Geography
Country: | Canada | State/province: | Alberta |
Coordinates: | 50.8° North, 111.6° West (view map) | ||
Paleocoordinates: | 58.1° North, 76.2° West | ||
Basis of coordinate: | stated in text | ||
Altitude: | 671 meters | ||
Geographic resolution: | outcrop |
Time
Period: | Cretaceous | Epoch: | Late/Upper Cretaceous |
Stage: | Campanian | 10 m.y. bin: | Cretaceous 7 |
Key time interval: | Late/Upper Campanian | ||
Age range of interval: | 83.60000 - 72.10000 m.y. ago |
Stratigraphy
Geological group: | Belly River | Formation: | Dinosaur Park | ||
Local section: | DPP-Brinkman | Local bed: | 38.0 m | ||
Local order: | bottom to top | ||||
Stratigraphic resolution: | bed | ||||
Stratigraphy comments: Microvertebrate sites of Brinkman (1990) are "...placed in stratigraphic sequence by reference to a disconformity located about sixty meters below the base of the Lethbridge Coal (Eberth, 1990). The stratigraphic position of each site is expressed in terms of meteres above or below the disconformity (Fig. 2, Brinkman, 1990)" where positive numbers are above and negative below. |
Lithology and environment
Primary lithology: | current ripples,intraclastic sandstone |
Lithology description: "BB 108 occurs at the base of a fining-upward 4-5 m thick lithosome comprising, in ascending order, 20 cm of fossilifoerous, intraclast-rich sandstone (BB 108), 50 cm of ripple-laminated, fine-to-medium-grained sandstone (Fig. 6F), 2 m of thinning-upward sets of large scale TCSS, and 1.5-2.5 m of IHS.... Vertebrate microfossils and mudstone intraclasts are poorly sorted within the basal intraclast deposit. Clast long axes are oriented subhorizontally and range up to 6 cm (Fig. 6G)." (Eberth, 1990) | |
Environment: | channel lag |
Glacial or sequence phase: | transgressive |
Geology comments: Characterized as in-channel, coastal plain. Facies association = trough cross-stratified sandstones. Upper flow-regime, tractional plane beds fromed during flood stage. Lag deposits, or plane bed deposits that show horizontal-planar stratification, bed thicknesses exceeding single pebble diameters, normal graded or fining upward texture, and matrix-supported clasts. The disconformity in southern Alberta records a Cordilleran uplift event west of the Park. |
