Ar Rubay'iyah (2007 coll) (Triassic of Saudi Arabia)

Where: Saudi Arabia (26.4° N, 44.2° E: paleocoordinates 19.8° S, 41.2° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Jilh Formation, Ladinian (242.0 - 237.0 Ma)

• Jilh Formation is late Anisian-lowermost Carnian

• group of beds-level stratigraphic resolution

Environment/lithology: paralic; lithified, dolomitic sandstone

• Lithological features imply sediment deposition under paralic marine conditions (tidal flats). Inter-bedded fluvial sands and clayey strata at the bottom of the dolomitic series are thought to derive from estuarine outlet channels (Sharief 1986). The upper carbonate beds represent a restricted evaporitic lagoon complex bordering a shallow offshore shelf (Sharief 1986).
• Isolated vertebrate bones and teeth occur randomly throughout thick carbonate beds near the base of the main dolomitic sandstone sequence

Size class: macrofossils

Collected by Joint Saudi-Australian field team in 2007

• Repository: Saudi Geological Survey (SGS), Jiddah, Kingdom of Saudi Arabia
