Subfossil bryophytes in eastern Beringia: their paleoenvironmental and phytogeographical significance
Download1981
Doctoral thesis. Bryophytes, more particularly mosses, are used in the paleoenvironmental reconstruction and historical biogeography of eastern Beringia, an area including Alaska and the Yukon. The Old Crow Basin in northern Yukon was studied in detail. // Appendix 2: Subfossil bryophytes...

Growth Architecture of Thucydia mahoningensis, a Model for Primitive Walchian Conifer Plants.
Download2003
Stockey, R.A., Mapes, G., Hernandez‐Castillo, G.R., Rothwell, G.W.
A large number of vegetative and fertile branching systems of Thucydia mahoningensis provide data for interpreting the growth architecture and life-history pattern of a primitive Paleozoic conifer. Internal anatomy is similar to modern conifers, indicating an arborescent life-history pattern....

Molecular phylogeny, historical biogeography, and divergence time estimates for swallowtail butterflies of the genus Papilio (Lepidoptera: Papilionidae)
Download2004
Sperling, F.A.H., Zakharov, E.V., Caterino, M.S.
Swallowtail butterflies are recognized as model organisms in ecology, evolutionary biology, genetics, and conservation biology but present numerous unresolved phylogenetic problems. We inferred phylogenetic relationships for 51 of about 205 species of the genus Papilio (sensu lato) from...

Stramineopteris aureopilosus gen. et sp. nov.: Reevaluating the Role of Vegetative Anatomy in the Resolution of Leptosporangiate Fern Phylogeny.
Download2006
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...
