Al-Sarrar, Locality 5, Dam Formation (Miocene of Saudi Arabia)

Where: Saudi Arabia (26.0° N, 49.4° E: paleocoordinates 22.6° N, 46.5° E)

• coordinate based on nearby landmark

When: Dam Formation, Early/Lower Miocene (23.0 - 16.0 Ma)

• Late Early Miocene. 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

• 'The lithologies, sedimentary structures (presence of palaeocurrents in loc. 6 and 8), the character of the fauna exclusively continental and the deposition laid down into low energy zone (specially in loc. 6 and 8 explaining the scarcity of small vertebrates and the association of postcranial bones) suggest a fluviatile environment.'
• No lithology given for locality 5.

Size class: mesofossils

Collection methods: bulk,

• Al-Sarrar localities 4-9 and 11-24 can all be dated within a short period of time. Localities 5,6,7,8, and 9 are considered contemporaneous.

•All fossil material housed in the Department of Antiquities and Museums at Riyadh.
