Upper Bedoulian Formation

The Upper Bedoulian Formation is a geological formation in the Murcia Region, Spain whose strata date back to the Early Cretaceous (late Barremian to early Aptian stage). The marls were deposited in an open marine environment. The lower unit (30 metres (98 ft) thick) is marly with iron concretions and septaria.[1]

The formation was deposited in the Pre-Betic Basin in southeastern Spain. During deposition, Iberia was an island, separated by seas from North Africa and France.

The Upper Bedoulian Formation has provided very few fossils; the ammonite Dufrenoyia dufrenoyi and the coral Montlivaltia multiformis.[2]
