La fauna de Santa Rosa (Pliocene of Mexico)

Where: Veracruz, Mexico (21.4° N, 98.1° W: paleocoordinates 21.6° N, 97.4° W)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Early/Lower Pliocene (5.3 - 3.6 Ma)

• Unknown lithostratigraphic data. Table of known taxon biostratigraphic distribution suggests a Pliocene age. Amussium mortoni, Anomia simplex, Laevicardium sublineatum, and Ficus [Pyrula] papyratia are all know from the Yorktown and Waccamaw Formations = Early Pliocene. Text also suggests an "inferior Pliocene" age, though does not discount Miocene age.

• formation-level stratigraphic resolution

Environment/lithology: marine; siliciclastic sediments

• Unknown environmental and geologic data
• Unknown lithologic data. Seems likely to be from siliciclastic lithologies.

Size class: macrofossils

Collection methods: Missing supplementary information as text is in spanish. Will derive this at a later stage. Unknown museum repositary for this collection
