The direct comparison between microcharcoal and pollen data from the Holocene sediment core of Lago di Pergusa (central Sicily, Italy) led us to investigate the linkages between fire, vegetation, and climate in the Mediterranean Basin. The role of human populations in shaping the environment of the last millennia was closely examined as well. Pollen and charcoal were extracted using a standard pollen...
The materials of Aeretes melanopterus from the Tianyuan Cave, a Late Pleistocene site with human fossils recovered recently near Zhoukoudian, are the richest of this species ever reported in North China. Aeretes melanopterus is an endemic species of China, its relationship with Petaurista and Trogopterus is still controversal. Studies based on the dental characters show that Aeretes melanopterus resembles...
Based on published data and review of Mecynoptera splendida Handlirsch, 1904, a wing venation ground plan applicable to most taxa of the Palaeozoic superorder Palaeodictyopteroidea is proposed, where each major vein system has a simple anterior sector, and, primitively, a dichotomously branched posterior sector. Lodetiella magnifica nov. gen. and sp. is described, based on an isolated hind wing from...
We present here an overview of the Oligocene-early Miocene transgressive cover of the Betic-Rifian Internal Zone (BRIZ). Biostratigraphic data, depositional environment and stratigraphical correlations are here inferred based upon the planktonic foraminifera. The studied transgressive cover developed in two successive groups, which were generally deposited in the same depocenters. The older group...
This study represents a contribution to the developing knowledge about the microfloristic provincialism affecting Upper Triassic palynoflora. The compositional differences existing between the Onslow and the Ipswich microfloras are mainly based on the presence, in the Onslow microflora, of a diverse and more varied group of gymnosperm pollen grains, including typical European elements. In this study,...
Small and large mammals associated in Early Pleistocene floodplain sediments outcropping near Castagnone (Cerrina Valley, northern Monferrato Hills, Piedmont, NW Italy) are here examined, with particular emphasis on the voles. The micromammal assemblage includes Talpa sp., Sciurus cf. S. warthae, Mimomys savini, Mimomys pusillus, Microtus (Allophaiomys) cf. M. (A.) nutiensis, Ungaromys cf. U. nanus,...
Terrigenous marine and continental sediments constitute pollen reservoirs able to fulfil the lack of Pleistocene data extracted from autochtonous lacustrine sediments for palaeovegetation reconstructions. Nevertheless, it is essential to constrain the signification of the pollen signal in such still under-exploited sediments. This article introduces a study carried out on the shelf of the Gulf of...
Lithofacies analysis of the upper part of the Pliocene succession of the Valdelsa basin (central Italy) unravelled a number of depositional environments, ranging from alluvial plain to coastal, to marine. Strata are arranged in a hierarchy of elementary and composite unconformity-bounded units. A palaeoecological study of macro- (molluscs) and microfossils (pollen, dinocysts, foraminifera) allowed...
