000097960 520__ $$aThis work consists of a detailed sedimentological-paleontological study of a stratigraphic section of the lower Barremian El Castellar Formation located in Galve (Teruel province), which includes the Escarpe-Pelejón fossil site. It consists on a 30 m thick series of palustrine-lacustrine limestones, lutites and marls with abundant fossil content. <br />The detailed field and laboratory work, has allowed differentiating 12 facies based on lithology, sedimentary structures and fossil remains, which characterize 3 main depositional environments. The lower part of the unit is dominated by lutites, marly lutites and discrete sandstone beds, whose deposition took place in an alluvial-palustrine transition subenvironment with fluvial influence. In this context, a fossil-bearing bed with a great paleodiversity has been found, whose origin is given by the superposition of subenvironments due to lake dynamics during a lake expansion event. This fossil site named Escarpe-Pelejón, bear remains of organisms (vertebrates, charophytes, ostracods, mollusks…) with different lifestyles (aquatic, land and amphibious). Those remains are broken, disarticulated and dispersed, and some of them, look like allochthonous. The middle and upper part of the unit is formed by marls and marly limestones, with different proportions of charophytes, ostracods and mollusks and traces suggesting aerial exposure (nodules, root traces). These facies formed in a plaustrine subenvironment with energy flood events. Finally, the bioclastic limestones (with charophytes, ostracods, mollusks, fishes remains…) mostly bioturbated were deposited in a shallow lacustrine subenvironment with variations in energy and periods of subaerial exposure. <br />Overall, the studied unit reflects the evolution from an alluvial environment with small ponds to a shallow lake environment. The highest paleodiversity is found in lutites-marly lutites facies in the alluvial-palustrine transition subenvironment.<br /><br />
