The formational nomenclature used in the following report is briefly 
as follows: 
Femie formation Jurassic 
Spray River formation (Upper Banff shale) Triassic 
Rocky Mountain quartzite Permian 
Rundle formation (Upper Banff limestone) Pennsylvanian 
and Mississippian 
Banff formation (Lower Banff shale) Mississippian 
Minnewanka formation {J^SSiate'Stoe DeTOnian 
Ghost River formation Age ? 
Cathedral formation Cambrian 
DESCRIPTION OF FORMATIONS EXAMINED 
The work here discussed was undertaken in the summer of 1910 for 
the purpose of determining with greater definiteness and detail the age of 
the various formations downward from the Upper Banff shale to the 
Intermediate limestone inclusive, to distinguish the boundaries between 
them, and to correlate their faunas with those of corresponding formations 
in other parts of America and elsewhere. To this end the formations were 
measured and examined in detail and a representative set of fossils was 
collected from each bed. The work, as it progressed, resolved itself more 
and more into an examination of the Rocky Mountain quartzite down to 
and including the Lower Banff limestone, for it was these formations 
which, in our section, were found to contain large and rather well-preserved 
faunas. No extensive collection had ever been made of these faunas 
which proved surprisingly abundant and comparatively well preserved, 
totalling 102 species. 
Table of Formations 
The rocks of this region are entirely sedimentary; the formations 
studied consist mostly of limestones and calcareous shales. The 
following is a table of the formations: 
Triassic 
Spray River formation (section 1, localities 1-8, and section 3, localities 1-2). Thick- 
ness about 1,500 feet. 
Permian 
Rocky Mountains quartzite (section 1, localities 0-20, 37 (downfaulted). and section 
3, localities 3-4). Thickness about 600 feet (in section 1, 563 feet). 
Pennsylvanian 
Rundle formation (upper part) (section 1, localities 21-36, section 2a, localities 1-14, 
section 2, localities 1-20, section 3, localities 5-10, and section 3a, localities 1-6). 
Thickness about 1,500 feet (in section 2, 1,453 feet). 
Mississippian 
Rundle formation Gower part) (section 2, localities 21-31). Thickness about 600 feet 
(in section 2, 615 feet). 
Banff formation (section 2, localities 32-37 and section 4, localities 1-4). Thickness 
about 1,200 feet (in section 2, 1,175 feet). 
Devonian 
Minnewanka formation (upper part) (section 2, localities 38-42, and section 4, localities 
5-6). Thickness about 1,000 feet (in section 2, 1,050 feet). 
Minnewanka formation (lower part) (section 2, localities 43-47, and section 4, localities 
7-10). Thickness about 1,500 feet. 
Age?
