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:83.50000 - 70.60000 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.
