RT Journal Article T1 José Royo y Gómez y los dinosaurios españoles A1 Sanz, J. L. AB José Royo y Gómez (1895 - 1961) was the first Spanish paleontologist that realized the potential significance of the Spanish dinosaur record. His research in dinosaurs lasted from 1918 to 1927. A lot of dinosaur material was housed in the Museo Nacional de Ciencias Naturales (Madrid), most of it lost during the civil war. The main goal of Royo y Gómez was the research on wealden dinosaurs from the provinces of Castellón, Valencia y Teruel. He reported the presence of Cetiosaurus, which is very improbable under the present-day knowledge. The presence of a form akin to Megalosaurus is probable. The ornithopod Iguanodon atherfieldensis actually belongs to the Lower Cretaceous Spanish dinosaur fauna.Royo y Gómez was not convinced of the similarity of the Lower Cretaceous dinosaur fauna between the Iberian peninsula and other western Europe sites, an idea currently accepted PB Sociedad Geológica de España YR 1995 FD 1995 LK http://hdl.handle.net/10272/13402 UL http://hdl.handle.net/10272/13402 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 14 jul 2026
