[2][3][4] 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.

While the lower part of the formation was deposited in an inner carbonate platform, the upward gradation into mudstone in the middle and upper portions of the formation represents a change in depositional environment to paralic and alluvial plain conditions.

[3][5] Dinosaur remains are found throughout the unit, but are more abundant and better preserved in the terrestrially deposited middle-upper sections.

Remains of the stegosaurid Dacentrurus were recovered in the Barranco Conejero locality in this formation.

[6] Over the years, other stegosaurian remains have been discovered in this formation, but none have yet been referred to a specific genus.
