“…The cooling was connected with an increase in seasonality, as shown by palaeoclimate analysis based on plant macrofossils. In the study area (the Pannonian domain), cooling, especially of the coldest months, was documented by Erdei et al (2007), who finds sub-zero winter temperatures. Aridity is indicated, based on leguminous elements (Erdei et al 2007).…”

Abstract:The reactions of foraminiferal and calcareous nannoplankton assemblages to global warming and cooling events in the time intervals of ca. 27 to 19 Ma and 13.5 to 15 Ma (Oligocene and Miocene) were studied in subtropical epicontinental seas influenced by local tectonic and palaeogeographic events (the Central Paratethys). Regardless of these local events, global climatic processes significantly influenced the palaeoenvironment within the marine basin. Warm intervals are characterized by a stable, humid climate and a high-nutrient regime, due primarily to increased continental input of phytodetritus and also locally due to seasonal upwelling. Coarse clastics deposited in a hyposaline environment characterize the marginal part of the basin. Aridification events causing decreased riverine input and consequent nutrient decreases, characterized cold intervals. Apparent seasonality, as well as catastrophic climatic events, induced stress conditions and the expansion of opportunistic taxa. Carbonate production and hypersaline facies characterize the marginal part of the basins. Hypersaline surface water triggered downwelling circulation and mixing of water masses. Decreased abundance or extinction of K-specialists during each cold interval accelerated their speciation in the subsequent warm interval. Local tectonic events led to discordances between local and global sea-level changes (tectonically triggered uplift or subsidence) or to local salt formation (in the rain shadows of newly-created mountains).

“…Mosbrugger et al, 2005;Erdei et al, 2007). However, our precipitation gradient shows an analogue correspondence between increased ice-sheet growth and reduced precipitation gradient, as for the Miocene major cooling (Mi3, Mi4), also for isotope events Mi6 (10.4 Ma) and Mi7 (9.45 Ma), whereas a possible correlation with Mi5 (11.7 Ma; all isotope-event ages according to Westerhold et al, 2005) is obscured because of the scarcity of available proxy-data and pure age-control (Fig.…”

It is known from present-day climates that both temporal and spatial variations in precipitation can be more pronounced than those in temperature and thus influence ecosystems and human society in more substantial way. However, very little is known about such variations in the past. Here we present an analysis of 206 palaeoprecipitation data from two twelve million year long proxy records of precipitation for Southwest (Calatayud-Teruel basin) and Central Europe (Western and Central Paratethys), spanning the late Early and Middle to Late Miocene (17.8-5.3 Ma) at a temporal resolution of about 80 kyr and 200 kyr, respectively. The estimates of precipitation are based on the ecophysiological structure of herpetological assemblages. The results show that precipitation variations in both regions have large amplitudes during the Miocene with comparable temporal trends at longer time scales. With locally 300 mm up to more than 1000 mm more rainfall per year than present, the early Langhian and the Tortonian were relatively wet periods, whereas the late Langhian and late Serravallian were relatively dry, with up to 300 to 500 mm less precipitation than present. The most humid time intervals were the early and middle Tortonian washhouse climate periods. Overall, our data suggest that the latitudinal precipitation gradient in Europe from the Middle to Late Miocene were highly variable, with a general tendency towards a reduced gradient relative to present day values. The gradient decreases during cooling periods and increases during warming periods, similar to results from simulations of future climate change. Interestingly, the precipitation gradient was reversed during the second washhouse climate period and the Early Messinian, which may have causes a negative hydrologic balance in the Eastern Paratethys during the latter time. Yet, our reconstructed gradient curve shows no direct correlation with the global temperature signal from oxygen isotopes, which implies a non-linear regional response. Our results further suggest that major fluctuations in the precipitation gradient can be responsible for shifts in ecosystem distribution, and particularly, for faunal turnover in South Western Europe.

M., Kováè, M., Hók, J., Šujan, M., Braucher, R., Rybár, S., de Leeuw, A., 2017. Late Mio cene flu vial distributary system in the north ern Dan ube Ba sin (Pannonian Ba sin Sys tem): depositional pro cesses, strati graphic ar chi tec ture and con trolling fac tors of the Piešïany Mem ber (Volkovce For ma tion). Geo log i cal Quar terly, 61 (3): 521-548, doi: 10.7306/gq.1360Aim of the study was to in ves ti gate the de tailed strati graphic ar chi tec ture of the al lu vial Volkovce For ma tion, which was de pos ited in the north ern Dan ube Ba sin dur ing the in ter val be tween 10 and 6 Ma. Two type lo cal ity ex po sures were sub ject to fa cies anal y sis and in ter pre ta tion of depositional pro cesses and >500 bore holes served for cor re la tion of spa tial vari abil ity in the char ac ter of the for ma tion. The study was fo cused on the north ern Blatné and west ern Rišòovce de pres sions, which are partly sep a rated by the Považský Inovec Moun tains horst. It was re vealed, that a mostly grav elly flu vial distributary system of the Piešïany Mem ber was de pos ited in the north ern Blatné de pres sion, partly con fined by the ex posed horst and by in cised palaeotopography. The se quence is com posed of amal gam ated braided river chan nel bod ies with no overbank strata, in re sponse to high sed i ment sup ply and low ac com mo da tion. The palaeo-stream then crossed the horst in its southern part to wards the Rišòovce de pres sion, where there was four times more ac com mo da tion. The sub merged horst acted as a bound ary, where the depositional pro cesses changed to a me an der ing river and sig nif i cant overbank de pos its started to be pre served. Only small streams were pres ent in the north ern Rišòovce de pres sion, which led to very low sed i ment sup ply com pared to the high ac com mo da tion there. The depositional sys tem was af fected mainly by the in cised palaeotopography, by the lo ca tion of sed i ment in put to gether with spa tial dif fer ences in ac com mo da tion rate caused by the ac tiv ity of the Ripòany Fault on the south east ern side of the Považský Inovec Mts.
