Ibadanane Area footprints (Permian of Niger)

Also known as Moradi Fauna, outskirts of Arlit

Where: Agadez, Niger (18.8° N, 7.2° E: paleocoordinates 16.6° S, 8.2° E)

• coordinate estimated from map

• small collection-level geographic resolution

When: Moradi Formation (Izégouandane Group), Changhsingian (254.2 - 252.2 Ma)

• "The locality lies within the upper strata of the Moradi Formation, approximately 25 m below an unconformity at the base of the Téloua 1 Formation [...] The age of the Moradi Formation is poorly constrained, but paleontological evidence indicates a Late Permian age (Taquet, 1972; de Ricqlès and Taquet, 1982). This is based mainly on the presence of the Triassic ichnotaxon Chirotherium in the overlying Téloua 1 Formation (Ginsburg et al., 1966), and on the presence of pareiasaurs and captorhinids in the Moradi Formation, all other known Gondwanan captorhinids also being of supposedly Late Permian age (Modesto and Smith, 2001)." (Damiani, 2006)

• group of beds-level stratigraphic resolution

Environment/lithology: "floodplain"; red mudstone and conglomerate

• "The upper Moradi is composed of three distinctive associations of sedimentary facies which we interpret as having accumulated in discrete sub-environments of the Moradi alluvial plain. They are facies association (A) high sinuousity stream-channel fill and point bar, (B) loessic floodplain and incised distributary channels, and (C) end-point playa." (Smith et al. 2015)
• "All of the late Permian tetrapods recovered to date have come from a 10-m-thick succession of red mudrocks with interbedded gravelly sandstones and rare limestone lenses in the upper Moradi Formation." (Smith et al. 2015)

Size class: macrofossils

Preservation: mold/impression, trace
