Alberta Farrow Well (Deadwood Fm) - 8776 ft (Cambrian of Canada)

Where: Alberta, Canada (50.7° N, 113.4° W: paleocoordinates 5.2° S, 80.4° W)

• coordinate estimated from map

• hand sample-level geographic resolution

When: Deadwood Formation, St Davids (509.0 - 497.0 Ma)

• AGE: Marjuman (late Middle to early Late Cambrian) in age. Correlates to upper St Davids.

•SPECIFIC COMMENTS: Collected from 8776 ft below surface. Lowermost sample collected.

• bed-level stratigraphic resolution

Environment/lithology: shallow subtidal; limestone and siliciclastic

• Deposited in a shallow intracontinental sea shoreward of the passive margin of western Laurentia.
• Limestone beds, intercalated within a succession of sandstones, siltstone, and shales.

Size class: macrofossils

Preservation: replaced with phosphate

Reposited in the GSC

Collection methods: core, chemical, acetic, sieve,

• Limestone samples were dissolved in 10% acetic acid. Insoluable residues were screened using 200 mesh (75 micron opening) sieves, then separated in tetrabromethane at specific gravity of 2.85. Conondonts and phosphatic shelled brachiopods were handpicked from the residue. Figured specimens are deposited at the Geological Survey of Canada (GSC), Alberta, Canada
