The Kurek Formation (Russian: Kurek Svita) is a late Oxfordian (Late Jurassic) geologic formation of the Kugitang Svita in Turkmenistan and Uzbekistan. Fossil sauropod tracks have been reported from the formation.[1]
Etymology
[edit]The formation is named after Mount Kurek (2,280 metres (7,480 ft)), near Langar, Uzbekistan.[2]
Description
[edit]The mudstones and limestones of the formation comprise a 2 centimetres (0.79 in) thick, massive micrite (mudstone) with sporadic and poorly preserved thin-walled bivalves. Also tracks were preserved at that were probably made in shallow water, showing, in some parts, ripple marks.[3]
Fossil content
[edit]Among the following fossils have been found in the Kurek Formation:[4]
- Dinosaurs
- Ichnofossils
- Megalosauripus uzbekistanicus
- Mirsosauropus tursunzadei
- Regarosauropus manovi
- Shirkentosauropus shirkentensis
- Therangospodus pandemicus
- Invertebrates
