Pratt. New information on olenelline trilobites from the Cambrian Sekwi Formation in northwestern Canada Francine R. Abe, Bruce S. Lieberman, Michael C. Pope, and Kelly Dilliard. The physical stratigraphy and biostratigraphy of Lower Cambrian strata in the Mackenzie Mountains received considerable attention from the Geological Survey of Canada and various mining companies in the s and s, in part the result of their potential as hosts for Mississippi Valley type lead-zinc ore.

This paper focuses on upper lower Cambrian (provisional Cambrian Series 2) trilobites from the Beishan area, northwestern Gansu Province of China.

The trilobite fauna includes several palaeobiogeo-graphically and biostratigraphically important taxa that are valuable for constraining early Cambrian plate configurations.

Lower Cambrian. Six new genera, one new subgenus, and ten new species of trilobites are described from the Upper Cambrian Chopko Formation from a section of the Chopko River, Norilsk District, northwestern part of the Siberian Platform. These include one genus and two species of agnostids and five genera, one subgenus, and eight species of polymerids.

Here, trilobites can be found in Miner’s Hollow, Cataract Canyon, Dry Canyon, and the area between Antimony and Hanson Canyons.

Brown and grey shales that make up the Lower Cambrian Eager Formation in the vicinity of Cranbrook and Fort Steele contain numerous fragments and many complete specimens of olenellid trilobites.

These trilobites are invariably the oldest trilobites found at localities on all continents, but they are fully formed trilobites and not obviously.

A new species of olenelline trilobite, Nevadella keelensis, is described from the Early Cambrian (Cambrian Series 2, Stage 3) in the Sekwi Formation, Mackenzie Mountains, Canada. The difficulty in discerning between Nevadia Walcott, and Nevadella Raw, is discussed, and a revision of the two genera is suggested, particularly with the.

A single locality from the lower McKay Group on a small tributary of Tanglefoot Creek in the Kootenay Ranges, about km east north east of Fort Steele in southeastern British Columbia has yielded an astonishingly abundant and rich Upper Cambrian trilobite fauna of latest Steptoean age (click on satellite image to download the file of the locality).

The Cambrian System is well represented in the southern Precordillera of Mendoza, western Argentina. The lower Paleozoic of this region is mainly characterized by the occurrence of isolated middle and upper Cambrian carbonate blocks chaotically mixed within Middle to Upper Ordovician siliciclastic sequences (Bordonaro,a,b and references therein; Keller.

ORDER PTYCHOPARIIDA Introduction: An large, heterogenous order, classification problematic, with specialized offshoots that are hard to frame within a general diagnosis. Cephalon: typically with opisthoparian facial sutures, with gently forward-tapering simple glabella bearing a broad, rounded front, usually with 3 pairs of rather narrow parallel glabellar furrows; natant hypostome.

Site Information If you are new to the Burgess Shale and wish to see abundant and obvious Cambrian fossils, this is the hike to do. The site is strewn with rock slabs containing appendages of the Cambrian predator Anomalocaris canadensis; trilobites Ogygopsis klotzi, Olenoides serratus and Elrathina cordillerae as well as brachiopods and sponges.

Trilobites typical of the well known Olenellus zone of the Lower Cambrian constitute a large collection from the Eager Formation, near Cranbrook, B.C.

Their classification is discussed and two new species described: Olenellus eagerensis and Olenellus schofieldi Since the use of certain structures in classifying olenellids has been disputed in the past, these and.
