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,...
Sedimentological and Ichnological Dynamics of the Early Cambrian Mount Clark Formation, Northwest Territories, CanadaDownload
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...
