Stockey, Ruth A., Smith, Selena Y., Currah, Randolph S.
Two fossil poroid hymenophore fragments, one from the Cretaceous Period and the other from the Eocene Epoch, are described. The permineralized specimens were obtained from marine calcareous concretions on Vancouver Island, British Columbia, Canada, and were studied using the cellulose acetate...

Cyathea cranhamii sp. nov. (Cyatheaceae), Anatomically Preserved Tree Fern Sori from the Lower Cretaceous of Vancouver Island, British Columbia
Download2003
Stockey, Ruth A., Rothwell, Gar W., Smith, Selena Y.
Permineralized cyatheaceous sori occur among remains of conifers, fungi, and other plants in newly discovered calcareous concretions from Early Cretaceous (Barremian) marine sediments of Vancouver Island, British Columbia, Canada. Sori are superficially attached in two rows to narrow pinnules and...

Distinguishing angiophytes from the earliest angiosperms: A Lower Cretaceous (Valanginian-Hauterivian) fruit-like reproductive structure
Download2009
A remarkably diverse Lower Cretaceous (Valanginian-Hauterivian) fl ora at Apple Bay, Vancouver Island, preserves seed plants at an important time of fl oristic evolutionary transition, about the same time as the earliest fl owering plant megafossils. The fossils are permineralized in carbonate...

Vickaryous, M. K., Currie, P. J., Koppelhus, E. V., Sissons, R., Badamgarav, D.
Structure of the manus and pes has long been a source of confusion in ankylosaurs, owing to the imperfect preservation or complete lack of these parts of the skeletons in most specimens, and the fact that many species appear to have undergone a reduction in numbers of digits and phalanges. New...

Is the anthophyte hypothesis alive and well? New evidence from the reproductive structures of Bennettitales
Download2009
Stockey, R.A., Rothwell, G.W., Crepet, W.L.
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 remain controversial. This study summarizes characters of bennettitalean plants and presents new...

Morphometry of the teeth of western North American tyrannosaurids and its applicability to quantitative classification
Download2005
Samman, T., Hills, L. V., Powell, G. L., Currie, P. J.
Gross tooth morphology and serration morphology were examined to determine a quantifiable method for classifying tyrannosaurid tooth crowns from western North America From the examination of teeth in jaws, tyrannosaurid teeth could be qualitatively assigned to one of five types based on the...

Osmunda vancouverensis sp. nov. (Osmundaceae), permineralized fertile frond segments from the Lower Cretaceous of British Columbia, Canada.
Download2006
Vavrek, M.J., Stockey, R.A., Rothwell, G.W.
The Lower Cretaceous (Valanginian to Hauterivian) Apple Bay locality onVancouver Island, British Columbia, has yielded several fragments of fertile permineralized osmundaceous pinnae. Specimens are preserved in calcareous concretions, showing both internal anatomy and allowing for the...

Palaeoenvironment and palaeoecology of three Cretaceous snakes: Pachyophis, Pachyrhachis, and Dinilysia
Download2001
Caldwell, M. W., Albino, A. M.
The palaeoecology of three Late Cretaceous snakes is evaluated. Pachyophis woodwardi Nopcsa, 1923 and Pachyrhachis problematicus Haas, 1979, are Cenomanian in age and are found in carbonate rocks deposited in marine inter-reef basin environments of the European and African Tethys Sea. Dinilysia...

Two abraded, cylindrical cone specimens found in calcareous concretions from the Cretaceous Spray Formation (Late Campanian) of Vancouver Island, British Columbia, were sectioned using the cellulose acetate peel technique and characterized anatomically. Their sclerenchymatous pith is surrounded...

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...
