Castrillo de la Reina Formation

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 occurs in the formation,^[1] alongside somphospondylan Europatitan^[2] as well as indeterminate small ornithopods, iguanodonts (including members of the Hadrosauriformes^[3]) and spinosaurids, an early rhabdodontoid (indeterminate)^[4] and the lizard Arcanosaurus.^[5]
