Rainy Day Site, RTMP L1140 (Cretaceous of Canada)

Also known as RDS

Where: Alberta, Canada (49.2° N, 110.7° W: paleocoordinates 56.4° N, 76.2° W)

• coordinate stated in text

• small collection-level geographic resolution

When: Upper Member (Oldman Formation), Late/Upper Campanian (83.5 - 70.6 Ma)

• Nesmo's unit; 5.5 m higher than CBC site; upper member of formation

• bed-level stratigraphic resolution

Environment/lithology: channel lag; lenticular, intraclastic, argillaceous sandstone

• "lower 1.5 m of a 4.5 m thick multistory, lenticular sandstone body (representing a paleochannel deposit). Vertebrate fossils in RDS are associated with fragmentary to complete unionid valves, contorted mudstone, fine-grained sandstone, caliche clasts, and shale rip-ups, along with large unidentified dinosaurian skeletal fragments. The RDS lithostone represents a stacked succession of lags, and passes up into medium- to large-scale cross beds."

Size classes: macrofossils, mesofossils

Collected in 1996, 2013; reposited in the TMP

Collection methods: bulk, sieve,
