UCMP loc. 3042 (Miocene of the United States)

Also known as possible equivalent to UCMP loc. V-4825 (see Downs 1956)

Where: Wheeler County, Oregon (44.5° N, 119.7° W: paleocoordinates 44.3° N, 114.6° W)

• coordinate stated in text

When: Mascall Formation, Barstovian (16.3 - 12.5 Ma)

Environment/lithology: terrestrial; tuffaceous, white sandstone and brown conglomerate

• The south face of the 3,240 foot-ridge at locality 3042 presents exposures of white tuffaceous sediments overlain by coarse gravels and brownish tuffs or clays...In each case the specimens were found lying on the white tuffaceous sediments distinctly below the brownish beds with coarse gravels which are exposed in the upper portion of the section. There is reason for believing that the teeth were originally embedded in the white deposits.

Size class: macrofossils

Preservation: original phosphate
