“…These Barremian faunas are composed of brachiosaurids and rebbachisaurids (among the sauropods), ceratosaurs, baryonychine spinosaurids, carcharodontosaurids, ornithomimosaurs, other small coelurosaurs (among the non-avian theropods), and ankylosaurs (among the thyreophorans), apart from small and large ornithopods (Pereda-Suberbiola et al, 2012;Alcalá et al, (Charig & Milner, 1997;Ortega et al, 2010;Cuesta et al, 2019), strikingly diff erent to the condition observed in MOR1 and MOR2. Finally, thyreophorans such as the Barremian ankylosaur Polacanthus, whose remains have been identifi ed in the Iberian Peninsula (e.g., Gasulla et al, 2011), have very different wider-than-high dorsal vertebrae which are excavated dorsally forming a V-shape pit, anterior caudals with hearth-shaped articular faces, and middle caudal vertebrae with rounded articular faces and transverse processes (Hulke, 1881;Pereda-Suberbiola, 1994), unlike MOR1 and MOR2. As mentioned above, the group of dinosaurs with which MOR1 and MOR2 share further characters are the ornithopods.…”
