Where: Chile (30.3° S, 71.5° W: paleocoordinates 30.4° S, 71.2° W)

• coordinate estimated from map

• local area-level geographic resolution

When: Coquimbo Formation, Calabrian (1.8 - 0.8 Ma)

• Unit 15 was Sr dated at 1.4 Ma, extrapolating the same rate of sedimentation would give a mean age of 1.2 Ma for Unit 16

• group of beds-level stratigraphic resolution

Environment/lithology: transition zone or lower shoreface; lithified sandstone and lithified limestone

Size class: macrofossils
