Introduction
I am a palynologist and my main research interests are Mesozoic-Cenozoic palaeocliamte and palaeoenvironmental renconstruction based on palynology, organic/inorganic geochemistry. I have been working on Triassic vegetation and climate changes. My recent projects have been the "Palynology of the Carnian Pluvial Episode" (still in progress) and the palynology of the Chinle Formation (USA).

Article
Fossil plant assemblages including spores and pollen grains provide useful information on past ecosystems and the response of terrestrial biotas to various environmental perturbations. New quantitative palynological data from the Chinle Formation of the American Southwest suggest that a floral turnover occurred in the middle Norian (between 217 and...
Article
Premise of research. Froelichsporites traversei is a prominent palynomorph in the Upper Triassic of North America that always occurs in tetrahedral permanent tetrads. It is an important regional biostratigraphic marker in the Norian of North America, and its abundance rises around 215 Ma, associated with a significant floral and faunal turnover. It...
Article

The geological record contains evidence for numerous pronounced perturbations in the global carbon cycle, some of which are associated with mass extinction. In the Carnian (Late Triassic), evidence from sedimentology and fossil pollen points to a significant change in climate, resulting in biotic turnover, during a time termed the ‘Carnian Pluvial...
Article
The Danube Basin is situated between the Eastern Alps, Western Carpathians and Transdanubian mountain ranges and represents a classic petroleum prospection site. The basin fill is known from many 2D reflection seismic lines and deep wells with measured e-logs which provided a good opportunity for theories about its evolution. New analyses of deep w...
Article
The marine system of the Mediterranean-Paratethys region in the Middle Miocene was influenced by the global climatic changes corresponding to the Miocene Climate Optimum. The latter was characterized by global warming of deep oceanic waters succeeded by a decrease of wind activity and ocean water circulation together with a decline in oceanic produ...
Article
The biota of the brackish-water Lake Pannon in the Pannonian Basin is characterized by remarkable endemism due to the isolated evolution of the lake for 8 myr after the last Miocene marine connection ceased (∼11.6 Ma). A conspicuous feature of this endemism is the large, probably ecophenotypic variation in the morphology of brackish-water dinoflage...
Article
The Yanchang Formation was deposited during the Middle Triassic in a vast lacustrine basin in the modern Ordos Basin and is a main target for hydrocarbon exploration in Central China. It is divided, based on sedimentary cycles and lithology, into the Chang 10 (the oldest) to Chang 1 (the youngest) members. During the deposition of the Chang 7 Membe...
Article
New palynological data from the deep-water Gusterita section in the Transylvanian Basin depicts the late Miocene evolution of Lake Pannon between 11.0 and 10.5 Ma. Spores and pollen were used to analyse vegetation and climate while dinoflagellate cysts were used to reconstruct lake ecology. The section hosts primarily endemic brackish-water dinofla...

The Neogene Transylvanian Basin (TB), enclosed between the eastern and southern Carpathians and the Apuseni Mountains in Romania, is a significant natural gas province with a long production history. In order to improve the (bio) stratigraphic resolution, correlations and dating in the several 100-m-thick upper Miocene (Pannonian) succession of the...
Article
Marked climate warming during the early Toarcian oceanic anoxic event (T-OAE, ~182 Ma) has been shown to have had a significant effect on the global carbon cycle and biosphere. There is also emerging evidence that a primary short-term consequence of this warming was a marked increase in hydrological cycling. In this study, we have investigated loca...
Article
In the early Late Triassic, the Carnian Pluvial Episode (CPE) is a phase with increased siliciclastic influx into the marine-carbonate dominated depositional setting of the Western Tethys assumingly caused by a shift to more humid climatic conditions and increased continental runoff. Here, vegetation changes inferred from the palynological assembla...

The data presented in this article are related to the research article “Palynology and weathering proxies reveal climatic fluctuations during the Carnian Pluvial Episode (CPE) (Late Triassic) from marine successions in the Transdanubian Range (western Hungary)” (Baranyi et al. [1]). Palynological and palynofacies counts and mineralogical data are p...
Article
The development of high‐resolution 3D seismic cubes has permitted recognition of variable subvolcanic features mostly located in passive continental margins. Our study area is situated in a different tectonic setting, in the extensional Pannonian Basin system (central Europe) where the lithospheric extension was associated with a wide variety of ma...

Phase 1 of the Colorado Plateau Coring Project (CPCP-I) recovered a total of over 850m of stratigraphically overlapping core from three coreholes at two sites in the Early to Middle and Late Triassic age largely fluvial Moenkopi and Chinle formations in Petrified Forest National Park (PFNP), northeastern Arizona, USA. Coring took place during Novem...

The generally arid Late Triassic climate was interrupted by a wet phase during the mid-Carnian termed the Carnian Pluvial Episode (CPE). Quantitative palynological data from the Mercia Mudstone Group in the Wessex Basin (UK) reveal vegetation changes and palaeoclimate trends. Palynostratigraphy and bulk organic carbon isotope data allow correlation...

This paper presents the results of a mineralogical, petrographic and palynological study of selected Pannonian calcareous marl and sandstone samples penetrated by the Hódmezővásárhely–I (Hód–I) well, Endrőd Formation (Tótkomlós Member, cores 35 and 40, 5167.0–5183.0 m and 5468.0–5486.0 m, respectively); this formation is part of the Makó Trough of...
Conference Paper
Full-text available
Correlation of the palynological assemblages from the low latitude Chinle Formation in North America and the high latitude or Tethyan assemblages in Europe is difficult, because of vegetation provincialism as a result of climatic heterogeneity. This significant offset between the European and American palynofloras is the result of the generally hot...
Conference Paper
The Chinle Formation hosts a remarkable Norian terrestrial ecosystem with rich floral remains and vertebrate fossils. A floral turnover and reorganisation of riparian plant communities occurred in the Norian Chinle Formation of the American SW indicating ongoing climate change towards more arid climate and severe environmental perturbation. New pal...
Conference Paper
Froelichsporites traversei (Dunay & Fisher) Litwin, Smoot, Weems is a prominent palynomorph in the Upper Triassic of Northern America which is permanently found in tetrahedral tetrads. The distribution of the taxon seems to be restricted to the Upper Triassic of North America. It is an important biostratigraphic marker in the Norian and a rise in i...
Article
Palynological and paleobotanical investigation of bonebeds and other strata of the Csehbánya Formation from the vertebrate locality at Iharkút (Bakony Mts, Hungary) reveals well-preserved Santonian palynological assemblages dominated by the Normapolles group, with a minor component consisting of other angiosperm pollen, some gymnosperm pollen, and...

Project
North Croatian Basin (NCB) volcano-sedimentary complexes hold valuable information concerning the evolution of the Carpathian-Pannonian Region (CPR, Alpine–Carpathian–Dinaridic orogenic system) and Central Paratethys. However, there are still many open questions. PYROSKA project gathers an international research group with the main goal of applying a state-of-the-art multi-proxy approach in refining Miocene NCB syn-rift evolution. Timing of the initial Central Paratethys flooding of the NCB will be resolved by conducting time-stratigraphic correlations, that is by using integrated biostratigraphic and high-precision geochronological methods. Tephrochronology and volcanic provenance reconstructions of NCB pyroclastics will require volcanological and petrological determinations, U-Pb and Ar/Ar radiometric dating (EARTHTIME initiative), as well as mineralogical, geochemical and isotopic fingerprinting. Acquired high-resolution data will consequently enable more reliable regional reconstructions, including calibration and synchronization of Central Paratethys bioevents, as well as CPR magmatic evolution.
