The Villalba de la Sierra Formation is a Campanian to Maastrichtian geologic formation in Spain. Fossil dinosaur eggs have been reported from the formation, that comprises gypsiferous, grey, argillaceous mudstones and sandstones, deposited in a floodplain environment[1][2] characterised by high seasonality and variability in water availability.[3]

Fossil content

The formation has provided abundant titanosaurian remains, including Lohuecotitan were found in the formation.[4] More than 10,000 fossil remains of various fishes, amphibians, lizards, dinosaurs (Ampelosaurus sp., Rhabdodon sp.), turtles (Foxemys mechinorum, Iberoccitanemys convenarum), and crocodiles (Lohuecosuchus megadontos, Agaresuchus fontisensis, Musturzabalsuchus sp.) are also known from the site, one of the richest for the Late Cretaceous in Europe.[4][5]
