The Araucariaceae: An evolutionary perspective
- R. Stockey
- 1 July 1982
Abstract The Araucariaceae, containing two extant genera, Agathis and Araucaria , is a Southern Hemisphere conifer family with a very resticted present day distribution. Although the group has only a… Expand
Mesozoic Araucariaceae: Morphology and systematic relationships
- R. Stockey
- Journal of Plant Research
- 1 December 1994
The Southern Hemisphere conifer family Araucariaceae has a very restricted present day distribution, but was more widespread in the past. The genusAraucaria is represented by good fossil material in… Expand
The fossil monocot Limnobiophyllum scutatum: resolving the phylogeny of Lemnaceae.
More than 200 specimens of Limnobiophyllum scutatum (Dawson) Krassilov have been recovered from lacustrine claystones in the Paleocene Paskapoo Formation near Red Deer, Alberta. The plant was a… Expand
Todea from the Lower Cretaceous of western North America: implications for the phylogeny, systematics, and evolution of modern Osmundaceae.
The first fossil evidence for the fern genus Todea has been recovered from the Lower Cretaceous of British Columbia, Canada, providing paleontological data to strengthen hypotheses regarding patterns… Expand
The role of Hydropteris pinnata gen. et sp. nov. in reconstructing the cladistics of heterosporous ferns
Insect fossils in middle Eocene deposits from British Columbia and Washington State: faunal diversity and geological range extensions
Fossil insects in the orders Coleoptera, Hymenoptera, Diptera, and Lepidoptera were examined from nine middle Eocene localities in British Columbia, Canada, and Washington State, U.S.A. Twenty-five… Expand
Is the anthophyte hypothesis alive and well? New evidence from the reproductive structures of Bennettitales.
Bennettitales is an extinct group of seed plants with reproductive structures that are similar in some respects to both Gnetales and angiosperms, but systematic relationships among the three clades… Expand
The Princeton chert: Evidence for in situ aquatic plants
Abstract The Middle Eocene Princeton chert from southern British Columbia represents one of the richest known assemblages of permineralized Tertiary plants. Affinities with modern aquatic… Expand
Structure and relationships of the Jurassic conifer seed cone Hughmillerites juddii gen. et comb. nov.: Implications for the origin and evolution of Cupressaceae
Abstract Anatomically preserved Jurassic conifer seed cones originally described as Conites juddi Seward and Bancroft are reinvestigated and assigned to Hughmillerites juddii gen. et comb. nov. using… Expand
Phylogenetic diversification of Early Cretaceous seed plants: The compound seed cone of Doylea tetrahedrasperma.
PREMISE OF THE STUDY Discovery of cupulate ovules of Doylea tetrahedrasperma within a compact, compound seed cone highlights the rich diversity of fructification morphologies, pollination biologies,… Expand
