A Late Devonian microfossil with dasyclad algae affinities from northwestern Australia

Abstract

The affinities of a puzzling microfossil, Ningbingellina veeversi n. gen., n. sp., originally reported from the Late Devonian Ningbing Limestone, in the Bonapart Gulf Basin, Western Australia are discussed. Links with the thallus of uncalcified dasycladale Aciculelleae, with udoteaceans, and with calcispheres are explored, and an affinity with calcified dasycladale sporangium is tentatively proposed.
