Paleocoordinates:	49.6° North, 91.9° West
Basis of coordinate:	stated in text
Geographic resolution:	outcrop

Time

Period:	Paleogene	Epoch:	Eocene
Stage:	Ypresian	10 m.y. bin:	Cenozoic 2

Stratigraphy

Formation:	Willwood
Local section:	Clark	Local bed:	1750 m
Local order:	bottom to top
Stratigraphic resolution:	group of beds
Stratigraphy comments: "zone Wa-2 of Gingerich, 1983" the Bird Quarry lens "varies from 10-20 cm in thickness" and the Calcirudite Site is another lens that outcrops "some 10 m higher stratigraphically" and has "a maximum thickness in placs of 30-40 cm"

Lithology and environment

Primary lithology:	lenticular,desiccation cracks,bioturbation lithified wackestone
Secondary lithology:	concretionary unlithified "carbonate"
Includes fossils?	Y
Includes fossils?	Y
Lithology description: all Bird Quarry fossils are from a lens "within a bed of gray mudstone" that "is a complex mass of brecciated, bioturbated micrite with some spar-filled dessication cracks and rare spar-filled gastropods... distinct [silt-filled] burrows and networks of plant rootlets" whereas "the calcirudite bed is composed of rounded calcium carbonate nodules equivalent in grain size to coarse sand" and "grades upward into a thin platy sandstone"
Environment:	wet floodplain
Geology comments: lines of evidence "suggest [the Bird Site had] a pedogenic origin involving accumulation or precipitation of calcium carbonate in a shallow intermittently flooded depression... Bird Quarry is similar [to the Discovery Site] in some respects, but different in the [tabular or sheet-like] shape of the whole deposit, the rarity of snails, the size and freshness of burrows, and the presence of an extensive network of rootlets... the calcirudite [site] probably involved reworking of soil nodules by a more ephemeral transisent stream"
