Where: Panama (9.3° N, 79.8° W: paleocoordinates 9.1° N, 78.4° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: lower Gatun Member (Gatun Formation), Tortonian (11.6 - 7.2 Ma)

• thought to be "basal" in section. AGE: Late/Upper Hemingfordian-Early/Lower Barstovian in Gillete (1984). Emended to Tortonian based on more recent dating (Hendy, 2012). Sr dating for nearby sections indicates an age of approximately 11.5 Ma (Hendy, unpublished data)

Environment/lithology: marine; argillaceous claystone

Size classes: macrofossils, mesofossils

Collection methods: bulk, salvage, surface (float), chemical, sieve,

• "site had been exposed by heavy-equipment excavations for a housing development and had lain bare to erosion for several years. Fossil teeth and bones were exposed there along with abundant molluscan remains... Approximately one English ton... of sediment was collected and screen-washed by traditional wet-sieving methods... 25-mesh screen... heavy-liquid sorting" was used
