HAHN, G., BRAUCKMANN, C. 1973. Lower Viséan trilobites from Feltrim, Ireland. Palaeontology, 16, 2, 391–397.
Gerhard Hahn and Carsten Brauckmann Archegonus (Weania) feltrimensis sp. nov. is described from the Lower Visean of Feltrim, Co. Dublin, Ireland. This species combines characteristics of A. (Weania) with those of A. (Waribole) and A. (Angustibole) and shows that A. (Weania) evolved from the A. ( Waribole) stock and not from Cyrtosymbole (Pseudowaribole) as supposed by Osmolska.
