Paleocoordinates: | 22.9° North, 46.8° East |
Basis of coordinate: | based on nearby landmark |
Time
Period: | Neogene | Epoch: | Miocene |
Stage: | Burdigalian | 10 m.y. bin: | Cenozoic 5 |

Age range of interval: | 20.44000 - 15.98000 m.y. ago |
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 21. | |
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: | macrofossils,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.
All fossil material housed in the Department of Antiquities and Museums at Riyadh. 1 ton of unconsolidated sand and silt from localities 6,8,9 and 21, has been sifted and has produced rodent teeth. | |
Taxonomic list comments:Four orders and 7 genera of fish are recognised 'mainly from localities 7, 9 and 21' but they are not all listed by locality. Those that are listed by locality have been entered on the faunal lists. The others are: Hyperopisus sp., Barbus sp., Labeo sp., Heterobranchus sp., Clarias sp. and Lates sp. |
