flat, convex or concave. They usually occupy a central space or tabularium, and if there is an axial complex they join with it. […] Dissepiments, the small plates usually found towards the edge of the corallum, lie peripheral to the tabularium and like the tabulae are constructed of fibro-normal tissue.

     If further investigation shows that clinotabulae are absent from the Geyerophyllidae and biform tabularia are developed, then the Geyerophyllidae should be placed in synonymy with the Petalaxidae.
