During the last century, Grotta Romanelli (Southern Italy) has been a reference site for the European Late Pleistocene stratigraphy, due to its geomorphological setting and archaeological and palaeontological content. The beginning of the sedimentation inside the cave was attributed to the Last Interglacial (MISs 5e) and the oldest unearthed evidence of human occupation, including remains of hearths, was therefore referred to the Middle Palaeolithic. Recent surveys and excavations produced new U/Th dates, palaeoenvironmental interpretation and a litho-, morpho- and chrono-stratigraphical reassessment, placing the oldest human frequentation of the cave between MIS 9 and MIS 7, therefore embracing Glacial and Interglacial cycles. These new data provide evidence that the sea reached the cave during the Middle Pleistocene and human occupation occurred long before MISs 5e and persisted beyond the Pleistocene- Holocene boundary., (© 2022.

In the last decades, many studies have focused on the description of fossil badger materials from Eurasia and several evolutionary hypotheses have been proposed. Nevertheless, the debate on taxonomy of the Late Villafranchian-Aurelian European badgers is still far from being solved and several species/subspecies were established over time. Herein, we described for the first time the craniodental and postcranial remains of Meles meles from Grotta Laceduzza (Apulia, Southern Italy), representing the largest sample of this taxon in the European Pleistocene record. Morphological and morphometric comparisons with fossils coming from the European Pleistocene sites were carried out; morphometric data were also compared with those of several extant populations of the European badger. The results of this work suggest that the badger fossil remains from the Mediterranean region can be considered as an ecomorphotype of this highly polymorphic species, showing a great morphological and morphometric variability throughout its wide geographical range. This variability is mainly expressed in some craniodental features and body size and could reflect local ecological adaptations, also linked to glacial/interglacial cycles.

Grotta Polesini is one of the most famous paleontological and archaeological sites of central Italy, which testifies to its human occupation during the Lateglacial. The site comprises a cave system where systematic excavation campaigns have been carried out since the 1950s. In 1974, 656 mammal remains were collected but never studied. This fossil collection is here described for the first time through taxonomic and stable isotope analyses of the enamel of selected mammal teeth. The aim is to reconstruct the paleoenvironmental and climatic conditions of the site and to offer new information on terrestrial ecosystems during the Lateglacial in central Italy. The faunal assemblage studied herein, in addition to other species reported in previous works, suggests cold climate conditions. We also describe a right radius of an adult individual of Homo sapiens, increasing the human fossil record of the site. Carbon isotope data point to a scenario dominated by C3 plants in open and dry habitats, such as grasslands and steppes, in accordance with the pollen data from central Italy. The oxygen isotope data suggest the use of water resources with a local origin, i.e. local precipitation and surface waters with a provenance from the nearby Apennine chain. The ecology of the taxa influenced the oxygen isotope values, especially in the case of semi‐obligate to non‐obligate drinker species. [ABSTRACT FROM AUTHOR]

Our work presents an updated overview of the Italian Middle Pleistocene records of hippopotamuses, including the two species Hippopotamus antiquus and Hippopotamus amphibius. In addition to reviewing several well-known fossils in the literature, a large number of samples are described herein for the first time. Following the recent results published in the literature, where the skull from the Middle Pleistocene of Cava Montanari (ca. MIS 13) was confirmed to belong to H. amphibius, one of the aims of this work was to investigate the H. antiquus–H. amphibius transition. A morphological analysis applied to a large sample confirmed the validity of the arrangement of the enamel ridges of the external surfaces of the lower canines as a diagnostic character for specific identifications. Finally, biometric analyses allowed us to test the size variability during the Middle Pleistocene, which confirmed that H. antiquus was generally larger than H. amphibius. Nevertheless, the remains of H. antiquus dated to ca. 600 ka show a reduced size when compared to older fossils of the same taxon, probably as a response to severe glacial conditions that occurred during MIS 16.

A skull of Hippopotamus recovered from the area of Tor di Quinto, within the urban area of Rome (central Italy) is here redescribed. Despite being one of the most complete specimens of hippopotamuses of the European Pleistocene, the Tor di Quinto skull did not attract much research interest, due to long-standing uncertainties on its provenance. This work begun in 2021, when the skull was restored, within a large renovation project on the vertebrate exposed at the Earth Science University Museum of Sapienza University of Rome. Original sediments were found inside the cranial and mandible cavities during the restoration work, which were sampled for petrographic analyses. By combining a review of the old paleontological, archeological and geological literature published during the 19th and 20th century on the Rome basin and the correlation of these new sedimentological and petrographic information with the lithostratigraphic and synthemic units of the national geological cartography, we clarify that the Hippopotamus skull was most likely to have been collected from a quarry called Cava Montanari, from a formation dated between 560 and 460 ka. Morphological and biometric analyses clearly support an attribution of the Cava Montanari specimen to the extant species Hippopotamus amphibius. The reassessment of the stratigraphic and geological data on Cava Montanari implies that the studied specimen is the earliest confirmed occurrence of Hippopotamus amphibius in the European fossil record.

An updated description and revision of a left hemimandible assigned to Hyaenictitherium namaquensis, a dog-like hyaena from the late Miocene locality of As Sahabi (Libya, North Africa), is here provided. This fossil is part of the historical collection discovered by Carlo Petrocchi, the Italian researcher who excavated the site in the 1930s. The As Sahabi Hyaenictitherium represents the northernmost occurrence of H. namaquensis in Africa and one of the most informative evidence of this species known to date. The hemimandible has been digitised using photogrammetric techniques, morphological and biometric analyses have been carried out taking into account the African record of Hyaenictitherium.

