Villar del Arzobispo Formation

The Villar del Arzobispo Formation is a Late Jurassic to possibly Early Cretaceous geologic formation in eastern Spain. It is equivalent in age to the Lourinhã Formation of Portugal. It was originally thought to date from the Late Tithonian-Middle Berriasian, but more recent work suggests a Kimmeridigan-Late Tithonian, possibly dating to the Early Berriasian in some areas. 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. In the area of Galve, the formation potentially dates into the earliest Cretaceous.[2]

Most of the unit consists of siliciclastic mudstone, however the lower portion of the formation is dominated by bioclastic, oolitic and peloidal limestone, while channelized sandstone and conglomerate is found in the middle portion of the unit. 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]

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.[4] Over the years, other stegosaurian remains have been discovered in this formation, but none have yet been referred to a specific genus.[5] Turiasaurs and brachiosaurids are also known from the formation. The formation is also well known for its fossil footprints, representing many different taxa.
