Springvale (AMNH collection) (Miocene of Trinidad and Tobago)

Where: Trinidad and Tobago (10.4° N, 61.5° W: paleocoordinates 10.2° N, 60.0° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Late/Upper Miocene (11.6 - 5.3 Ma)

• "upper Miocene"

Environment/lithology: coastal; poorly lithified, argillaceous sandstone

• "the bottom was a sandy mud" with "the normal salinity of the open sea" in "relative shallow waters"
• "The matrix, observable on the fossils, is a fine to medium sand with an abundant admixture of clay. No pebbles have been noted." [poorly lithified based on this statment and visible matrix on several figured specimens]

Size class: macrofossils

Collected by Carlos H. Jooss; reposited in the AMNH

• collection was "received from" Jooss

•material apparently was not sieved
