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. Formation is Burdigalian in age, see Chan et al. 2017 and Ali et al. 2021 for despotional history of Dam Formation. |
Lithology and environment
| Primary lithology: | not reported |
| Lithology description: No lithology given for locality 14. | |
| 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.
All fossil material housed in the Department of Antiquities and Museums at Riyadh. | |
| Taxonomic list comments:Cf. Schweboemys sp. may possibly be from this locality. | |
