COPE, J. C. W. 2005. Octocorallian and hydroid fossils from the Lower Ordovician of Wales. Palaeontology, 48, 2, 433–445.
John C. W. Cope Octocorallian and hydroid fossils are described from the Lower Ordovician (Arenig Series) of Wales. They include gorgoniids that are the earliest known fossils of this group: Petilavenula varifurcata gen. et sp. nov. and P. surculosa gen. et sp. nov. Pennalina crossi gen. et sp. nov. is probably also a gorgoniid but may be a hydroid. A new hydroid, Pontifennia gracilis gen. et sp. nov., is also described. Wiley Online Library
