Hurum, J. H., Sabath, K., Currie, P. J.
Tyrannosauridae can be subdivided into two distinct subfamilies-the Albertosaurinae and the Tyrannosaurinae. Previously recognized subdivisions Aublysodontinae and Shanshanosaurinae are rejected because they are based on insufficient material and juvenile specimens. Our results are based upon a...

Systematics of an Oligocene-Aged Fossil Snake Assemblage from the White River Formation, Wyoming
DownloadSpring 2014
Extinct snake taxa are primarily recognized from isolated vertebrae. A new specimen from the Oligocene of Wyoming provides a rare opportunity to examine four nearly complete and articulated fossil snakes. Informally assigned previously to the ‘erycine’ vertebral form taxa Ogmophis and...

Living platynotan lizards are represented by two families: Helodermatidae, consisting of two species limited to south-western North America and north-western Central America; and Varanidae, with 54 species distributed throughout Africa, south-east Asia and Australia. Modern members of Platynota,...

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...

Rothwell, Gar W., Stockey, Ruth A., Hoffman, Georgia L.
More than 200 specimens of Limnobiophyllum scutatum (Dawson) Krassilov have been recovered from lacustrine claystones in the Paleocene Paskapoo Formation near Red Deer, Alberta. The plant was a floating, aquatic angiosperm with helically arranged, ovate leaves attached in small rosettes. Rosettes...

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...
