Geological context and micromammal fauna characterisation from the karstic infilling of La Pedrera (Albaida, Valencia, E Spain)
2020
La Pedrera is a new palaeontological site located south of the province of Valencia, between the Betic and Iberian Ranges, in a cavity filled with sediments inside a tufa formation. Roughly 260 fossil remains, corresponding to 14 taxa, have been recovered and studied from Unit III. Six rodents (Microtus sp., M. sp. gr. M. (Terricola) duodecimcostatus-lusitanicus, Microtus sp. gr. M. brecciensis-cabrerae, Arvicola sapidus, Eliomys quercinus, and Apodemus sp. gr. sylvaticusfl avicollis), one lagomorph (Oryctolagus cf. cuniculus), three insectivores (Soricinae indet., Crocidura sp., and Talpa cf. europaea) and four bats (Myotis blythii, Rhinolophus cf. ferrumequinum, Myotis bechsteinii, and Rh…
PALAEOECOLOGY AND TAPHONOMY OF THE STRAIGHT-TUSKED ELEPHANT LATE MIDDLE PLEISTOCENE SITE OF POGGETTI VECCHI (SOUTHERN TUSCANY, ITALY)
2018
Works for the construction of thermal pools at Poggetti Vecchi, near Grosseto (Tuscany, Italy) exposed an accumulation of fossil bones, largely belonging to the straight-tusked elephant Palaeoloxodon antiquus, mixed up with stone and wooden tools. The site is radiometrically dated to the late Middle Pleistocene, and the artefacts were thus created by early Neanderthals. Palaeobiological and taphonomic analyses of the fauna remains are part of a more general, multiproxy study of the site that provides new information on MIS 7-6 transition, as well as on human-animal interactions.
The small mammals (insectivores, bats and rodents) from the Holocene site of Vallone Inferno (Scillato, Sicily)
2013
The Vallone Inferno rock-shelter is an archeological site located at 770 m a.s.l. in the Madonie massif in Sicily. This massif is modeled into the Triassic and Oligocene sedimentary rocks of the Imerese Basin. Thearchaeological excavations conducted since 2008 have provided a long prehistoric and historic sequence from the Neolithic to the medieval period. From the four sedimentary complexes identified, only levels 3.4 to 3.1 from complex 3 and 4.2 from complex 4 have yielded small-mammal material. Level 4.2 is poor in remains and as yet without cultural ascription, though it has a radiocarbon age of 9450±50 years BP. Level 3.4 has yielded fragments of ceramic characteristic of the Middle N…
Environmental and depositional controls on laminated freshwater carbonates: An example from the Roman aqueduct of Patara, Turkey
2013
Carbonate deposits in aqueducts are a new high-resolution data source for environmental changes during the time of the Roman Empire, notably in the fields of palaeoclimate and spring hydrology. In order to distinguish environmental effects from those related to depositional setting, laminated carbonate deposits were compared along the entire length of an ancient aqueduct channel at Patara, Turkey. The carbonate deposits, up to 80mm in thickness, are composed of lamina couplets up to 1mm thick of alternating porous microspar and dense, columnar sparite. The former formed in the dry, warm season and the latter in the wet, cool season. The presence of biofilms seems to play a role in the devel…
Evaporite karst in Italy: A review
2017
none 16 si Although outcropping rarely in Italy, evaporite (gypsum and anhydrite) karst has been described in detail since the early 20th century. Gypsum caves are now known from almost all Italian regions, but are mainly localised along the northern border of the Apennine chain (Emilia Romagna and Marche), Calabria, and Sicily, where the major outcrops occur. Recently, important caves have also been discovered in the underground gypsum mines in Piedmont. During the late 80s and 90s several multidisciplinary studies were carried out in many gypsum areas, resulting in a comprehensive overview, promoting further research in these special karst regions. More recent and detailed studies focused…
Scripts for Quality Control of SISAL workbooks
2020
Files needed for Quality Control checks of the SISALworkbook_v12 (Comas-Bru and Harrison, 2019). This includes a Python script (wb_check_v12_compatible.py) for automatic checks and an R script (plot_agemodels_hiatus_v12) for manual checks. Instructions on how to run these scripts are provided in a README_instructions.txt file. See supplementary material of Comas-Bru et al (2020, https://doi.org/10.5194/essd-2020-39) for further information on the checks.
