“…Clift (2010) related changes in erosion rates across Eurasia, North America and Africa with climatic fluctuations during the last 33 Ma, peaking around 16 Ma ago. In Hauptvogel and Passchier's (2012) study, the analysis of heavy mineral composition of one drill core allowed them to define the Antarctic ice dynamics related to the climatic change during the early to middle Miocene (17 to 14 Ma). Faunal studies based on the evolution of hypsodonty in large herbivorous mammals from Asia (Liu et al, 2008), and modifications on ecophysiological structure of herpetological assemblages (Böhme et al, 2010), also detected a significant increase in aridity related to the Global Cooling Event.…”

As a consequence of the growth of the Antarctic ice-sheet during the middle Miocene, a global decrease of temperatures and an associated increase in aridity provoked several environmental changes all around the world. Such environmental variations can be detected in the continental record of the mammalian prey community structure using a synecological approach. Because of the good quality of its faunas, the rich Aragonian vertebrate fossil record from the Madrid Basin (Spain) appears as a good candidate to explore these environmental changes. In order to analyse the climatic evolution of the Iberian Peninsula associated to the Global Cooling Event, two classic palaeosynecological methodologies (cenograms and body size diversity), based on body-size community structure, were applied to 6 fossil sites from the Madrid Basin, ranging over 2 million years (15.5 -13.5 Ma). To establish a comparative framework, we used the ecological faunal data from 100 modern localities uniformly distributed all around the world. Our palaeoenvironmental inference is based on multivariate discriminant analysis of the dataset containing both modern and fossil mammals. Finally, we can conclude that the Aragonian mammalian assemblage from the Madrid Basin showed a predominance of semiarid environments with pulses of higher aridity in biozones Dc, E and F associated with the Global Cooling Event of the middle Miocene.

“…Under this conditions only mechanically ultrastable minerals, such as i.e. zircon, are potentially able to survive long-term glacial transport in the sandy fraction (Hauptvogel, Passchier 2012). This study shows the highest value of the ZTR index in the easternmost part (Kątniki) and the central part (Jaźwie and Kołaczek) of the fan-like forms (Table 2, Fig.…”

This study makes an attempt to characterise Quaternary sediments in terms of their heavy minerals (HM) composition. Authors focus on the Mazovian Lowland, Central Poland, where a number of clastic sediments of different age and origin overlap. Five sedimentary settings, covering the Saalian-Holocene (MIS 1-6) time frame, have been studied to reveal whether these sediments have single or multiple source areas and to decipher sediment transformations. In the glacial setting either garnet-or amphibole-dominated sediments occur. This unequivocal mineral combination likely reflects a multi-sourcing resulting from multi-directional ice advance. The HM taken from fan-like forms and aeolian sediments are closely related; these sediments are largely multicyclic and likely derived from pre-existing recycling sediments. Similar mineral suite is also typical for long-lasting aeolian processes and is observed in dune sediments. Ultrastable components are less frequent in the coversand, which points at a shorter-lived aeolian process. Finally, the fluvial setting reveals multi-sourcing largely depending on local geological conditions.

“…Between 14.8 and 14.1 Ma the major part of the cooling occurred, associated with the increase in Antarctic deep water production and the growth of the EAIS [58]. The EAIS advanced to the coastline during this transition, and near 14.2 Ma, the Ross Sea, which was at the beginning ice free (15 Ma), contained an ice volume larger than the one found today [68]. The fast cooling resulted in a rapid shift from relative high-latitude warmth to highlatitude refrigeration [59], as supported by several proxies, like: i) biogenic silica [69]; ii) pollen records [70,71]; iii) …”

“…The Burdigalian shows an increase in the connections between Rhone basin and Eastern Paratethys, leading to hydrodynamic changes and immigration of western Mediterranean [8,9], and in the mid-latitudes was up to 6 ∘ C above the present GMT [8]. Climate was tropical and humid subtropical in the mid-latitudes [46], and the East Antarctic Ice Sheet (EAIS) was reduced in size [47]. Deep ocean water had temperatures 6 ∘ C warmer than today [48].…”

A review of the entire Neogene climate in Europe is a useful tool for climate researchers, synthesizing present day knowledge on a variety of past warmer climate modes thus facilitating the debate regarding possible future climate scenarios in the Old Continent. This work centres on the European scenario, debating possible future projections and describing the Miocene and Pliocene climate in the Old Continent. With present evidences of a global warming scenario, it is highly important that we look at past climatic events in order to better predict future climate changes impact in biodiversity. The review presented here synthesizes the literature regarding climate, faunal and floral evolution for the European Neogene, and aims to help palaeoclimatic researchers and climatologists to characterize some of the boundary conditions for modelling possible analogous of IPPC climate scenarios. If the future climate projections come to be true, it is shown that the Pliocene, and particularly the Mid Piacenzian Warm Period, should be considered as the best analogue for the impact of a warming climate in Europe.
