A sand tiger shark–dominated fauna from the Eocene Arctic greenhouse

Autor: J. Howard Hutchison, Aspen Padilla, Arthur R. Sweet, Michael D. Gottfried, Jaelyn J. Eberle

Publikováno v: Journal of Vertebrate Paleontology. 34:1307-1316

We describe a new shark fauna from Canada's westernmost Arctic island, Banks Island, Northwest Territories, based upon thousands of shark teeth recovered from lower–middle Eocene sediments of the Cyclic Member (Eureka Sound Formation) on northern B

Middle Jurassic to Lower Cretaceous paleoclimate of Sverdrup Basin, Canadian Arctic Archipelago inferred from the palynostratigraphy

Autor: Ashton F. Embry, Graeme T. Swindles, Jennifer M. Galloway, Hamed Sanei, Arthur R. Sweet, Keith Dewing, Thomas Hadlari

Publikováno v: Marine and Petroleum Geology. 44:240-255

Jurassic to Cretaceous strata of Sverdrup Basin contain both marine and nonmarine fossils that serve to date interlayered sandstone and mudstone units and interpret paleoenvironments and paleoclimates. Applying a multi-variate statistical approach to

Correlating middle Cretaceous palynological records from the Canadian High Arctic based on a section from the Sverdrup Basin and samples from the Eclipse Trough

Autor: James W. Haggart, Adam T. Pugh, Graeme T. Swindles, Ashton F. Embry, Jennifer M. Galloway, Claudia J. Schröder-Adams, Arthur R. Sweet

Publikováno v: Palynology. 36:277-302

Quantitative palynological analyses undertaken on the middle Cretaceous Hassel Formation of the Sverdrup Basin and reputedly equivalent rocks from the Eclipse Trough, about 850 km east, provide convincing evidence that they are coeval and of Late Alb

Biostratigraphically useful Late Cretaceous–Paleocene Terrestrial palynomorphs from the Canadian Western Interior Sedimentary Basin

Autor: Dennis R. Braman, Arthur R. Sweet

Publikováno v: Palynology. 36:8-35

The northern part of the North American Western Interior Sedimentary Basin has yielded well-preserved terrestrial palynomorphs whose occurrences allow the biostratigraphic characterization of the basin. Data have been compiled from sections that in c

The Cretaceous succession at Mount Tatlow, British Columbia, is a cornerstone of Cordilleran stratigraphy, preserving a mostly continuous record of upper Lower Cretaceous to lower Upper Cretaceous sedimentary strata. The succession is capped by volca

Petroleum source rock potential of Whitehorse trough: a frontier basin in south-central Yukon

Autor: Grant W. Lowey, Arthur R. Sweet, Martin G. Fowler, Darrel G.F. Long, Michael J. Orchard

Publikováno v: Bulletin of Canadian Petroleum Geology. 57:350-386

Whitehorse trough is a frontier basin in south-central Yukon that is thought to contain gas and possibly oil. It consists of up to 7000 m of sedimentary and volcanic rocks referred to as the Lewes River Group (Triassic), Laberge Group (Jurassic), and
