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.
Etymology
The formation is named after Mount Kurek (2,280 metres (7,480 ft)), near Langar, Uzbekistan.
Description
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.
