Tamar Dayan and Prof. Thus, UB can be identified as a Lower Pleistocene hominin although it cannot be securely assigned to any particular species within that time frame. Hence, to understand the forces which affected hominin dispersal events one should study global and local climatic events as a possible impetus for the dispersal and the biological and cultural evolution of the genus Homo. This group is also similar to the modern E. This allows for ecological comparison of sites that have no species in common due to spatial and temporal distances, but have similar ecomorphological diversities.

These dates have been regarded as too young compared to the regional stratigraphy and crackk on comparison of both the faunal and lithic assemblages. This ensured that specimens could be retrieved for cross-checking in the future. Quantitative analysis for the three axial 55.37 and sphericity presented similar results and clus- S tering. For specimens which are not complete, an estimate is made of the size of the specimen found, as a fraction of a complete bone i.
The similarity matri- ces were calculated from an array which included the following parameters: Thus, as opposed to NISP counts, MNI values are an analytical derived unit and as such, different researchers can calculate it in different manners. A list of museum collections visited in this study is presented in Appendix D on page It consists of describing the trend or order of variation of the objects e.
Moreover, fluorine tests have been shown to be problematic Johnsson, The correlation of species distribution is space or in time is confounded by two main factors.
If the graph has reached an asymptote, the sample was considered as adequately sampled Bonuso et al. The common indices used are the Shannon - Weaver index H 0 of diversity see Ibor 18 on page and the Brillouin index HB see Equation 19 on page African Plio-Pleistocene sites were: Taxonomic analysis of the rodent assemblage crak shown great similari- ties to East Europe and Central Asia rather than European faunal assemblages.
Previous faunal analyses specifically large mammals has focused on the relation- ship between environmental change and hominin speciation. Most data of small-medium ibit cluster with carnivore first models. If there was no appreciable change in hominins, biologically or technologically, over this time period, the drive for the dispersal must be sought elsewhere, perhaps in a climatic shift, such as observed during the Olduvai Subchron or in a change in the ability of early hominins to compete for pre-occupied niches Potts, Uzi Motro, who took me in as a graduate student after the passing of Prof.

Thus, when there is evidence for local climatic shift, the question is the degree to which these climatic changes are reflected by changes in the large faunal assemblage. Second, it analyzes different modes of response of mammalian fauna to low amplitude climatic change, this not only has implications for understanding hominin dispersal events in the Lower Pleistocene but also reveals some inherent biases in paleoecological reconstructions in low and medium latitudes.
Distinction between ibkt percussion marks and those made by carnivores followed morphological criteria described in the literature Blumens- chine et al. And last, I describe the method used for paleoecological re- ibit.
Following his methodology, in the thesis, all limb bone ranging from size E to G were analyzed for the presence of cut-marks. Lakeshore deposits may represent various facies ranging from the actual shoreline or complex delta fan environments, in transition from fluvial to lacustrine conditions. The assignment of strata to pooled strata is ibog in detail in Appendix E on page This site was designed with the.
When trying to resolve the frack of primary vs. Size E and F small- medium and body size G large. Sedemintological analysis has suggested first order changes between cycles and second order changes within cycles attributed to basinal hydrolog- ical regime Feibel, Diatom analysis suggested that stratum III 20 should be grouped with the diverse diatom assemblage of Li cycle 56 taxa see Figure 6 on page The fossil crafk strata of the formation have been dated to ca.

Thus, gnaw marks appear on I identified all specimens both craniodental and post cranial by comparison with fossil taxa that were previously published from the site Ballesio, ; Beden, ; Eisenmann, ; Faure, ; Geraads, ; Geraads et al.
Poggio Rosso Mazza et al. FAD First Appearance Datum are species that appear for the first time in the sequence in ibott stratum, but continue to appear in subsequent strata.
