Also known as USGS 17690
Where: Panama (9.3° N, 79.8° W: paleocoordinates 8.9° N, 78.1° W)
• coordinate estimated from map
• outcrop-level geographic resolution
When: lower Gatun Member (Gatun Formation), Serravallian (13.8 - 11.6 Ma)
• AGE: Serravallian based on more recent dating (Hendy, 2012). Sr dating for nearby sections suggest an age of approximately 12.5 Ma (Hendy, unpublished data)
• bed-level stratigraphic resolution
Environment/lithology: marine; lithified, medium, concretionary, ferruginous sandstone and conglomerate
•GENERAL: Massive medium-to very fine-grained sandstone and siltstone. Somewhat calcareous, or marly, somewhat tuffaceous, and with a clay-like matrix. The lower part of the formation consists principally of medium-very fine-grained sandstone.
Size class: macrofossils
Preservation: cast, mold/impression
Reposited in the USNM
Collection methods: quarrying,
• Collected by Woodring (1949). 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.
