The Xiguayuan Formation is an Early Cretaceous ( Barremian) geologic formation in Hebei Province of China. Fossil ornithopod tracks have been reported from the formation. [1] It was deposited in a shallow lacustrine setting and is noted for its hyperpycnite facies. [2]
Fossil content
The formation has provided the following fossils:
- Ichnofossils
- Insects
- Bivalves
