The Castrillo de la Reina Formation is a geological formation in Spain. It is late Barremian to early Aptian in age. It interpreted as a fluvial deposit. It primarily consists of red clay, with ribbon shaped sandstone channel fills. The rebbachisaurid dinosaur Demandasaurus is known from the formation,^[1] alongside somphospondylan Europatitan^[2] as well as indeterminate small ornithopods, iguanodonts and spinosaurids, the earliest known stem-rhabdodontid (indeterminate)^[3] and the lizard Arcanosaurus.^[4]
