A total of 31 vertebrate fossil sites and tracksites have been recognized within this unit in the Ladruñán area (Teruel province). Detailed stratigraphic, sedimentological and micropalaeontological analyses have also been performed in the unit. A vertical sedimentary trend from alluvial-dominated facies (meandering river and related overbank areas) to palustrine-lacustrine facies and back has been defined for the Mirambel Formation in this area. The depositional system was located close to the coastline, as indicated by sporadic marine input in the lower part of the unit. Most fossil remains were recovered by surface collection as well as by the usual techniques used for macrovertebrate excavations. The dinosaur record identified comprises ornithopods, theropods and sauropods. Four distinct track-bearing horizons have been identified. The heterolithic nature and aggradation characteristic of the Mirambel Formation are favourable factors for track formation and preservation. The dinosaur tracks consist of convex hyporeliefs or concave epireliefs that record the trackmakers as they frequented lakeshores, alluvial floodplains and fluvial courses. Macrovertebrate bonebeds occur in alluvial settings (poorly-drained floodplains and “ponds”). Microvertebrate concentrations are located in shallow lacustrine deposits. Isolated skeletal elements can be found in a great variety of deposits. Attritional accumulation in a low-energy depositional context is the general pattern of origin for the bone-bearing fossil sites of the Mirambel Formation. As regards the genetic framework, the resulting skeletal assemblages are predominantly the result of physical factors, with sedimentology as a key factor, rather than biological phenomena. Eggshell fragments are frequent throughout the unit but are clearly more common in palustrine-lacustrine deposits. These can be taken to be parautochthonous bioclasts from nearby areas and might be indicative of the preferential affinity of the egg-layers for wetlands and lakeshores. 000169106 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttps://creativecommons.org/licenses/by-nc-nd/4.0/deed.es 000169106 590__ $$a2.375$$b2017 000169106 591__ $$aPALEONTOLOGY$$b5 / 53 = 0.094$$c2017$$dQ1$$eT1 000169106 591__ $$aGEOGRAPHY, PHYSICAL$$b23 / 49 = 0.469$$c2017$$dQ2$$eT2 000169106 591__ $$aGEOSCIENCES, MULTIDISCIPLINARY$$b71 / 189 = 0.376$$c2017$$dQ2$$eT2 000169106 592__ $$a1.285$$b2017 000169106 593__ $$aEarth-Surface Processes$$c2017$$dQ1 000169106 593__ $$aPaleontology$$c2017$$dQ1 000169106 593__ $$aOceanography$$c2017$$dQ1 000169106 593__ $$aEcology, Evolution, Behavior and Systematics$$c2017$$dQ1 000169106 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000169106 700__ $$0(orcid)0000-0002-7210-1033$$aMoreno-Azanza, M. 000169106 700__ $$0(orcid)0000-0003-1112-524X$$aBádenas, B.$$uUniversidad de Zaragoza 000169106 700__ $$aDíaz-Martínez, I. 000169106 700__ $$0(orcid)0000-0003-3950-1630$$aCastanera, D. 000169106 700__ $$0(orcid)0000-0003-1732-9155$$aCanudo, J.
