WA Museum Records and Supplements | Updated 1 decade ago

Abstract - Fossil gastropods collected from the Lower Ordovician Emanuel Formation and Gap Creek Formation, Canning Basin, Western Australia, comprise eight species in seven genera, including two new species. The most common gastropods of the Emanuel Formation are Peelerophon oehlerti (Bergeron), Ecculiomphalus cf. abendanoni (Frech), Pararaphistoma (Pararaphistoma) qualteriatum (Schlotheim), Pararaphistoma (Climacoraphistoma) vaginati (Koken and Perner) and Seelya emanuelensis sp. novo This gastropod fauna shows strong resemblances to those of southeastern Asia including China and to those of South America and Western Europe, ranging in age from Tremadocian to early Arenigian. Two species of Lower Ordovician gastropod, Teiichispira kobayashi Yochelson and Jones and Oriostoma? canningense sp. nov., are described from the Gap Creek Formation.
