Dog Pond Area (Lar 6) (Cretaceous of the United States)

Also known as DMNH loc. 3319

Where: Weld County, Colorado (40.8° N, 104.5° W: paleocoordinates 47.3° N, 80.2° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Laramie Formation, Lancian (70.6 - 66.0 Ma)

• group of beds-level stratigraphic resolution

Environment/lithology: "channel"; sandstone

• "light orange, weathered sandstone beds [with] large-scale, lateral accretion planes (up to 3 m high), and extensive soft-sediment deformation near the axis and thickest parts of the multi-storey channel. Planar- and trough cross-stratification are present at the base of this channel body where the bedding is not distorted... coarse to fine sand and the sorting is moderate... Lar 5 is situated in the coarse-grained basal lag of the oldest channel, and Lar 6 is at the storey break"

Size classes: macrofossils, mesofossils

• "A tyrannosaurid phalanx, hadrosaurid metatarsal, turtle shell pieces, and microvertebrate fossils have been recovere"

Reposited in the DMNH
