The ichnoassemblage occurs in the Galve Formation (Galve sub-basin, Maestrazgo Basin) and comprises around 40 tracks assigned to theropods and ornithopods. In this paper, we undertake a paleoenvironmental analysis of the succession, which includes the overbank deposits of a fluvial environment, and discuss the implications of these findings for trackway preservation and orientation. The track-bearing unit is composed of fine- to very fine-grained, thinly bedded sandstone layers with wave ripples and traces of the Mermia ichnofacies, which were deposited as splay deposits within an ephemeral overbank pond. Two different theropod ichnotaxa (Megalosauripus cf. transjuranicus and Grallatoridae indet.) of three different size classes occur as small-, medium-, and large-sized tracks. The ornithopod tracks are classified as cf. Iguanodontipus isp. Five theropod trackways (M. cf. transjuranicus) show a bimodal orientation pattern with a similar orientation to NE-SW wave ripple crests, suggesting that these animals were walking parallel to the shoreline of the ephemeral overbank pond. Three of them walked in a similar subparallel orientation, but there is no evidence suggesting gregarious behavior as they have slightly different orientations and/or speed values. The Los Corrales del Pelejón site is an example of environmental influence on dinosaur behavior. info:eu-repo/grantAgreement/ES/DGA-FEDER/E04-23R info:eu-repo/grantAgreement/ES/DGA/E18-23R info:eu-repo/grantAgreement/ES/MICINN/PID2021-122612OB-I00 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 2.6 2023 PALEONTOLOGY 4 / 57 = 0.07 2023 Q1 T1 GEOGRAPHY, PHYSICAL 28 / 65 = 0.431 2023 Q2 T2 GEOSCIENCES, MULTIDISCIPLINARY 97 / 254 = 0.382 2023 Q2 T2 0.994 2023 Earth-Surface Processes 2023 Q1 Paleontology 2023 Q1 Oceanography 2023 Q1 Ecology, Evolution, Behavior and Systematics 2023 Q1 5.9 2023 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Aurell, Marcos Universidad de Zaragoza (orcid)0000-0002-2430-7424 Canudo, José Ignacio Universidad de Zaragoza (orcid)0000-0003-1732-9155 Cuenca-Bescós, Gloria Universidad de Zaragoza (orcid)0000-0001-5125-9651 Gasca, José Manuel Bádenas, Beatriz Universidad de Zaragoza (orcid)0000-0003-1112-524X 2000 655 Universidad de Zaragoza Dpto.
