Geography
Country:Canada State/province:Alberta
Coordinates: 50.8° North, 111.3° West (view map)
Paleocoordinates:58.1° North, 75.8° West
Basis of coordinate:stated in text
Altitude:646 meters
Geographic resolution:outcrop
Time
Period:Cretaceous Epoch:Late/Upper Cretaceous
Stage:Campanian 10 m.y. bin:Cretaceous 7
Key time interval:Middle Campanian
Age range of interval:83.60000 - 72.10000 m.y. ago
Stratigraphy
Geological group:Belly River Formation:Oldman
Local section:DPP-Brinkman Local bed:-5.5 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:lenticular,very fine,fine silty,carbonaceous sandstone
Lithology description: BB 103 occurs in a 1.25 m thick contorted, silty very fine-to-fine-grained sandstone with small lenses of medium-grained sandstone, carbonaceous plant fragments and microfossils.
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.
Taphonomy
Modes of preservation:body
Degree of concentration:concentrated
Size of fossils:macrofossils,mesofossils
Preservation of anatomical detail:good
Disassociated major elements:some
Disassociated minor elements:many
Size sorting:medium
Fragmentation:occasional
Temporal resolution:time-averaged
Spatial resolution:autochthonous
Collection methods and comments
Collection methods:bulk,surface (float),sieve,field collection
Minimum sieve size:64.000 Maximum sieve size:81.000
Reason for describing collection:paleoecologic analysis
Museum repositories:TMP
Collectors:E. Nicholls Collection dates:2 July 1990
Collection method comments: Screenwashed elements were collected using a screen with 9 openings per centimeter.
