Intra-trackway morphological variations due to substrate consistency: the El Frontal dinosaur tracksite (lower Cretaceous, Spain). 2014 Access copy available to the general public Unrestricted An ichnological and sedimentological study of the El Frontal dinosaur tracksite (Early Cretaceous, Cameros basin, Soria, Spain) highlights the pronounced intra-trackway variation found in track morphologies of four theropod trackways. Photogrammetric 3D digital models revealed various and distinct intra-trackway morphotypes, which reflect changes in footprint parameters such as the pace length, the track length, depth, and height of displacement rims. Sedimentological analyses suggest that the original substrate was non-homogenous due to lateral changes in adjoining microfacies. Multidata analyses indicate that morphological differences in these deep and shallow tracks represent a part of a continuum of track morphologies and geometries produced by a gradient of substrate consistencies across the site. This implies that the large range of track morphologies at this site resulted from similar trackmakers crossing variable facies. The trackways at the El Frontal site present an exemplary case of how track morphology, and consequently potential ichnotaxa, can vary, even when produced by a single trackmaker. info:eu-repo/grantAgreement/ES/MINECO/CGL2011-30069-C02-01 info:eu-repo/grantAgreement/ES/MINECO/CGL2010-16447 info:eu-repo/grantAgreement/ES/MINECO/BES-2012-051847 info:eu-repo/grantAgreement/ES/MEC/AP2008-01340 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 3.234 2014 MULTIDISCIPLINARY SCIENCES 8 / 56 = 0.143 2014 Q1 T1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion (orcid)0000-0003-2024-1277 Vila, B.
