In the Iberian Peninsula the fossil record of artiodactyls spans over 53 million years. During the Pleistocene, wild cattle species such as Bison and especially Bos became common. In Late Pleistocene, the aurochs (Bos primigenius) was widespread and the only bovine living along the large river valleys of southern Iberia. Although commonly found in fossil sites and especially in cave bone assemblages, the trace fossil record of aurochs was known worldwide only from the Holocene. Large bovine and roe deer/caprine tracks were found in at least five horizons of the early Late Pleistocene (MIS 5) beach and eolian deposits of Cape Trafalgar (Cadiz Province, South of Spain). The large bovine tracks are formally described as Bovinichnus uripeda igen. et isp. nov. and compared with the record of aurochs tracks, large red deer tracks and steppe bison biogeographical distribution in Iberia. Aurochs were the most likely producers of the newly described Trafalgar Trampled Surface (TTS) and some of the large artiodactyl tracks in the Matalascañas Trampled Surface, representing the oldest aurochs track record known. This new evidence, together with comparisons with the record of possible aurochs tracks in the Mid-Late Pleistocene coastal deposits from the Asperillo cliff section in Matalascañas (Huelva Province, SW Spain) and bone assemblages known in Gibraltar, point to a recurrent use of the coastal habitat by these large artiodactyls in SW Iberia.

Tracks and trackways of newborns, calves and juveniles attributed to straight-tusked elephants were found in the MIS 5 site (Upper Pleistocene) known as the Matalascañas Trampled Surface (MTS) at Huelva, SW Spain. Evidence of a snapshot of social behaviour, especially parental care, can be determined from the concentration of elephant tracks and trackways, and especially from apparently contemporaneous converging trackways, of small juvenile and larger, presumably young adult female tracks. The size frequency of the tracks enabled us to infer body mass and age distribution of the animals that crossed the MTS. Comparisons of the MTS demographic frequency with the morphology of the fore- and hind limbs of extant and fossil proboscideans shed light into the reproductive ecology of the straight-tusked elephant, Palaeloxodon antiquus. The interdune pond habitat appeared to have been an important water and food resource for matriarchal herds of straight-tusked elephants and likely functioned as a reproductive habitat, with only the rare presence of adult and older males in the MTS. The preservation of this track record in across a paleosol surface, although heavily trampled by different animals, including Neanderthals, over a short time frame, permitted an exceptional view into short-term intraspecific trophic interactions occurring in the Last Interglacial coastal habitat. Therefore, it is hypothesized that Neanderthals visited MTS for hunting or scavenging on weakened or dead elephants, and more likely calves. [ABSTRACT FROM AUTHOR]

Valencina (Seville, Spain) is one of the most important megalithic sites of the third millennium BCE in Western Europe. Among its most celebrated monuments are the tholoi of Montelirio, La Pastora, Matarrubilla, and Structure 10.042-10.049. Although sharing the same architectural tradition, these monuments were raised at different times of Valencina's history and present important formal differences. In particular, the tholoi of La Pastora and Matarrubilla contrast with that of Montelirio in that they are devoid of artistic ornamentation such as paintings and engravings, showing instead an inordinate number of natural geological features. This study, focusing on La Pastora and Matarrubilla, offers an innovative approach to the notion of "megalithic art." Firstly, these elements are characterized and classified and their natural origin established. Thus, the calcareous sandstone blocks dated from the Tertiary reveal structures on their surfaces generated by biological (bioturbation) and physical (by currents) processes during the Neogene. The surfaces of certain slabs of identical lithology at La Pastora experienced more recent intense marine bioerosion and bioconstructions in the form of Ostrea preserved to this date. Secondly, we emphasize the choice of different rock types following a certain pattern or serving to highlight a particular constructive element. In sum, all the natural elements bear highly aesthetic qualities and appear to have been deliberately chosen to highlight specific decorative or symbolic aspects. As a result, we suggest that future research on "megalithic art" should include analogous geological examinations in order to discern the origin and nature of the different elements.
