| Country: | Sudan |
State/province: | Ash Shamaliyah |
| Coordinates: |
16.7° North, 31.1° East (view map) |
| Paleocoordinates: | 2.6° South, 32.2° East (Wright 2013) |
| Basis of coordinate: | stated in text |
| Geographic resolution: | local area |
| Period: | Cretaceous |
Epoch: | Late Cretaceous |
| Stage: | Campanian - Maastrichtian |
10 m.y. bin: | Cretaceous 7 - Cretaceous 8 |
| Key time interval: | Campanian - Maastrichtian |
| Age range of interval: | 83.6 - 66 m.y. ago |
| Formation: | Wadi Milk |
| Stratigraphic resolution: | bed |
Stratigraphy comments: Traditionally been regarded as Cenomanian (e.g. Buffetaut et al. 1990; Rage and Werner 1999), but more recent work suggests that this age should be revised to the Campanian–Maastrichtian (Klein et al. 2016; Salih et al. 2016)
Agyemang et al. 2019: A maximum depositional age of 79.2 ± 2.4 Ma is demonstrated herein for the youngest detrital zircon population in the Wadi Milk Formation |
| Primary lithology: | "cross stratification",coarse sandstone |
| Secondary lithology: | fine siltstone |
| Includes fossils? | Y |
| Lithology description: "fine grained siltsones, sandstones, and corase cross-bedded sandstones" |
| Environment: | fluvial-lacustrine indet. |
| Geology comments: "The Wadi Milk Formation is dominated by sediments of braided rivers and sandy braided-meandering river systems...The sedimentary sequence is interpreted as deposits of meandering rivers with dominating flood plain and lacustrine environments, minor fluviatile intercalation and rare paleosols." |
