Also known as M1215

Where: Aleutians East County, Alaska (56.1° N, 157.4° W: paleocoordinates 39.3° N, 96.5° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Staniukovich Formation, Tithonian (152.1 - 145.0 Ma)

• There are numerous good exposures of the Jurassic sequence in the Main Creek anticline, but much of the structure is complicated by faults and subsidary folds. The Staniukovich Formation is around 500 ft thick in this section and comprises siltstone and sandstone. The collection is from about midway up this unit. Portlandian in age = Tithonian

• bed-level stratigraphic resolution

Environment/lithology: marine; brown, gray, green, yellow siltstone and brown, gray, green, yellow sandstone

Size class: macrofossils

Collection methods: quarrying,

• Collections examined by D. Jones (USGS), 1962. Collections are reposited at USGS Menlo Park, or presumably USNM (not reported)
