Universidad de Zaragoza (orcid)0000-0002-2430-7424 Latest Jurassic–Early Cretaceous synrift evolution of the Torrelapaja Subbasin (Cameros Basin): implications for Northeast Iberia palaeogeography 2021 Access copy available to the general public Unrestricted The reconstruction of the latest Jurassic–Early Cretaceous evolution of the Torrelapaja Subbasin (Cameros Basin, Spain) resulted in the characterization of three synrift sequences (SS-1, SS-2 and SS-3) bounded by major unconformities. Three major NW–SE normal faults combined with smaller scale faults of variable direction (around NE–SW) controlled the sedimentation. The complex geometry of the Torrelapaja Subbasin indicates a main extension direction of NE–SW, and a secondary NW–SE extension. Sedimentation of the Tithonian–middle Berriasian SS-1 occurred in alluvial fan systems, grading upwards to carbonate palustrine-lacustrine environments. A new vertebrate site with large size sauropod bones has been found in the middle part of SS-1. The lower boundary of the uppermost Hauterivian–lower Barremian SS-2 is locally a palaeokarst, with sedimentary infill including three new fossil sites with remains of ornithopod, sauropod and theropod dinosaurs. Sedimentation of SS-2 encompasses distal alluvial terrigenous facies with local palaeosoils and palustrine-lacustrine limestones grading upwards to middle-distal alluvial facies. After a late Barremian–early Albian stratigraphic gap, sedimentation resumed in coastal flat environments represented by the mudstones with intercalated skeletal (oyster-rich) sandy limestones with carbonaceous plant remains of the SS-3. A middle–late Albian age assignment of SS-3 based on regional correlation is supported by strontium isotopic data. This unit marks the first Early Cretaceous marine incursion in the area from the northern Atlantic realm. This is a notable change of the previous palaeogeographical reconstructions which established that the first marine encroachment occurred in the early Aptian and was sourced from Tethysian domains. © 2021 Elsevier Ltd info:eu-repo/grantAgreement/ES/AEI/PID2019-108705GB-I00 info:eu-repo/grantAgreement/ES/DGA/E18-20R info:eu-repo/grantAgreement/ES/DGA/E32-20R info:eu-repo/grantAgreement/ES/MICINN/CGL2017-85038-P info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 2.432 2021 PALEONTOLOGY 12 / 54 = 0.222 2021 Q1 T1 GEOLOGY 13 / 49 = 0.265 2021 Q2 T1 0.751 2021 Paleontology 2021 Q1 4.1 2021 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Bádenas, B.
