A new species of Protophyllocladoxylon from the Upper Cretaceous (Cenomanian-Turonian) portion of the Winton Formation, central-western Queensland, Australia

Abstract

Leaf floras in fluvial-lacustrine sediments of the Upper Cretaceous (Cenomanian-Turonian) portion of the Winton Formation suggest a community with co-dominance of angiosperms, conifers, ginkgo and other seed plants. To date wood floras associated with the Winton Formation have not been examined in detail. Winton Formation wood has been presumed to comprise araucarian, podocarp and taxodiaceous components, but this has been based largely on the identification of other plant macro and microfossils. Here we describe a new species of podocarp fossil wood from the genus Protophyllocladoxylon based on eleven specimens of silicified wood found as surface material at two broadly coeval sites in the ..
