La Angostura section (Neogene of Bolivia)

Where: Bolivia (18.2° S, 63.5° W: paleocoordinates 18.3° S, 61.6° W)

• coordinate stated in text

• small collection-level geographic resolution

When: Tariquía Formation, Huayquerian (8.0 - 5.0 Ma)

• Soibelzon et al. 2020: Tariquía Formation is considered Huayquerian in Age (Middle to Late Miocene) because of the fossil record in other locations were Tariquia Fm is reported and as late Miocene due to fission tracks in apatites (Moretti et al., 1996).

• formation-level stratigraphic resolution

Environment/lithology: fluvial; massive mudstone and massive, lenticular sandstone

• Soibelzon et al. 2020: Regarding the paleoenvironment represented by the Tariquía Fm., Soibelzon et al. (2019) observed that in most of the formations where Cyonasua was recorded, paleoenvironmental analyses indicate in- creasing aridity, presence of water bodies and some degree of tree cover. This is in agreement with the proposed paleobiology of Cyonasua (see Tarquini et al., 2017). Accordingly, Poiré et al. (2016) proposed warm climates and humid environments with abundant water bodies, vegetation and trees for the Tariquia Fm. Based on the record of snakes (Boidae, Serpentes) and viscachas (Lagostomus, Rodentia).
• Soibelzon et al. 2020: Most of the specimens were unearthed from massive muddy facies (paleosols) and to a lesser extent in sandstone beds with lenticular geometry, both massive and cross-bedded (fluvial channels).

Size class: macrofossils

Collection methods: Soibelzon et al. 2020: specimen housed at Yacimientos Petrolíferos Fiscales Bolivia, Centro de Tecnología Petrolera—Litoteca—Colección de Paleontología, Santa Cruz de la Sierra, Bolivia.
