Henderson, R. A. and Kennedy, W. J. and McNamara, K. J. (1992) Maastrichtian heteromorph ammonites from the carnarvon basin, western-australia. Alcheringa, 16 (1-2). pp. 133-170. ISSN 0311-5518 DOI 10.1080/03115519208619037Full text not available from this repository.
A comprehensive taxonomic revision of heteromorph ammonites from the Miria Formation and the uppermost horizon, a nodule bed, of the Korojon Calcarenite is presented, with major rationalisation of earlier nomenclature and new data on the faunal sequence. Eubaculites is present throughout the succession as three biostratigraphically discrete species and Nostoceras, represented by two species, is restricted to the nodule bed. Remaining elements of the heteromorph fauna are known only from the upper part of the Miria Formation, associated with a diverse assemblage of planispiral ammonites and other molluscs. Preservation of ammonites has been strongly influenced by taphonomic factors such that the biostratigraphic pattern now apparent is largely unrelated to life assemblages. Ammonites from the upper Miria Formation are of late Maastrichtian age whereas those from the nodule bed are ascribed to the early Maastrichtian.
