Fluvial and eolian ichnofaunas from the Lower Permian of South America (Patquía Formation, Paganzo Basin)

The Lower Permian Patquía Formation is the youngest unit of the Paganzo Basin, western Argentina. The lower section consists of red mudstones, and fine- and coarse-grained sandstones deposited in fluvial systems with extensive and thick floodplain deposits. These rocks contain a low-diversity and re...
