An Early Devonian orbiculoid brachiopod fauna was reported by Boucot and others (1967) from the Crashsite Quartzite of the northern Heritage Range of the Ellsworth Mountains. Re-collection on this site from strata now known as Mt. Wyatt Earp Formation of the Crashsite Group (Spörli, this volume) has yielded a diverse but sparse and poorly preserved fauna dominated by orbiculoid brachiopods (Orbiculoidea cf. falklandensis Rowell). Also present in the fauna are cephalopods (identifiable only to the order Orthocerida), pelecypods (Nuculites aff. N. cuneiformis Conrad; and Grammysiodea? sp. indt.), a rostroconch (Hippocardia? sp. indt.), gastropods (Holopea? sp. indt.),...