The extant wild boar Sus scrofa has one of the largest geographical range of all mammals, and from its appearance in the late Early Pleistocene (Epivillafranchian) it is also widely represented in the European fossil record. Early forms of the species were larger than Late Pleistocene ones, but neither the chronology nor the causes of the size reduction have been thoroughly investigated. Here, we considered for the first time a large number of fossils from several late Middle Pleistocene to Early Holocene sites of the Apulian region (Italian Peninsula). In contrast to the supposed existence of a progressive trend towards small dimensions, morphometric comparisons and body mass estimates allow us to recognize several size oscillations during the late Middle Pleistocene-Early Holocene, with large forms occurring during interglacial stages and smaller ones during glacial stages. This suggests that fossil Apulian wild boar did not conform to Bergmann's rule, that predicts larger size in colder climates due to the selective pressure towards lower surface area to volume ratio. Climate recrudescence may have played an indirect role in reducing the availability of trophic resources and hence promoting the observed pattern. [ABSTRACT FROM AUTHOR]

The giant, short-faced hyena Pachycrocuta brevirostris was the largest Hyaenidae ever existed and the one that perfectly embodied the distinctive bone-cracking adaptations of this mammal family. Its dispersal into Europe is regarded as a biochronological marker of the Late Villafranchian at ∼2.0 Ma, and its potential ecological interactions with other carnivorans and early Homo populations diffusing Out of Africa have given rise to extensive discussions. Nevertheless, our comprehension of the extinction of P. brevirostris remains vague. Here, we first critically evaluate the European fossil record of the species and then we review the whole Epivillafranchian and Galerian Hyaenidae record, including P. brevirostris , Crocuta crocuta and " Hyaena " prisca. Biometric comparisons with other extinct and extant bone-cracking hyenas are carried out. In contrast to a common view, we recognize that there is neither evidence of a persistence of P. brevirostris beyond the Early-Middle Pleistocene boundary, nor of a coexistence between the giant hyena and C. crocuta. The replacement between the two species, which was also accompanied by the arrival of " H." prisca , occurred at ∼0.8 Ma and can serve as a marker of the Epivillafranchian–Galerian turnover, part of the faunal renewal that reflects the response of mammal communities to the Early–Middle Pleistocene Transition. Moreover, we clarified that Pliocrocuta perrieri and " H. " prisca were different species, and that the latter was relatively more widespread than often assumed, being recorded from localities spanning in age almost the whole Middle Pleistocene and even the early Late Pleistocene. • The Epivillafranchian and Galerian European record of hyenas is reviewed. • Pachycrocuta brevirostris did not persist beyond the Early-Middle Pleistocene boundary, nor it coexisted with Crocuta crocuta • The Pachycrocuta - Crocuta replacement occurred ∼0.8 Ma, accompanied by the arrival of " Hyaena " prisca. • Pliocrocuta perrieri and " Hyaena " prisca were different species. • " Hyaena " prisca was documented throughout the Middle to early Late Pleistocene.

The pardel lynx Lynx pardinus is today restricted to small populations living in southern Iberian Peninsula. However, this endangered species was widely spread throughout Iberia until historical times and is currently the subject of intense conservation programs. Paleontological data suggest that its past geographical range was much wider, including also southern France and northern Italy. Here, we report exceptionally preserved fossil remains of L. pardinus from the Late Pleistocene (about 40′000 years) of Ingarano (Italy), which represent the largest sample of fossil lynx currently known in Europe. This new evidence allows (1) to revise the taxonomy of European fossil lynxes, (2) to extend far southeast the paleobiogeographical distribution of L. pardinus , and (3) to offer new insights on the evolutionary history (e.g., relationships with other extinct and extant lynx species) and paleobiology (e.g., intraspecific variation, body mass) of this iconic European felid. • We describe and analyze the Lynx sample from the Ingarano site (southern Italy). • It is the largest and best preserved European sample of Late Pleistocene lynxes. • The sample is referred to Lynx pardinus Temminck (1827). • The new data allow to revise the taxonomy of European fossil lynxes. • Compared to the extant form, the fossil L. pardinus was larger with a wider paleobiogeographical distribution.

The late Villafranchian is one of the pivotal timespans in the succession of Pleistocene European faunal assemblages, setting the bases for the major faunal renewal that characterized the continent during the Epivillafranchian. Bison is one of the most important and successful large mammals to spread in Europe at the latest stages of the Early Pleistocene. Here we describe the remains of a large bovid from the late Villafranchian site of Pietrafitta (ca. 1.5 Ma), previously attributed to Leptobos. Our analyses allow to refer this sample to the genus Bison. The primitive characters featured by this sample suggest the attribution to the subgenus Eobison , a long-debated taxon which includes all the earliest forms of Bison. At Pietrafitta, thus, one of the largest and most complete record of primitive Bison is recorded. The vague diagnosis and confused taxonomic history of Eobison called for a reappraisal of its status. We present a re-definition of the diagnostic characters and a review of the Eurasian record of Eobison with a focus on the late Villafranchian samples from the Mediterranean area. We recognize at least three valid species of Eobison remarking, however, the extreme morphological variability of this group. The comparative analysis of Eobison and its closest relatives (i.e., Leptobos and Bison s.s.), confirms that both the leptobovine and bisontine clades underwent to an increase of stoutness of the appendicular skeleton in response to the shrinking of forested habitats and the onset of colder, arid climate during the Pleistocene. • We describe the remains of a primitive form of Bison from Pietrafitta (Italy, 1.5 Ma). • We reappraise the status and fossil record of the debated subgenus B. (Eobison). • At least three valid species of Eobison are here recognized. • The diagnostic characters of Leptobos , B. (Eobison) and B. (Bison) are re-defined. • Body size and proportions of these taxa are correlated with environmental changes. [ABSTRACT FROM AUTHOR]
