Stratigraphy
Formation: | Dam | ||||
Stratigraphy comments: 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. |
Lithology and environment
Primary lithology: | not reported |
Lithology description: No lithology given for locality 5. | |
Environment: | fluvial indet. |
Geology comments: '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.' |
Taphonomy
Modes of preservation: | body |
Size of fossils: | mesofossils |
Collection methods and comments
Collection methods: | bulk,field collection |
Reason for describing collection: | general faunal/floral analysis |
Collection method comments: 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. |
