Hernandez-Castillo, G.R., Stockey, R.A., Beard, G.
Two permineralized conifer pollen cones have been identified from the AppianWay locality on the east coast of Vancouver Island, British Columbia. These cones, found in marine calcareous nodules with invertebrates, are Eocene in age and have been studied with the cellulose acetate peel technique....

Bunya pine (Araucaria bidwillii Hooker) produces large seeds that consist of a massive megagametophyte that surrounds an embryo 25-30 mm long and 3-5 mm in diameter. The seeds germinate on the soil surface, but elongation of the cotyledonary tube pushes the hypocotyl, with its associated plumule...

Dromaeosaurids were small to medium sized theropod dinosaurs that diversified during the Late Cretaceous, reaching a near cosmopolitan distribution. They were diverse in morphology from the small four-winged gliders of Microraptorinae, to the bear-sized giant ‘raptors’ like Achillobator or...

The Evolutionary Ecology of Parasitic Strategies: Experimental Evolution with a Facultatively Ectoparasitic Mite
DownloadSpring 2019
Although parasitism is a ubiquitous lifestyle, little empirical evidence exists for how and why parasitism evolves from free-living lineages. Analysis of phylogenetic relationships among taxa that exhibit a range of lifestyles has aided in the development of a commonly proposed hypothesis for the...

The mitochondrial genome of the hexactinellid sponge Aphrocallistes vastus: Evidence for programmed translational frameshifting
Download2008
Rosengarten, R.D., Sperling, E.A., Leys, S.P., Dellaporta, S.L., Moreno, M.A.
Background: Mitochondrial genomes (mtDNA) of numerous sponges have been sequenced as part of an ongoing effort to resolve the class-level phylogeny of the Porifera, as well as to place the various lower metazoan groups on the animal-kingdom tree. Most recently, the partial mtDNA of two glass...

Three species of Cretaceous marine squamates are described or redescribed. The first, Pontosaurus ribaguster is described from a relatively complete specimen discovered on Hvar Island, Croatia. Preservation of identifiable nektonic teleosts within the gastric cavity (the first identifiable...

The Paleobiology, Paleoecology, and Evolution of Thescelosauridae (Ornithischia) from Alberta, Canada
DownloadFall 2021
Thescelosauridae is a basal neornithischian dinosaur clade that flourished in the Cretaceous from the Aptian to the Maastrichtian. This diverse but poorly studied group of small-bodied herbivores is divided taxonomically into Orodrominae and Thescelosaurinae, and existed in Asia and North and...

The probable association of feather mites of the genus Ingrassia (Analgoidea: Xolalgidae) with the blue penguin Eudyptula minor (Aves: Sphenisciformes) in Australia.
Download2008
A new feather mite species, Ingrassia eudyptula n. sp. (Xolalgidae: Ingrassiinae), is described from the blue penguin Eudyptula minor (J. B. Forster, 1781) in Australia. This is the first description of a feather mite species from representatives of the avian order Sphenisciformes, which had...
