PBDB Collection

Fauna x, Section AV4, Delorme Fm., Mackenzie Mts. (Silurian of Canada)

Where: Northwest Territories, Canada (62.4° N, 127.0° W)

• Paleocoordinates: 1.0° N, 99.5° W (Wright 2013)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Delorme Formation, Wenlock (433.4 - 427.4 Ma)

• Zonation based on conodonts present in AV sections 1, 2, and 4. (AV 3 and DR sections correlated with these on basis of trilobite faunal assemblages. I'm assuming AV5 can be correlated as well.) See PBDB ref. 7215. This fauna is between j (early Wenlock) and k (upper Wenlock/lower Ludlow).

• bed-level stratigraphic resolution

Environment/lithology: slope; argillaceous limestone and shale

• Grand Cycle 3.

•SEP environmental call based primarily on PBDB ref. 7215.

• "...sequence of buff and light brown weathering, thinly bedded limestones, dolomites and shales that overlie the Whittaker Formation and underlie the Camsell Formation...The beds above and including a distinctive buff-brown shale unit in the sections near Avalanche Lake are included in the Delorme Formation in this work, although the lowest buff-brown shaly beds (below distinctive orange coloured limestones and dolomites) could be regarded as transitional between the Road River and Delorme..." (PBDB ref. 7215)

Preservation: replaced with silica
