REMARKS ON THE STRATIGRAPHY AND BIOCHRONOLOGY OF THE LATE PLEISTOCENE DEPOSIT OF INGARANO (APULIA, SOUTHERN ITALY)

New field data on the Late Pleistocene deposit of Ingarano (Foggia) allow us to hypothesise the occurrence of three faunal assemblages (Ingarano a, b, c) respectively referable to isotopic stages 4, 3 and 2 of the palaeotemperature scale. The palaeontological data match with the alternating palaeoclimatical conditions during Late Pleistocene times. &nbsp

GEOLOGICAL EVOLUTION AND BIOCHRONOLOGICAL EVIDENCES OF THE MONTE RICCIO SECTION (TARQUINIA, CENTRAL ITALY)

The geological evolution of the area of M.te Riccio for the Plio-Pleistocene time span has been pointed out. The M.te Riccio area was probably an high during Gelasian-Santernian times. The stratigraphical sequence shows the passage from a coastal marine environment during Pliocene, to a coastal environment during Early Pleistocene (testified by evidences of shorelines) to continental conditions during the upper part of Pleistocene. The analysis of the mammal bones coming from a level overlying a marine formation ("Macco" auct.) allow us to ascribe the faunal association to the late Villafranchian (Tasso F.U.) referable to the beginning of the Pleistocene. It is the first signalation of an Early Pleistocene mammal fauna in the Northern Latium.&nbsp

REVIEW AND NEW DATA OF THE FOSSIL REMAINS FROM MONTE PEGLIA (LATE EARLY PLEISTOCENE, CENTRAL ITALY)

After more than sixty years since its discovery, the fossils from Monte Peglia (late early Biharian, Umbria) are reconsidered in their entirety. The small mammals of Monte Peglia upper and lower levels had been studied in the past, whereas the remains of large mammals of Monte Peglia lower level, stored in several Institutions of central Italy, are described here for the first time. The following taxa have been described: Hystrix refossa, Homotherium latidens, Panthera cf. P. gombaszoegensis, Felis cf. F. lunensis, Canis mosbachensis, Vulpes alopecoides, Meles meles, Pannonictis cf. P. nestii, Mustela palerminea, Ursus cf. U. etruscus; Macaca sylvanus florentinus, Equus altidens, Stephanorhinus cf. S. hundsheimensis, Sus sp., Capreolus sp., Axis eurygonos, Hemitragus cf. H. orientalis, Bison degiulii. Moreover, the list of small mammals of the lower level has been updated with the addition of three new small vertebrate taxa: Rana sp., Myotis sp. (large size), cf. Miniopterus sp. The study of the remains of large mammals of the lower layer indicate the survival of a number of taxa of latest Villafranchian age. If we accept the biochronological correlation of Monte Peglia with the Colle Curti local fauna, its age should be ~1.072 Ma. In this case, it is possible to pinpoint the accumulation of the lower level to the MIS 35/33, as the small mammals confirm the presence of a mixed environment with forested and open spaces and warm temperate climate. The accumulation of the upper level, characterized by taxa typical of open spaces and steppes and a cooler climate, probably occurred during MIS 34/32

THE SECTION OF TORRE PICCHIO (TERNI, UMBRIA, CENTRAL ITALY):A VILLAFRANCHIAN SITE RICH IN VERTEBRATES, MOLLUSCS,OSTRACODS AND PLANTS

Fluvial deposits of the S. Maria di Ciciliano Formation crop out near Montecastrilli (Terni), in the southwestern branch of the Tiberino Basin.  Many specimens of plants ("mummified" woods, fruits and seeds), freshwater molluscs, ostracods, vertebrate bones and coprolites were collected at Torre Picchio. This small outcrop contains a fairly rich record of fruits and seeds, among which about 50 species were identified; the most frequent invariably belong to submerged, floating and emergent aquatic herbs, possibly because these were buried not far from their place of growth, thus representing the ancient local vegetation.  The fruits and seeds of woody plants, including several exotic elements, were transported from neighbouring areas and indicate a paleoclimate similar to the present day, though slightly wetter.  Among molluscs, three distinct assemblages were found, indicating fluvial, swampy and lacustrine environment, respectively.  They contain taxa of biochronological interest, most of them typical of Early Pleistocene deposits (late Villafranchian), but making their first appearance in the Late Pliocene (Middle Villafranchian). One species, Margarifera (Pseudunio) auricularia, represents the oldest record everywhere, since it was known, so far, only from the Middle Pleistocene upwards.  As palaeoenvironmental indicators, the ostracods complete the information given by molluscs.  Vetrebrates are represented by large and small mammals, rare birds, reptiles, amphibians and some fishes.  A great number of coprolites was collected as well.  The mammal assemblage shows affinities with the Costa S. Giacomo and Olivola F. U. (Middle and Late Villafranchian, Late Pliocene). Mimomys medasensis, an Iberoccitane element, is signaled for the first time in Italy.  From the geological point of view, the S. Maria di Ciciliano Fm. is interfingering with the marine Chiani-Tevere Fm., which is mostly Santernian in age and lies unconformably on the Middle Pliocene cycle. Only in some areas representing a structural low, the continuous transition between the lower portion of this unit and Late Pliocene deposits may be observed before the heteropic episodes.  This fact suggests some inconsistencies between chronostratigraphy and biochronology in the examined area because some taxa indicate a latest Pliocene age.  A heterochrony in the extinction of some species of plants and animals is suggested as a possible solution to the problem.&nbsp
