Geography
Country: | Jordan |
Coordinates: | 31.6° North, 36.5° East (view map) |
Paleocoordinates: | 15.9° North, 30.2° East |
Basis of coordinate: | estimated from map |
Geographic resolution: | local area |
Time
Period: | Cretaceous | Epoch: | Late/Upper Cretaceous |
Stage: | Maastrichtian | 10 m.y. bin: | Cretaceous 8 |
Key time interval: | Late/Upper Maastrichtian | ||
Age range of interval: | 70.60000 - 66.00000 m.y. ago |
Stratigraphy
Formation: | Muwaddar Chalk Marl | ||||
Stratigraphic resolution: | group of beds | ||||
Stratigraphy comments: Most vertebrate fossils from lowest stratigraphic zone buried beneath 25 meters of sediments. Menuites fresvillensis is a good index taxon for upper Maastrichtian strata Pachydiscus (P.) dossantosi links Jordan with the (upper) lower to lower upper Maastrichtian in the United Arab Emirates/Oman border area and with more poorly constrained Maastrichtian levels in Brazil and Nigeria. The record of Menuites fresvillensis and sphenodiscids suggests correlation of the MCMF with the Emael and Nekum members of the Maastrichtian Formation (ca 66.5–66.1 Ma), plus the upper part of the coeval Kunrade Formation, in the type area of the Maastrichtian Stage (southeast Netherlands, northeast Belgium). However, associated ‘tegulated’ inoceramids from the MCMF are assignable to the group of Tenuipteria argentea (Conrad, 1858), which corroborates the latest Maastrichtian age of that unit and allows correlation with North America and Europe. |
Lithology and environment
Primary lithology: | lithified marl |
Includes fossils? | Y |
Lithology description: Slightly bituminous light gray chalk marl with very large concretions up to 4 meters in diameter rich in vertebrate remains and also containing secondary Uranium and calcite veins. | |
Environment: | offshore indet. |
Geology comments: The predominantly chalky lithology, coupled with the paucity of any diversified benthic macrofaunal assemblages, the absence of erosional surfaces and the presence of diverse planktonic faunas, indicates a moderate to deep-water pelagic environment (Powell 1989). On the basis of macrofossil evidence at a number of localities, inclusive of sclerorhynchid saw fishes and ginglymostomatid sharks, palaeowater depth is estimated not to have exceeded 100 metres, under prevailing subtropical palaeoclimatic conditions (Kaddumi 2009a). |
