New paleontological and paleoenvironmental data on the Lower Cretaceous Oliete Sub-basin (Teruel province, Spain)


New data on palaeoenvironments and vertebrate fossil assemblages from the Oliete sub-basin have been published during 2018. A review of the onset of the synrift sedimentation and synsedimentary extensional tectonics of the Oliete sub-basin (northwestern Maestrazgo basin, East Spain) was presented by Aurell et al. (2018) based on new data acquired after extensive sedimentological, structural and palaeontological analysis of the Barremian Blesa Fm.

Furthermore, Alonso et al. (2018) presented first insights into the theropod fauna from Barranco del Hocino-1, a fossil site which is located geologically within the Oliete sub-basin, in the Blesa Formation. The tooth morphotypes studied by Alonso et al. (2018) belong to separate tetanuran theropod taxa. One is related to Spinosauridae. The other morphotypes show affinities with non-spinosaurid tetanurans, probably related to Carcharodontosauria.
