Also known as near Hernandarias

Where: Entre Ríos, Argentina (31.3° S, 60.0° W: paleocoordinates 31.4° S, 57.9° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Ituzaingó Formation, Late/Upper Miocene (11.6 - 5.3 Ma)

• With a variable thickness, the LMIF is represented by two sections: 1) the lower conglomerate set, characterised by the presence of fine quartz gravel, and clay and chalcedony clasts, and fossil remains, traditionally known as ‘Mesopotamiense’ or ‘Conglomerado osífero’ (Figure 1C); 2 the upper sets with selected and stratified sands (Brunetto et al. 2013). The lower set contains abundant bones and teeth of continental and marine vertebrates, frequently fragmented and disassociated, with a type of fossilisation very characteristic, i.e. they are well mineralised, hard, heavy, and impregnated with siliceous and ferruginous infiltrations; in addition, they frequently present manganese oxide stains

Environment/lithology: terrestrial; conglomerate

Size classes: macrofossils, mesofossils

Preservation: replaced with silica, replaced with hematite

Collection methods: The specimens presented herein are stored at the Colección de Paleontología de Vertebrados, Centro de Investigación Científica y de Transferencia Tecnológica a la Producción, Diamante, Entre Ríos, Argentina (recognised by the acronym CICYTTP-PV).
