STRI Loc. 290307, Sample 25 [lower Gatun Fm] (Miocene of Panama)

Also known as Residencia San Judas Tadeo

Where: Colon, Panama (9.4° N, 79.8° W: paleocoordinates 9.1° N, 78.5° W)

• coordinate based on unpublished field data

• small collection-level geographic resolution

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

• STRATIGRAPHIC RELATIONS: From the Gatun Fm, which regionally overlies the Caimito Fm or Mesozoic basement. AGE: Tortonian, on the basis of revised chronostratigraphy (Hendy, unpublished data); direct date is extrapolated from sequence of 87Sr/86Sr data calibrated to stratigraphic height. STRATIGRAPHIC POSITION: From lower member of the Gatun Formation; zone G in composite stratigraphy.

• bed-level stratigraphic resolution

Environment/lithology: coastal; poorly lithified sandstone

• ENVIRONMENT: Shallow-marine, siliciclastic environment.
• SPECIFIC LITHOLOGY: Sandstone, some bioturbation, moderately dense packing of shells. LITHIFICATION: Poorly-lithified, based on observations of material.

Size classes: macrofossils, mesofossils

Preservation: original aragonite

Collected by Hendy in 2011; reposited in the FLMNH

Collection methods: surface (in situ),
