    Abstract

    The lingulate brachiopods from the type section of the Emanuel Fonnation, Canning Basin, Western Australia are described. The fauna consists on new obolid taxa, Libecoviella divaricata n. sp., Wahwahlingula? emanuelensis n. sp., and Zhanatellidae n. gen? A, and two acrotretoids, Semitreta lauriei n. sp., and Ottenbyella shidertensis (Popov & Holmer, 1994). Contemporaneous trilobite and conodont faunas indicate a late Lancefieldian (La3) to mid Bendigonian (Be2) (=earliest Arenigian) age for the Emanuel Fonnation. The lingulate fauna is largely endemic at the species level, with minor faunal links to Kazakhstan and Bohemia.
