Al-Sarrar, Locality 22, Pollen level 256/1, Dam Formation (Miocene of Saudi Arabia)

Where: Saudi Arabia (26.0° N, 49.4° E: paleocoordinates 22.9° N, 46.8° E)

• coordinate based on nearby landmark

When: Dam Formation, Burdigalian (20.4 - 16.0 Ma)

• Late Early Miocene.

•The pollen level (sample no 256/1) has not been correlated with main fossil localities, although not stratigraphically distant.

•Formation is Burdigalian in age, see Chan et al. 2017 and Ali et al. 2021 for despotional history of Dam Formation.

•There are 3 Formations in the succession - the Hadruck, Dam and Hofuf (Hofuf overlies the others). Type section of the Dam Formation is Jabal al Lidam. The depth of the formation at Al-Sarrar varies, but is around 30m. Near the Arabian Gulf the Formation is entirely marine, with more continental facies inland. The Al-Sarrar area is an area of 'continental sediments interbedded with the marine series'.

•Fauna has been collected from a number of localities which have been entered individually.

Environment/lithology: fluvial; lithology not reported

• 'Greenish clay silt deposit'

Size class: microfossils
