• bed-level stratigraphic resolution

Environment/lithology: "channel"; siliciclastic sediments

• "fluvial channel fill" (Parmley and Holman 2007)

Size classes: macrofossils, mesofossils

Collected by C. E. Rudnick in 1994; reposited in the UNSM

Collection methods: bulk, sieve

• a "sediment screened fauna [was] collected by Rudick (1994)" (Parmley and Holman 2007)
