The Enciso Group is a geological formation in La Rioja, Spain whose strata date back to the Early Cretaceous.[1]

The turtle Camerochelys was described from the Enciso Group. Dinosaur remains, including the holotype of the spinosaurid Riojavenatrix, are among the fossils that have been recovered from the formation.[2] [3]

The first spinosaurid fossil remains found at Igea, Enciso Group were a jaw fragment found in 1983 and isolated teeth.
