WThe Balabansai Formation is a geological formation in Kazakhstan, Kyrgyzstan and Uzbekistan whose strata date back to the Bathonian and Callovian stages of the Middle Jurassic. Dinosaur remains are among the fossils that have been recovered from the formation. The lithology primarily consists of variegated sandstones, siltstones, claystones, and rare gravels and marls. Many taxa have been found in the formation, including amphibians and mammals
WThe Bissekty Formation is a geologic formation and Lagerstätte which crops out in the Kyzyl Kum desert of Uzbekistan, and dates to the Late Cretaceous Period. Laid down in the mid to late Turonian, it is dated to about 92 to 90 Ma.
WThe Ialovachsk or Yalovach Formation is a Santonian geologic formation in Kyrgyzstan, Tajikistan and Uzbekistan. Fossil dinosaur eggs have been reported from the formation.
WThe Khodzhakul Formation is a Cenomanian aged geologic formation in Uzbekistan. Dinosaur remains are among the fossils that have been recovered from the formation. As well as those of Mammals. It is part of the same stratigraphic succession as the overlying Bissekty Formation.
WThe Kugitang Formation or Group is an Oxfordian geologic formation in Tajikistan and Uzbekistan and a geologic group in Turkmenistan. Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation.
WThe Kurek Formation is a late Oxfordian geologic formation of the Kugitang Svita in Turkmenistan and Uzbekistan. Fossil sauropod tracks have been reported from the formation.
WThe Madygen Formation is a Late Triassic (Carnian) geologic formation and Lagerstätte in the Batken and Osh Regions of western Kyrgyzstan, with minor outcrops in neighboring Tajikistan and Uzbekistan. The conglomerates, sandstones and mudstones of the 560 m (1,840 ft) thick formation were deposited in terrestrial lacustrine, alluvial, fluvial and deltaic environments.
