Anatomically Preserved Staminate Inflorescences of Gynoplatananthus oysterbayensis gen. et sp. nov. (Platanaceae) and Associated Pistillate Fructifications from the Eocene of Vancouver Island, British ColumbiaDownload
Anatomically preserved specimens of globose staminate and pistillate inflorescences belonging to Platanaceae have been found in concretions at the Eocene Appian Way fossil locality on Vancouver Island, British Columbia, Canada. The structure of inflorescences and individual flowers, vascular...
Vegetative Growth of Decodon allenbyensis (Lythraceae) from the Middle Eocene Princeton Chert with Anatomical Comparisons to Decodon verticillatus.Download
Large numbers of roots and stems of aquatic Lythraceae have been found in association with fruits and seeds of Decodon allenbyensis Cevallos-Ferriz et Stockey in the Princeton chert, British Columbia, Canada. The permineralized fossils come from layer 43 in the chert, part of the Middle Eocene,...
A new species of extinct conifer plants, Emporia royalii sp. nov. Hernandez-Castillo, Stockey, Mapes et Rothwell (Emporiaceae: Voltziales), is described from the rich fossil biota of the Late Pennsylvanian, Hamilton Quarry, Kansas. This conifer has lateral plagiotropic branches with simple and...
Trawetsia princetonensis gen. et sp. nov. (Blechnaceae): a permineralized fern from the Middle Eocene Princeton ChertDownload
Trawetsia princetonensis Smith, Stockey, Nishida & Rothwell gen. et sp. nov. is described from several permineralized rhizomes, stipes, and higher-order frond members of a blechnoid fern that have been identified from the Middle Eocene Princeton Chert of British Columbia. Rhizomes bear stipes...
Cuticle micromorphology of three collections of the parasitic conifer Parasitaxus ustus (Vieillard) de Laubenfels (Podocarpaceae) was studied with scanning electron microscopy. External and internal cuticle features of abaxial and adaxial leaf surfaces of both vegetative and epimatium-bearing...
Studies of Paleozoic Seed Ferns: Anatomy and Morphology of Morphology of Microspermopteris aphyllum.Download
The discovery of numerous specimens of the monostelic pteridosperm genus Microspermop- teris in Pennsylvanian coal ball petrifactions from the Lewis Creek and What Cheer localities provides additional information about the anatomical and morphological variability within the genus. Specimens are...
Cuticle micromorphology of leaves from all five species of the Southern Hemisphere conifer genus Falcatifolium de Laubenfels (Podocarpaceaew) as studied with scanninge lectron microscopy. Both herbarium and preserved specimens were examined and showed no differences in micromorphology. External...
The Aquatic Angiosperm Trapago angulata from the Upper Cretaceous (Maastrichtian) St. Mary River Formation of Southern Alberta.Download
A floating aquatic dicot with leaves assignable to Trapago angulata has been characterized from Upper Cretaceous (Maastrichtian) deposits of the St. Mary River Formation in southern Alberta, Canada. Reconstruction of the plant is based on nearly 500 specimens of various isolated and attached...
Todea from the Lower Cretaceous of western North America: implications for the phylogeny, systematics, and evolution of modern OsmundaceaeDownload
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 of evolution and phylogeny within Osmundaceae. The fossil consists of a branching rhizome,...
