Also known as USGS# 6236

Where: Panama (9.3° N, 79.9° W: paleocoordinates 9.1° N, 79.0° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Toro Limestone Member (Chagres Sandstone Formation), Messinian (7.2 - 5.3 Ma)

• STRATIGRAPHIC RELATIONS: Chagres Sandstone overlies and partly overlaps the Gatun Fm. Calcareous strata at the abse of the formation throughout most of the outcrop area in the Canal Zone constitute the Toro Limestone Mbr. The unit is as much as 1000 ft thick. AGE: Late Miocene (late Tortonian-Messinian) according to Collins and Coates 1999); more likely that entire unit accumulated in Messinian part of late Miocene.

• bed-level stratigraphic resolution

Environment/lithology: shallow subtidal; poorly lithified, medium-grained, coarse, shelly/skeletal, sandy limestone

Size class: macrofossils

Reposited in the CAS, PRI, USNM

Collection methods: quarrying,

• COLLECTOR: D.F. MacDonald (1912). RESPOSITORIES: Material is also held (but not specified for any specific collection) at Stanford University, Acad. Nat. Sci. Phil., Cornell University, PRI, U. Cal. and Cal. Acad. Sci.
