Paraje Solo [Agueguexquite Fm] (Pliocene of Mexico)

Where: Veracruz, Mexico (18.2° N, 94.4° W: paleocoordinates 18.2° N, 93.8° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Agueguexquite Formation, Late/Upper Pliocene (3.6 - 2.6 Ma)

• STRATIGRAPHIC RELATIONS: Not stated in the text, but presumably from the Agueguexquite Formation. From other sources: overlies the Upper Conception and Filisola Fms (Early-Late Pliocene) according to Collins and Coates (1999, p. 75), and is equivalent to the Tirabuzon Fm of Mexico's Maria Madre Island, and Esmeraldas of NW Ecuador. AGE: Late Pliocene; recent descriptions of fauna from the Agueguexquite Fm assign it to the Pliocene, more specifically the middle Pliocene (N20). This also matches revised ages for the Bowden Fm. Late Pliocene according to Collins and Coates (1999, p. 75). STRATIGRAPHIC POSITION: From unknown position in formation.

• formation-level stratigraphic resolution

Environment/lithology: coastal; unlithified, micaceous, shelly/skeletal, gray, blue, carbonaceous claystone

• No geologic or paleoenvironmental data reported in text.
• SPECIFIC LITHOLOGY: The sediments consist principally of bluish grey sandy clays, mostly micaceous, with intercalations of grit and sand, poorly bedded, containing a rich fauna of gastropoda and lamellibrancha, and scatterd plant remains. The very base of the unit has layers of quartz pebbles, from hazelnut to walnut in size. LITHIFICATION: No lithification data is reported, however all figured specimens show no evidence of lithified matrix and therefore this collection is assigned as unlithified.

Size class: macrofossils

Collection methods: surface (in situ),

• COLLECTOR: Unknown. REPOSITORY: Unknown.
