Evidence for sympodial vascular architecture in a filicalean fern rhizome: Dickwhitea allenbyensis gen. et sp. nov. (Athyriaceae).Download
A new genus and species of anatomically preserved fossil filicalean ferns Dickwhitea allenbyensis gen. et sp. nov. is described from the Middle Eocene Princeton Chert of southern British Columbia, Canada. Rhizomes have a parenchymatous pith surrounded by a ring of five amphiphloic cauline bundles...
Permineralized ferns from the middle Eocene Princeton chert. I. Makotopteris princetonensis gen. et sp. nov. (Athyriaceae).Download
The occurrence of numerous anatomically preserved specimens of an extinct filicalean fern in the middle Eocene Princeton chert from southern British Columbia, Canada, provides the basis for characterizing a new genus and species of the Athyriaceae. Fossils include narrow horizontal rhizomes with...
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...
Six ovulate, permineralized cones, four cone-scale complexes, and one isolated seed are described from the Upper Cretaceous Upper Yezo and Miho Groups from Hokkaido, Japan, and Saghalien, Russia. Cones are spherical, 3.5-6.0 cm in diameter, with prominent thick bracts. Thick ovuliferous scales...
