WA Museum Records and Supplements | Updated 8 years ago

Abstract - Three new species of terebratulide brachiopods Cancellothlyris ascotensis sp. nov., Megerlina irenae sp. nov. and Megerlina dorothyae sp. nov. are described from the Ascot Formation, Perth Basin, Western Australia. The fauna also includes the previously described terebratulid species Anakinetica recta Richardson, 1991 and Anatida gnangarensis Richardson, 1991. The loop of A. gnangarensis is descnbed for the first time. Three further species, Austrothyris grandis (Tentson~Woods 1865), Magellania flavescens (Lamarck 1819) and an indeterminate are also described. The presence of these species In the southwest of Western Australia during the Plio-Pleistocene provides further evidence of the Importance of the Leeuwin Current to the distribution of marine invertebrates.
