Domo de Zaza (Miocene of Cuba)

Also known as Zaza Dome; Canal de Zaza

Where: Sancti Spiritus, Cuba (21.6° N, 79.5° W: paleocoordinates 21.9° N, 75.7° W)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Miogypsina-Soriitidae zone, Lagunitas Formation, Early/Lower Miocene (23.0 - 16.0 Ma)

• most in situ fossils are from the lower half of the section

• formation-level stratigraphic resolution

Environment/lithology: fluvial-deltaic; gray, green, yellow, sandy, calcareous conglomerate and bioturbated, paleosol/pedogenic, ferruginous, green, red, sandy claystone

• most in situ fossils are from alluvial sands and gravels; some are from lagoonal clays

•former represent "short term turbulent sheet flow events in a coastal plain setting... [and] True river channel deposits"; latter represent "evanescent cutoff lagoons... no more than moderately saline"

• "poorly sorted, angular to subangular gravel, moderately cemented by carbonates and low in clay content... Grey to yellowish-green interbedded sands and gravels"; "light green clays, with brown and red spotting and minor amounts of sand... soil development... Bioturbation... root casts"

Size class: macrofossils

Collection methods: surface (float), surface (in situ),

• screen washing was attempted but yielded no reported taxa
