Also known as USGS #8405
Where: Panama (9.1° N, 80.0° W: paleocoordinates 9.0° N, 79.0° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Toro Limestone Member (Chagres Sandstone Formation), Messinian (7.2 - 5.3 Ma)
• From Olsson's Anomia zone limestone. 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); Messinian age is more probable.
• 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,
• Collected by A.A. Olsson (1918). 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.
