- Abstract
A diverse fauna of three-dimensionally preserved sponges is described from nearshore volcanogenic sandstones near Llandrindod, Mid-Wales. The fauna was preserved through early marginal silicification, in rare examples with silicification of soft tissue, and includes aspicular and spicular demosponges, hexactinellids, and a heteractinid. The fauna is largely endemic, with the following new species, genera and families erected:Onerosiconcha gregaliagen. et sp. nov.,Ordinisabulo quadragintaformagen. et sp. nov.,Miritubus erinaceusgen. et sp. nov.,Vadosifistula milvusgen. et sp. nov.,Polycornua trescelestusgen. et sp. nov. (Pseudolanciculidae fam. nov.),P. entropussp. nov.,Palaeocallyoides improbabilisgen. et sp. nov.,Reticulicymbalum tresgen. et sp. nov.,Triactinella rigbyigen. et sp. nov. (Triactinellidae, fam. nov.),Spissiparies minutagen. nov.,Brevicirrus arenaceusgen. et sp. nov.,Pyritonema scopulasp. nov. (Pyritonemidae, fam. nov.) andMicroastraeum tenuisgen. et sp. nov. In addition,PseudolanciculaWebby and Trotter is recorded outside Australia for the first time, although only as isolated spicules. The environment represented by this fauna has not previously yielded articulated sponges, and thus the apparent endemism may be misleading.
