Abstract
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.
