Where: Bocas del Toro, Panama (9.1° N, 81.6° W: paleocoordinates 9.0° N, 81.1° W)
• coordinate estimated from map
When: Escudo de Veraguas Formation, Piacenzian (3.6 - 2.6 Ma)
• Overlying Unit: Not exposed. Underlying Unit: Not exposed. Thickness: About 131 m. (LeBlanc 2021).
Environment/lithology: offshore; burrowed, gray, blue siltstone and burrowed, silty claystone
• The formation as a whole represents offshore siliciclastic shelf sediments deposited at palaeobathymetries of 100-150 m. It is likely that it was muddy bathyal in latest Miocene; inner to middle neritic, carbonate shoal or reef in early to middle Pliocene; and carbonate influenced, muddy outer neritic in middle to latest Pliocene (Collins 1993; Todd and Collins., 2005; Collins et al., 1993; Coates et al., 2005; LeBlanc 2021).
• This location is in the upper part of the Escudo de Veraguas Formation. The upper part of the Escudo de Veraguas Formation (Section 10 of Coates (1999)) consists of about 8 m of blue-gray, clayey siltstone and silty claystone, sparsely shelly and intensely burrow-mottled. Thalassinoid-type burrows are common, as are echinoids. Two distinctive marker beds within this section consist of slightly more indurated burrow zones, suggesting minor disconformities or slower depositional rates. (LeBlanc 2021).
