Popis:	The late Miocene Mount Messenger Formation along the North Taranaki coast comprises a fining‐upwards succession of interbedded sandstones and mudstones previously interpreted as deposits of a series of submarine fans in bathyal to upper bathyal waters. The sequence was divided into three lithofacies associations: thick‐bedded basin floor fan (BFFTK); thin‐bedded basin floor fan (BFFTN); and proximal to distal channel levee complex (CLC). This study recognises a fourth unit, the thick‐bedded Ophiomorpha sandstone lithofacies association (TBOS), as another depositional environment. Ichnology is an important tool in distinguishing the lithofacies assemblages and interpreting original depositional conditions. Each of the lithofacies associations shows a distinctive relationship between lithologic parameters and ichnofauna and ichnofabric. Four ichnocoenoses are recognised, corresponding well with the four lithofacies assemblages. Ichnocoenose I, dominated by fodinichnia, coincides with BFFTK and fall...
