NUDDS, J. R. 1999. A new Carboniferous rugose coral genus from northern England. Palaeontology, 42, 2, 223–229.
John R. Nudds Pleionastraea gen. nov. of the family Lithostrotionidae is described from the Lower Carboniferous Brigantian Stage of northern England. Two species, P. magnaP. matura, are referred to it. This astraeoid/thamnasterioid genus is distinguished from Orionastraea by its larger dimensions, but is considered to have followed the same evolutionary trend of a gradual breakdown of the corallite wall.
