Paleontological evidence for the Triassic age of rocks dredged from the northern Exmouth Plateau (Tethyan foraminifers, echinoderms, and ostracodes)

Abstract

A very Late Triassic age can be proven for samples which were previously regarded as Lower Jurassic sediments. The microfossils of known stratigraphic ranges show predominant Tethyan affinities. The similiarity of the characteristic associations of "Alpine' microfaunas and facies types to those of many other sites in the western and easternmost Tethys (Papua New Guinea and Timor) demonstrates a formerly unexpected close similarity of the faunal community throughout the whole Tethys realm. -from Authors
