Formatted abstract
Mid-Cretaceous (latest Albian–earliest Cenomanian) sediment in sevenbore cores from the Eromanga Basin (south-western Queensland) was sampled for organically preserved plant macrofossils. Among those recovered, 26 taxa of conifers have been distinguished. Families Araucariaceae, Podocarpaceae, and Cheirolepidiaceae were prominent. The Araucariaceae includeAraucaria sp., while the remainder are considered to represent extinct genera. Podocarpaceae are all species of extinct genera and two new genera are described: Eromangia andThargomindia. There are two species of Cheirolepidiaceae. One of these, Geinitzea tetragona Cantrill & Douglas, is made the type of a new genus,Otwayia, with two species, O. tetragona and O. cudgeloides, both occurring in the Eromanga Basin. No unequivocal Cupressaceae/Taxodiaceae were recognised.
