Ojo Huelos Spring, NMMNH L-354 (Triassic of the United States)

Also known as Hubble Bench

Where: Valencia County, New Mexico (34.6° N, 106.8° W: paleocoordinates 9.6° N, 45.8° W)

• coordinate stated in text

• small collection-level geographic resolution

When: Ojo Huelos Member (San Pedro Arroyo Formation), Late/Upper Triassic (237.0 - 201.3 Ma)

• three separate beds; given as late Carnian (Adamanian LVF) but is correlated with the Bluewater Creek Member of Arizona, suggesting that it might be Norian in age.

• group of beds-level stratigraphic resolution

Environment/lithology: lacustrine; gray, yellow, sandy mudstone and gray, yellow limestone

• "clastic sediment-starved lacustrine deposits" with no evidence of pedogenesis
• "The fossiliferous horizons are, in ascending order, a mottled, dark yellowish-orange to yellowish-brown pisolitic limestone (A), a yellowish-gray sandy mudstone with thin limestone ledges (B), and a dusky yellow to light gray pisolitic limestone (C)."

Size classes: macrofossils, mesofossils, microfossils

Collected by S. Lucas, K. Kietzke, A. Heckert; reposited in the NMMNH
