Time
| Period: | Quaternary | Epoch: | Pleistocene |
| Stage: | Late/Upper Pleistocene | 10 m.y. bin: | Cenozoic 6 |
| Key time interval: | Late/Upper Pleistocene | ||

Stratigraphy
| Formation: | Floral | ||||
| Stratigraphic resolution: | group of beds | ||||
| Stratigraphy comments: from throughout a section about 12 feet thick thought to be of "late Pleistocene age, dating from the time of withdrawal of the Wisconsin ice" based on superposition above a till the hardpan is believed by SkwaraWoolf (1981) to possibly represent the Floral Formation, but the overlying sequence (called by her a "gravel") that yielded most of the fossils does not | |||||
Lithology and environment
| Primary lithology: | coarse conglomeratic sandstone |
| Lithology description: "Coarse angular sand with pebbles and boulders; imperfectly stratified; bones and teeth at base" above and sometimes within a "basal layer of sand, about 0.5 inch in thickness, that has been cemented by calcareous material into a hardpan" and is immediately above a glacial till | |
| Environment: | fluvial indet. |
| Glacial or sequence phase: | late glacial |
| Geology comments: thought to have been deposited "in or near the lake that formed in this area while the ice lay not very far to the northeast" but lithology is only consistent with a fluvial environment | |
Taphonomy
| Modes of preservation: | body |
| Size of fossils: | macrofossils |
| Temporal resolution: | time-averaged |
| Spatial resolution: | allochthonous |
Collection methods and comments
| Collection methods: | salvage,survey of museum collection |
| Reason for describing collection: | general faunal/floral analysis |
| Museum repositories: | ROM |
| Collection method comments: ROM and University of Saskatchewan collections
discovered by "employees of the Dominion Forest Nursery Station... while excavating for sand" and visited by "the writer and his wife" in 1940, although it is not clear whether material was collected during this visit | |
| Taxonomic list comments:fossils may derive from gravel overlying Floral Fm. and therefore may be Wisconsinan or younger (SkwaraWoolf 1981) | |
