Geography

Altitude:664 meters
Geographic resolution:outcrop
Time
Period:Cretaceous Epoch:Late/Upper Cretaceous
Stage:Campanian 10 m.y. bin:Cretaceous 7

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:1.0 m
Local order:bottom to top
Regional section:Dinosaur Park Regional bed:0.166 m
Regional 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 meters above or below the disconformity (Fig. 2, Brinkman, 1990)."
Lithology and environment
Primary lithology:lenticular,"cross stratification",planar lamination,medium,intraclastic carbonaceous sandstone
Lithology description: "BB 51 occurs at the base of a 75 cm thick, 10 m wide, massive sandstone lens within a 3-4 m thick amalgamated IHS sequence (Fig. 7C). The lens erosionally overlies IHS beds and is itself abruptly overlain by IHS. The fossils are present within a thin interval of massive intraclast- and carbonaceous-rich, medium-grained sandstone at the base of the lens. Subhorizontal stratification is present and is delineated by carbonaceous laminae." (Eberth, 1990)
Environment:channel lag
Glacial or sequence phase:transgressive
Geology comments: Characterized as in-channel, coastal plain. Facies association = Inclined heterolithic stratification (IHS) "comprising inclined decimeter-scale sandstone/mudstone interbeds (Thomas et al. 1987), has been interpreted as a lateral accretion deposit in fluvial (Wood, 1985) and tidally-influenced coastal-plain channels (Koster and Currie, 1987; Wood et al., 1988)." 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. (Eberth, 1990)
