Full-text available
Paleoenvironmental reconstruction of the Mediterranean Basin at the end of the Messinian Salinity Crisis is contentious. One section that records this final phase (Stage 3) is the Pollenzo Section in the Piedmont Basin (NW Italy). Here, we present new stratigraphic, sedimentological, petrographic, micropaleontological (ostracods, calcareous nannofo...
Article
Landlocked basins like the Caspian Sea are highly sensitive to changes in their hydrological budget, especially at times of disconnection from the global ocean. Here, we reconstruct the Pliocene to Pleistocene palaeohydrological and palaeoenvironmental changes occurring in the South Caspian Basin between ~3.6 and ~ 1.9 Ma, using compound-specific h...
Article
Biodiversity and conservation assessments rise and fall with taxonomic accuracy. An example of a still largely unresolved taxonomy is found in the Gastropoda of the Caspian Sea. The present paper clarifies the taxonomy of the genus Abeskunus and its three species of anomalohaline gastropods endemic to the Caspian Sea. Based on material from Pleisto...

The upper Miocene – lower Pliocene sedimentary succession of the Denizli Basin (SW Anatolia) displays a unique record of undisturbed stratigraphy and provides an excellent opportunity to study long-term palaeoecological changes. This paper documents the ostracod assemblages of two sections of the Neogene Kolankaya Formation, resulting in the follow...
Article
The Dardanelles region has formed a key gateway connecting the Eastern Paratethys and the Aegean/Mediterranean since the late Miocene. Its sedimentary sequences contain crucial information about connectivity and tectonics but so far lack unambiguous age constraints. Only a few Miocene marine episodes have been documented and fossil assemblages are...
Article
Full-text available
The Northern Aegean region evolved during the Miocene as a restricted land-locked basin with small ephemeral connections to both the Eastern Paratethys (former Black Sea) and Mediterranean. Its biostratigraphic data show mixed Paratethys-Mediterranean components, but the Paratethys fauna has generally been neglected for chronologic reconstructions....
Article
Full-text available
The timing and mechanisms of the Cretaceous sea incursions into Central Asia are still poorly constrained. We provide a new chronostratigraphic framework based on biostratigraphy and magnetostratigraphy together with detailed paleoenvironmental analyses of Cretaceous records of the proto‐Paratethys Sea fluctuations in the Tajik and Tarim basins. Th...

Homo erectus paleoenvironments in the early Pleistocene Denizli Basin: an integrated paleontological, sedimentological and geochemical approach
Article
We describe a late Miocene to early Pliocene axial drainage system in the East Carpathian foreland, which was an important sediment supplier to the Black Sea and the Dacian Basin. Its existence explains the striking progradation of the northwest Black Sea shelf prior to the onset of sediment supply from the continental-scale Danube River in the lat...
Article
Full-text available
In the late Miocene, a large inland sea known as the Eastern Paratethys stretched out across the present-day Black Sea – Caspian Sea region. The basin was mostly endorheic and its water budget thus strongly dependent on regional climate. The basin was therefore prone to high-amplitude water-level fluctuations and associated turnovers in water chemi...
Article
During the so-called Messinian Salinity Crisis (MSC: 5.97-5.33 Myr ago), reduced exchange with the Atlantic Ocean caused the Mediterranean to develop into a “saline giant” wherein ∼1 million km³ of evaporites (gypsum and halite) were deposited. Despite decades of research it is still poorly understood exactly how and where in the water column these...
Article
The early Pleistocene travertines from the Denizli Basin in SW Anatolia, from which the only known Homo erectus finding from Turkey was recovered, are unconformably overlain by a 20 m thick succession of alkaline lake deposits that bear a rich ostracod fauna. The ostracod assemblage consists of a mixture of freshwater and mesohaline tolerant taxa....
Article
The sedimentary record of the Caspian Basin is an exceptional archive for the palaeoenvironmental, palaeoclimatic and biodiversity changes of continental Eurasia. During the Pliocene–Pleistocene, the Caspian Basin was mostly isolated but experienced large lake level fluctuations and short episodes of connection with the open ocean as well as the Bl...

