Nuevo hallazgo de restos de proboscídeo en depósitos fluviales afectados por procesos kársticos. Pleistoceno inferior de la Cuenca del Ebro, Zuera (Zaragoza)
A partial tusk of Elephantidae indet. was recently discovered in Early Pleistocene gravel deposits belonging to a terrace of the Gállego River, near to Zuera village. Stratigraphic studies have allowed four sedimentary units to be differentiated, named (from base to top) U1 to U4. The whole successi...

| Sumario: | A partial tusk of Elephantidae indet. was recently discovered in Early Pleistocene gravel deposits belonging to a terrace of the Gállego River, near to Zuera village. Stratigraphic studies have allowed four sedimentary units to be differentiated, named (from base to top) U1 to U4. The whole succession is 35 m thick; the tusk remains were collected at the top of unit U1. Preliminary report on the taphonomy suggests that this specimen could be a reworked fossil. Evaporite dissolution related with karst processes caused deformation structures in the overlying Quaternary deposits. Synform and tubular shapes (delimited by faults) were generated. Karstification favoured the preservation of the fossil remains |
