NMMNH L-3381, Lucero Uplift (Triassic of the United States)

Where: Cibola County, New Mexico (34.9° N, 107.7° W: paleocoordinates 10.3° N, 46.6° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Bluewater Creek Member (Chinle Formation), Norian (228.0 - 208.5 Ma)

• Upper Bluewater Creek Formation (above McGaffey Member); also referred to as the Bluewater Creek Member of the Chinle Formation. Adamanian LVF, previously considered late Carnian but radiometric dates suggest a Norian age for the Chinle

• bed-level stratigraphic resolution

Environment/lithology: "floodplain"; brown, red, silty mudstone and lenticular, yellow, sandy siltstone

• "we interpret the mudstones as floodplain sediments located near a channel that is represented by the siltstones, which we interpret as bar deposits"
• "red and purple mudstones"; "reddish-brown silty mudstones with intermittent lenses of buff sandy siltstone that contain well-developed cross-laminations and planar crossbeds"

Size class: macrofossils

Collected by R. Dello-Russo in 1996; reposited in the NMMNH
