Anemia quatsinoensis sp nov (Schizaeaceae), a permineralized fern from the lower Cretaceous of Vancouver Island.
Download2006
Stockey, R. A., Rothwell, G. W., Hernandez-Castillo, G. R.
Anatomically preserved schizaeaceous vegetative and fertile organs have been identified from the Apple Bay locality (Lower Cretaceous) of Vancouver Island, British Columbia. Specimens are permineralized in calcareous nodules that contain numerous plants and marine invertebrates. Fertile pinnules...

Aroid Seeds from the Middle Eocene Princeton Chert ( Keratosperma allenbyense , Araceae): Comparisons with Extant Lasioideae.
Download2003
A reinvestigation of more than 200 new specimens of Keratosperma allenbyense Cevallos-Ferriz et Stockey from the Middle Eocene Princeton chert allows a more detailed comparison with living Araceae and provides evidence for the evolution of the lasioid clade. The anacampylotropous seeds possess a...

Beard, G., Rothwell, G. W., Stockey, R. A., Mindell, R. A.
A permineralized gleicheniaceous rhizome with an attached stipe base has been identified from the Appian Way locality on Vancouver Island, British Columbia, Canada. The specimens are preserved in Middle Eocene marine calcareous concretions that are studied using the cellulose acetate peel...

Little, S. A., Rothwell, G. W., Stockey, R. A.
Anatomically preserved foliage of a dipteridaceous fern has been identified in both calcareous nodules and fine-grained, carbonate-cemented sandstone from the early Cretaceous (Hauterivian-Barremian) Apple Bay locality from Vancouver Island, British Columbia, Canada. Fronds with attached...

Reproductive biology of the Cerro Cuadrado (Jurassic) fossil conifers: Pararaucaria patagonica Wieland
Download1977
Seventy-two silicified cone specimens of Pararaucaria patagonica Wieland from the Cerro Cuadrado (Jurassic) petrified forest in Patagonia were studied by use of thin sections and reflected light. Traces from the cone axis stele to the bract and ovuliferous scale are separate at their origins. In...

Little, S. A., Stockey, R. A., Rothwell, G. W.
The discovery of two anatomically preserved rhizomes with attached stipe bases and adventitious roots contributes to our knowledge of filicalean fern diversity and evolution. Specimens are preserved in marine carbonate nodules at the Lower Cretaceous (Valanginian to Hauterivian) Apple Bay...

Lepage, B. A., Currah, R. S., Stockey, R. A.
The middle Eocene Princeton chert locality in southern British Columbia, Canada, contains one of the best-preserved permineralized Tertiary floral assemblages known in North America. The quality of pres- ervation of the vascular plant and fungal remains is exquisite because anatomical and...
