Villalba de la Sierra Formation (Spain)

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.

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.

<i>Rhabdodon</i> Extinct genus of dinosaurs

Rhabdodon is a genus of ornithopod dinosaur that lived in Europe approximately 70-66 million years ago in the Late Cretaceous. It is similar in build to a very robust "hypsilophodont", though all modern phylogenetic analyses find this to be an unnatural grouping, and Rhabdodon to be a basal member of Iguanodontia. It was large amongst its relatives, measuring approximately 4–6 m (13–20 ft) in length and 250 kg (550 lb) in body mass.

<i>Ampelosaurus</i> Extinct genus of dinosaurs

Ampelosaurus is a titanosaurian sauropod dinosaur from the Late Cretaceous Period of what is now France. Its type species is A. atacis, named by Le Loeuff in 1995. A possible unnamed species has given Ampelosaurus an age reaching to the latest Cretaceous, from about 70 to 66 million years ago.
