Ankylosaur remains

An isolated osteoderm of an ankylosaur from the early Barremian El Castellar Formation, Teruel province. Thyreporan dinosaurs are scarce in the Lower Cretaceous from Spain but some occurrences have been cited (e.g. Pereda-Suberbiola et al., 2007; Gasulla et al., 2011). In Teruel province thyreophorans are also present within the Wealden facies (Pereda-Suberbiola et al., 2005; Gasca et al., 2009).
