Geography
Country:Canada State/province:Alberta
Coordinates: 50.7° North, 111.5° West (view map)
Paleocoordinates:58.1° North, 76.1° West
Basis of coordinate:stated in text
Altitude:649 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:-9.5 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: not reported
Lithology description: The overlook site occurs in a 1 m thick lithosome of massive-to-highly contorted, fine-grained shelly sandstone. Shells comprise occasional unionid valves in a deposit rich in pisidiid valves and gastropod shells. Compressed, silicified plant fragments measuring up to 10 cm in maximum dimension are present and define poorly developed bedding planes.
Environment:crevasse splay
Glacial or sequence phase:transgressive
Geology comments: Splay deposits typically comprise stacked sequences of interlaminated sands and siltstones separated by erosional surfaces, thus indicating repeated flooding and aggradation.
