Fall 2018
Banded iron formations (BIF) are a key chemical sedimentary record for examining the evolution of the early oceans, atmosphere, and biosphere. While the classic model suggests that BIF were deposited by either anoxygenic photoferrotrophs or oxygen producing cyanobacteria, recent studies have...

Interpretation of sponge fossil faunas: A neontological approach to a paleontological problem
DownloadFall 2021
The tempo and mode of early animal evolution remains one of the biggest conundrums in biology. Stratigraphy shows that there is a gap, not attributable to poor preservation, of at least ~100 Myr between the oldest animal fossils and the divergence times implied by molecular phylogenies. Sponges,...

Yoho National Park protects the Burgess Shale: a chain of fossil beds in British Columbia bearing what paleontologist and science writer Stephen Jay Gould once called “the world’s most important animal fossils.” They are an extraordinary record of underwater soft-bodied organisms from just after...

Fall 2019
The Alberta basement is part of the North American craton, which has been stable since Proterozoic and is also known as Laurentia. Geophysical and geology studies in Alberta have revealed that the basement rocks of Alberta have been assembled by complex tectonic events, such as subduction,...

Sedimentological and Ichnological Dynamics of the Early Cambrian Mount Clark Formation, Northwest Territories, Canada
DownloadSpring 2017
The early Cambrian Mount Clark Formation of the Northwest Territories comprises marginal marine to marine siliciclastic sediments deposited in an incipient rift basin on the margin of Laurentia. Within core and outcrop datasets the preserved record of sedimentation represents complex and highly...

Subsurface Analysis and Correlation of Cambrian Formations Beneath the Colville Hills, Northern Mainland, Northwest Territories
DownloadSpring 2018
The Lower and Middle Cambrian succession in the Colville Hills region, Northwest Territories consists of the Mount Clark, Mount Cap and Saline River Formations, which were deposited in an epicontinental basin. Significant research had been conducted over the last hundred years to better...

Zinc in Precambrian iron formations: The record, partitioning, diagenetic effects and implications for eukaryotic metallome evolution
DownloadFall 2013
Zinc is amongst the most important trace elements for eukaryotes. Previous work has suggested it to have been at biolimiting concentrations for much of the Precambrian, thereby limiting eukaryotic evolution. Yet, the iron formation (IF) record, a critical proxy for paleomarine conditions, has...
