Villar del Arzobispo Formation

The Villar del Arzobispo Formation is a Mesozoic geologic formation. Dinosaur remains are among the fossils that have been recovered from the formation. Remains of the stegosaurid Dacentrurus were recovered in the Barranco Conejero locality in this formation. Over the years, other stegosaurian remains have been discovered in this formation, but none have yet been referred to a specific genus.

The Villar del Arzobispo Formation's age in the area of Riodeva in Spain has been dated based on stratigraphic correlations as middle-upper Tithonian, approximately 145-141 million years old, placing it near the Jurassic-Cretaceous boundary.
