Iggui Aouglef tracksite (Triassic of Morocco)

Where: Marrakech-Tensift-Al Haouz, Morocco (30.8° N, 9.1° W: paleocoordinates 1.8° N, 1.2° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Tanameurt Member (Timezgadiwine Formation), Olenekian (251.2 - 247.2 Ma)

• orig. dated as Late Permian on vertebrate remains and assigned to upper part of T2 unit, but actually basal T3

• bed-level stratigraphic resolution

Environment/lithology: alluvial fan; massive, medium-grained, brown, red, conglomeratic sandstone and brown, red, silty mudstone

• "This facies association is interpreted as overbank deposits laid down under lower flow regime, in middle alluvial fan setting."
• "...interbedded light brown to light red sheet sandstone and red to chocolate sandy mudstone, with some mudcracks, are frequent. The very coarse- to medium-grained sandstone facies dominate. They are composed of horizontal laminated, subordinate ripple laminated, or massive layers."

Size class: macrofossils

Preservation: cast, trace

Collection methods: surface (in situ),
