Catavi vertebrate and mollusc fauna at Seripona (Devonian of Bolivia)

Where: Bolivia (18.5° S, 64.8° W: paleocoordinates 64.9° S, 99.5° W)

• coordinate based on political unit

• outcrop-level geographic resolution

When: Catavi Formation, Early/Lower Devonian (419.2 - 393.3 Ma)

• Although formation has been called Silurian based on sedimentological criteria, vertebrates suggest Lower Devonian, even Late Lower Devonian, age.

• formation-level stratigraphic resolution

Environment/lithology: marginal marine; shale and black limestone

• Based on fauna, authors infer tidal marsh environment.
• "Near top of [Kirusillas Formation, which consists of grey to black lutites] are intercalations of green lutites and grey-green sandstone layers which mark the transition to the Catavi Formation. The latter is a 456 m. thick succession of lutites and lenses of black limestone with cone-in-cone structures. The bone-bed described herein has been found in the upper part of this formation."
