Where: Panama (9.0° N, 79.6° W: paleocoordinates 8.4° N, 77.5° W)

• coordinate stated in text

• small collection-level geographic resolution

When: Cucaracha Formation, Hemingfordian (20.4 - 16.0 Ma)

• upper levels of the Cucaracha Formation, close to the contact with the overlying Pedro Miguel Formation; c. 18.8 Ma

•

•Underlying Culebra Fm. Contains LMA dated to Hemingfordian-Barstovian ages. Mammal fossils within the Cucaracha Formation span SALMA ages of latest Arikareean to middle Barstovian, with a middle Hemingfordian age being most likely (Kirby et al. 2008). Magnetostratigraphical and radiometric dating of a marker tuff bed of the Cucaracha Formation indicate an age between 19.05 and 18.78Ma (early Miocene) for both the uppermost Culebra and Cucaracha formations (MacFadden et al. 2014).

• bed-level stratigraphic resolution

Environment/lithology: channel lag; conglomerate
