Caracterización de los depósitos sedimentarios con dinosaurios de Riodeva (Teruel)

| Sumario: | Recent discoveries of dinosaur fossils in Riodeva led us to carry out a systematic study of the geology of the area. The calcareous-siliciclastic facies rich in fossil bones are attributed to the Villar del Arzobispo Formation (Tithonian-Berriasian). These transitional facies have been divided into three different units; A) Marine-influenced siliceous-calcareous deposits, spanning 50 m., conformable over the underlying calcareous Jurassic marine unit, B) A 170 m detritical alluvial unit, including more than 35 recorded dinosaur sites (Royo-Torres y Cobos, 2004), and C) A 15-0 m detritical-calcareous unit unconformable below the erosive overlying formation (Arenas y Arcillas del Collado Formation). We also suggest a chronological explanation for taxonomical divergences between dinosaur sites previously attributed to Arenas y Arcillas del Collado formation |
