Hi Jackie,
Yes, we do find Araucaria cones. Permineralized pine cones are not unusual in some areas as well. Additionally we find the winged seeds of many other conifer species (spruce, fir…) in shale deposits. We also have examples of stoboli (general word for cone) and/or seeds seeds of Ginkgo, cycads, and members of the Gnetophyta which today includes Gnetum, Ephedra and Welwitschia. Magnolia is actually a flowering plant but we do find Magnolia seeds. They have characteristic grooves which let us identify them down to the species level.
