A new voltzialean conifer, Emporia royalii sp nov. (Emporiaceae), from the Hamilton Quarry, Kansas.
Download2009
Stockey, R.A., Rothwell, G.W., Hernandez-Castillo, G.R., Mapes, G.
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...

Analyzing taphonomic deformation of ankylosaur skulls using retrodeformation and finite element analysis
Download2012
Taphonomic deformation can make the interpretation of vertebrate fossil morphology difficult. The effects of taphonomic deformation are investigated in two ankylosaurid dinosaur taxa, Euoplocephalus tutus (to investigate effects on our understanding of intraspecific variation) and Minotaurasaurus...

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...

Beardia vancouverensis gen. et sp. nov. (Juglandaceae): Permineralized fruits from the Eocene of British Columbia
Download2006
Mindell, R.A., Stockey, R.A., Elliott, L.L.
Large numbers of permineralized juglandaceous fruits were identified in calcareous nodules from the Eocene Appian Way locality on Vancouver Island, British Columbia, Canada. The fruits, small dorsiventrally flattened nutlets, 4.5–7.0 mm long and 5.5–9.0 3 3–5 mm in diameter, were studied using...

Combining Characters of Pteridaceae and Tree Ferns: Pterisorus Radiata gen. et sp. nov., A Permineralized Lower Cretaceous Filicalean with Radial Sori
Download2006
Stockey, R. A, Rothwell, G. W.
An anatomically preserved leptosporangiate filicalean that combines characters of the Pteridaceae and tree ferns has been discovered in the Lower Cretaceous (Valanginian-Hauterivian boundary) Apple Bay flora on Vancouver Island, Canada. Exindusiate sori are radial, with numerous annulate...

Cyanogenic glycosides are secondary plant compounds that are widespread in the plant kingdom. Their biosynthesis starts with the conversion of aromatic or aliphatic amino acids into their respective aldoximes, catalysed by N-hydroxylating cytochrome P450 monooxygenases (CYP) of the CYP79 family....

H., Docking, Roderick T., Palmquist, Diana L., Nguyen, Anh, Zhao, Yongjun, Birol, Inanc, Pandoh, Pawan, Li, Maria, Taylor, Greg A., Liao, Nancy Y., Moore, Richard, Bohlmann, Joerg, Janes, Jasmine K., Jackman, Shaun D., Yuen, Macaire M. S., Huber, Dezene P. W., Jones, Steven J. M., Keeling, Christopher I.
Background The mountain pine beetle, Dendroctonus ponderosae Hopkins, is the most serious insect pest of western North American pine forests. A recent outbreak destroyed more than 15 million hectares of pine forests, with major environmental effects on forest health, and economic effects on the...

Evidence for sympodial vascular architecture in a filicalean fern rhizome: Dickwhitea allenbyensis gen. et sp. nov. (Athyriaceae).
Download2006
Rothwell, G.W., Stockey, R.A., Nishida, H., Karafit, S.J.
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...

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....
