Zhirkindek Formation
Geologic formation in Kazakhstan
From Wikipedia, the free encyclopedia
The Zhirkindek Formation is a Late Cretaceous geologic formation in Kazakhstan.[1] The primary lithology is sand with interbeds of clay and silt, and represents a coastal to coastal marine environment.[2] The formation has produced numerous fossils, including Lindholmemydid and Trionychid cryptodires, indeterminate remains of dinosaurs (Ankylosauridae indet., Hadrosauroidea indet., Neoceratopsia indet., Sauropoda indet., Tyrannosauroidea indet., Ornithomimidae indet., Therizinosauroidea indet and Dromaeosauridae indet) and an indeterminate species of pterosaur Azhdarcho.[3]
