south of Empire Mountains (Cretaceous of the United States)

Also known as iguanodont locality

Where: Pima County, Arizona (31.8° N, 110.7° W: paleocoordinates 32.2° N, 70.2° W)

• coordinate stated in text

• small collection-level geographic resolution

When: Shellenberger Canyon Formation (Bisbee Group), Albian (113.0 - 100.5 Ma)

• from the "lowermost suite" of beds, non-marine formation

• bed-level stratigraphic resolution

Environment/lithology: marginal marine; massive, fine-grained sandstone and lithified siltstone

• "These sediments are a nonmarine and nearshore marine facies of the Aptian and Albian sediments described by Stoyanow (1949) near Bisbee."
• "The lowermost suite contains thin marine limestone beds...Fossil tree trunks are abundant in this suite." Bed is described as "Shale, well cemented siltstone and fine grained sandstone; red to dark green to brown; consists of thin beds 1 foot thick to fractured and fissile shales with a massive sandstone bed near the bottom. Dinosaur remains were found in this bed."

Size class: macrofossils

Collected by E. P. Hilton in pre-1958
