Castrillo de la Reina Formation
From Wikipedia, the free encyclopedia
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, the earliest known stem-rhabdodontid (indeterminate)[4] and the lizard Arcanosaurus.[5]
