UCLA loc. 6789 (Cambrian of the United States)

Also known as LACMIP loc. 26789; LACMIP 6789 in Lieberman 2001, 2002

Where: Inyo County, California (37.2° N, 118.2° W: paleocoordinates 1.8° S, 99.4° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Fallotaspis trilobite zone, Montenegro Member (Campito Formation), Montezuman (520.0 - 515.3 Ma)

• formation-level stratigraphic resolution

Environment/lithology: marine; lithology not reported

• This collection contained two rock types: a fine-grained gray limestone without identifiable trilobites, and a white limestone with abundant trilobite hash. This latter sample was dissolved in formic acid and yielded a thoroughly deformed suite of small silicified (? )trilobites, indeterminate acrotretid brachiopods, and echinoderm parts.

Size classes: macrofossils, mesofossils

Reposited in the LACM
