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...

Mosasaurs were a successful and diverse group of marine lizard that existed during the Cretaceous Period, spanning a period of geologic time from the Turonian to Maastrichtian. Their fossils are found around the world, although most records are known from the Northern Hemisphere. The Southern...

Preservation of Tissue Structures in Late Cretaceous Vertebrate Remains from Alberta, Canada
DownloadFall 2020
Here I investigate the rates of preserved original organic tissue and their quality within vertebrate bones that were preserved during the late Cretaceous of Alberta. Specimens recovered from the Dinosaur Park Formation provide a baseline for comparison to four other Alberta Formations (Brazeau,...

Relationships among Fossil and Living Dipteridaceae: Anatomically Preserved Hausmannia from the Lower Cretaceous of Vancouver Island.
Download2006
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...

Systematics and palaeobiology of the crested hadrosaurine Saurolophus from Canada and Mongolia
DownloadFall 2011
Reappraisal of Saurolophus confirms Saurolophus osborni and Saurolophus angustirostris as distinct species. Synapomorphies of Saurolophus include a spike-like pseudonarial crest formed by the nasals, frontals, and prefrontals; tripartite frontals with anteroventral and posterodorsal extensions...

The name, mosasaurs, generally refers to a group of extinct, highly aquatically adapted and large-bodied squamates that lived exclusively during the Late Cretaceous, approximately from 93 to 65 million years ago, in the oceans worldwide. Plioplatecarpines (Plioplatecarpinae) were medium-sized...

The Ankylosauria is a group of herbivorous, quadrupedal, armoured dinosaurs subdivided into at least two major clades, the Ankylosauridae and the Nodosauridae. The most derived members of the Ankylosauridae had a unique tail club formed from modified, tightly interlocking distal caudal vertebrae...

The development and biomechanics of theropod teeth and comparisons with other reptiles: a functional analysis
DownloadSpring 2012
Teeth are important for taxonomic studies. They are often the only remains found of certain vertebrates in the fossil record. This is because they are more resistant to weathering than most bones, they are small, and they are generally abundant. Most reptiles have homodont dentition, and the...