The Pontocaspian (Black Sea - Caspian Sea) region has a very dynamic history of basin development and biotic evolution. The region is the remnant of a once vast Paratethys Sea. It contains some of the best Eurasian geological records of tectonic, climatic and paleoenvironmental change. The Pliocene-Quaternary co-evolution of the Black Sea-Caspian S...
Article
Investigation of a > 6 km thick succession of Cretaceous to Cenozoic sedimentary rocks in the Tajik Basin reveals that this depocenter consists of three stacked basin systems that are interpreted to reflect different mechanisms of subsidence associated with tectonics in the Pamir Mountains: a Lower to mid‐Cretaceous succession, an Upper Cretaceous‐...
Article
Full-text available
Palaeoecological records are required to test ecological hypotheses necessary for conservation strategies as short-term observations can insufficiently capture natural variability and identify drivers of biotic change. Here, we demonstrate the importance of an integrated conservation palaeobiology approach when making validated decisions for conser...
Article
The proto‐Paratethys Sea covered a vast area extending from the Mediterranean Tethys to the Tarim Basin in western China during Cretaceous and early Paleogene. Climate modelling and proxy studies suggest that Asian aridification has been governed by westerly moisture modulated by fluctuations of the proto‐Paratethys Sea. Transgressive and regressiv...
Article
The semi-isolated epicontinental Paratethys Sea in the Eurasian continental interior was highly sensitive to changes in basin connectivity and hydrological budget. The Caspian Sea, the easternmost basin experienced a five-fold increase in surface area during the Plio-Pleistocene climate transition, but a basic process-based understanding is severel...
Article
During the Cenozoic, the constant northward movement of the African plate led to the division of the Tethys Ocean into two: the Palaeomediterranean and the Paratethyan branches. The latter was represented by a huge epicontinental sea and brackish to freshwater lakes that extended across central Europe and western Asia. Neogene and Quaternary ostrac...

ABSTRACT New palynological, ostracod and foraminiferal data are presented from a long outcrop section in the Jeirankechmez river valley, Azerbaijan, near the western coast of the Caspian Sea. The interval studied includes the upper part of the Pliocene Productive Series and overlying Plio-Pleistocene Akchagylian (Akchagyl) and Apsheronian (Apsheron...
Article
Full-text available
Central Eurasia underwent significant paleoclimatic and paleogeographic transformations during the middle to late Miocene. The open marine ecosystems of the Langhian and Serravallian seas progressively collapsed and were replaced in the Tortonian by large endorheic lakes. These lakes experienced major fluctuations in water level, directly reflectin...
Article
Widespread evaporites were deposited in large parts of the Central Paratethys during the so-called Badenian Salinity Crisis (BSC). The adverse environmental conditions that accompanied the BSC triggered a demise in the basin’s marine fauna, inducing the socalled middle-Badenian-extinction-event. While tectonic activity preconditioned the Central Pa...

The Razim–Sinoie lagoon (Fig. 1) is a dynamic coastal lake system that is considered prime habitat of the unique Pontocaspian species. This fauna has adapted to changes in salinity over time but is now under threat. The lake’s salinity depends on relative influx of freshwater from the Danube Delta in the north and influx of mesohaline Black Sea wat...

Sedimentological facies models for (semi-)isolated basins are less well developed than those for marine environments, but are critical for our understanding of both present-day and ancient deltaic sediment records in restricted depositional environments. This study considers an 835 m thick sedimentary succession of mid-Pliocene age, which accumulat...
Article
The First Occurrence of the cysts of the dinoflagellate Galeacysta etrusca is a well-known marker for the final stage of the Messinian Salinity Crisis in the Mediterranean Basin. This taxon originated from the Paratethys in the north and migrated in a stepwise fashion towards the Mediterranean. Using the First Occurrence of this species throughout...
Article
Middle Jurassic and Early Cretaceous rocks from Romania have yielded two new genera and three new species of decapod crustaceans, Romaniacheiros lophia n. gen., n. sp., Paraclythia cernavoda n. sp., and Daciapagurus minusculus n. gen. n. sp. New occurrences for Erymidae and Axiidae are also reported.

