Where: Manabi, Ecuador (0.2° S, 80.3° W)

• Paleocoordinates: 0.0° N, 79.8° W (Wright 2013)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Punta Ballena Member (Jama Formation), Early/Lower Pleistocene (2.6 - 0.8 Ma)

• While not specified, it appears that the collection is a composite of several bulk samples showing similar taphonomic characteristics and stratal position. Early Pleistocene in age (MOI stages 35-50). The Punta Ballena Member of the Jama Formation is overlain by the El Matal Member (60 m thick, fluvial) and underlain by the Punta Pasa Borracho Member (20 m thick, marine). The Punta Ballena Member is 100 m thick, mixed fluvial and marine. The age of the Jama Formation is constrained by 40Ar/39Ar date of tephra beds.

• group of beds-level stratigraphic resolution

Environment/lithology: shoreface; unlithified, medium-grained, coarse, shelly/skeletal sandstone

Size class: macrofossils

Preservation: original aragonite, original calcite

Collection methods: bulk, sieve,

• Unknown respository for material; possibly either Universita di Camerino or Universita di Pisa, Italy; faunal list is a composite of multiple bulk collections.
