Pipestone Creek Bonebed (RTMP) (Cretaceous of Canada)

Also known as ETE Locality 1574, TMP.1989.55, Tanke Site 11, Pachyrhinosaurus bonebed

Where: Alberta, Canada (55.1° N, 119.1° W: paleocoordinates 63.8° N, 81.6° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Unit 3 Member (Wapiti Formation), Late/Upper Campanian (83.5 - 70.6 Ma)

• ETE dating method: time_unit, ETE age comment: 0 radiometric intage_min; approx 73 ma

• bed-level stratigraphic resolution

Environment/lithology: crevasse splay; poorly lithified, intraclastic, carbonaceous siltstone and unlithified, fine-grained, white sandstone

• "The bones occur within a relatively soft dark carbonaceous siltstone that is at least 4 m thick...This level contains occasional clay balls and may represent a crevasse splay. The bone bed matrix contains many comminuted plant fragments, compressed carbonized wood branches and logs, and seeds...Pieces of hard and clear fossil resin, some greater than 5 mm in diameter, are abundant throughout the bone layer."

Size classes: macrofossils, mesofossils

Preservation: concretion, amber

Collected by A. Lakusta in 1972, 1974, 1983, 1986–1989; reposited in the TMP

Collection methods: quarrying, surface (float), surface (in situ), mechanical,

• ETE reference list: 990, 666