Fossil decapod crustaceans are reported from eight Late Jurassic localities in Dobrogea, southeastern Romania. Six species are present in this collection, two of which are new, Longodromites akainokkos, and Planoprosopon conspicuus. In this study, localities dominated by sponge bioherms are markedly less diverse than those dominated by coral reefs....
Article
The Black Sea and Caspian Sea are the present-day remnants of a much larger epicontinental sea on the Eurasian continental interior, the Paratethys. During the late Miocene Messinian Salinity Crisis (MSC), a unique oceanographic event where 10% of the salt in the world's ocean got deposited in the deep desiccated basins of the Mediterranean, the Pa...
Article
Deposits of the Balta Fm are preserved in a large arcuate sediment body that covers about 60000 km² and is up to 350 m thick. The Balta Fm spans ca. 5 Ma as constrained by underlying Tortonian (Bessarabian) and overlying Messinian (early Pontian) Paratethys strata. It contains frequent terrestrial mammal fossils and fresh- as well as brackish-water...
Conference Paper
The Kocabaş travertines that host the earliest Homo erectus from Anatolia (Turkey) are laterally interfngering with a succession of lake and playa type of deposits which shed light on the palaeoenvironmental conditions in which Denizli man lived. We studied the sedimentary succession encompassed from 1.2 to 1.6 Ma based on cosmogenic nucleids (2...
Article
A gigantic cascade of Atlantic waters, filling the deep desiccated Mediterranean basin at the beginning of the Pliocene, has commonly been envisaged to end the Messinian Salinity Crisis (MSC). The Mediterranean lowstand during its final "Lago-Mare" phase, however, has long been subject to major controversy and has recently been seriously questioned...
Article
Full-text available
Climatic changes cause large paleoenvironmental responses in semi-isolated basins. We analyze here the sedimentary successions of the Dacian Basin (Romania) to evaluate Late Pliocene and Early Pleistocene paleoenvironmental changes through macro- and micropaleontology. These changes are dated by creating a magnetostratigraphic time frame for two lo...
Article
Plate tectonics and eustatic sea-level changes have fundamental effects on paleoenvironmental conditions and bio-ecological changes. The Paratethys Sea was a large marine seaway that connected the Mediterranean Neotethys Ocean with Central Asia during early Cenozoic time. Withdrawal of the Paratethys from central Asia impacted the distribution and...
Article
A vast shallow epicontinental sea extended across Eurasia and was well-connected to the Western Tethys before it retreated westward and became isolated as the Paratethys Sea. However, the palaeogeography and the timing of this westward retreat are too poorly constrained to determine potential wider environmental impacts, let alone understanding und...

The late Miocene Messinian Salinity Crisis (MSC) was an extraordinary geologic event in the Mediterranean Basin marked by massive salt accumulation and presumably basin desiccation as a consequence of the reduced water exchange with the Atlantic Ocean. The discovery of a desiccation deposit in the Black Sea, the so-called Pebbly Breccia unit, was u...
Article
Relative ages of late Cenozoic stratigraphy throughout the Caspian region are referenced to regional stages that are defined by changes in microfauna and associated extreme (>1000 meter) variations in Caspian base level. However, the absolute ages of these stage boundaries may be significantly diachronous because many are based on the first occurre...

A newly proposed biostratigraphic zonation of Early Cretaceous microfossils (mainly foraminifera) improved the resolution for dating the shelf carbonate platform deposits from Cernavodă-lock section, South Dobrogea, eastern part of the Moesian Platform. The zonation comprises 12 zones (biozones) for the Upper Berriasian-Valanginian-Lower Hauterivia...
Article
The Tarim Basin in western China formed the easternmost margin of a shallow epicontinental sea that extended across Eurasia and was well-connected to the western Tethys during the Paleogene. Climate modeling studies suggest that the westward retreat of this sea from Central Asia may have been as important as the Tibetan Plateau uplift in forcing ar...
Article
[1] The Greater Caucasus are the northernmost extent of the Arabia-Eurasia collision and are thought to represent the main locus of shortening within the central portion of the collision zone between 40° and 48°E. Recent work suggests that in detail, since the Plio-Pleistocene, much of the shortening in the eastern portion of the Caucasus system ha...
Article
In this paper we establish when and how the Pannonian basin and associated Central Paratethys basins were isolated from the remainder of the Paratethys, a system of back-arc basins and inland seas that once extended over a large part of Europe. The isolation, which occurred at the beginning of the Late Miocene, is marked by a paleoenvironmental cha...
Article
Recently, the boundary between the Late Miocene Meotian and Pontian regional stages of the Eastern Paratethys has been magnetostratigraphically dated at ~6.04 Ma. The boundary coincides with a rise in Paratethys sea-level caused by the establishment of a connection to marine waters. Following this, the Lower Pontian of the Eastern Paratethys is cha...
