The Kargil Formation in the region of Ladakh (northern India) is known for its late Oligocene mammal fauna of both large mammals and rodents. New excavation in the area yielded a maxillary fragment of an insectivore with three premolars and two roots of a canine. The fossil record of the insectivores on the Indian subcontinent is as yet scanty. Bas...
Article
The new micromammal site of Beydere 3 represents a typical Anatolian MN3 fauna in the high diversification and abundance of Eumyarion. Notably, two Eumyarion species are new; combined, they make up almost half of the assemblage. While Eumyarion beyderensis sp. nov. shows simple morphology in upper molars, Eumyarion aegeaniensis sp. nov. shows a mor...
Article
Els Casots is one of the richest fossil vertebrate sites of the Vallès-Penedès Basin (Catalonia, Spain). It was discovered in 1989 and excavated briefly during the 1990s, resulting in the recovery of thousands of remains and the erection of several new mammal species. Excavations were resumed in 2018 and continue to date. Here we provide updated re...

The study of the phylogenetic relations between the species stands among the major topics of the natural sciences. In order to do that, paleontologists use the morphological similarity between the fossils. Studying the dental pattern has proven to be a valuable tool towards that goal, but problems may arise when dental morphology changes with wear....
Article
Full-text available
The new fossil micromammal assemblage of Çapak represents a mixture of both Anatolian and European faunal elements. The locality is very important for understanding faunal evolution in the less well-known time interval at the end of the early Miocene of western Anatolia. In Çapak, nine species of rodents and one species of ochotonid were encountere...
Article
Full-text available
Over the last half a century, a massive amount of data has been gathered on Neogene rodents of Europe. Using the NOW database, we analysed changes in generic diversity during the Neogene and the beginning of the Quaternary. Studies as the present are useful for exploring major changes in diversity, but the pitfalls are many and varied. Whereas the...
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 Vallès-Penedès Basin in Catalonia (NE Spain) forms a biogeographically important connection between central Europe and the Iberian Peninsula. Whereas this is well documented for the late middle and early late Miocene, the early Miocene sequence has received far less attention. New excavations yielded micromammal assemblages from the Ramblian an...
Article
The mammal locality of Gördes is only known from its test sample, as it has been subsequently destroyed. This small sample yielded a surprisingly rich assemblage, with five rodent species, four species of insectivore and a bat. Based on the rodent contents, the assemblage is assigned to Anatolian mammal zone D, equivalent to MN 3. One of the rodent...
Article
Two new small mammal assemblages from the abandoned Harami lignite mine, as an addition to previously known Harami assemblages, provide a better insight in the palaeoenvironments in Anatolia in local Biozone C (MN 2, early Miocene). Based on the new material, the Eumyarion assemblages are considered to consist of three, rather than two species, in...
Article
Full-text available
Terrestrial fossil records from the SW Anatolian basins are crucial both for regional correlations and palaeoenvironmental reconstructions. By reassessing biostratigraphic constraints and incorporating new fossil data, we calibrated and reconstructed the late Neogene and Quaternary palaeoenvironments within a regional palaeogeographical framework....
Article
Full-text available
An old test sample from the Sabuncubeli Formation (Manisa, Turkey) yielded an interesting faunule, which, however, up to now had never been described. In Bornova 183, now inaccessible, five species of micromammal were encountered: the hamsters Eumyarion aff. montanus, E. intercentralis and Cricetodon kasapligili, the squirrel Palaeosciurus fissurae...
Article
Full-text available
Unlike the rodents of the local zone C (MN 2) fauna of Gökler, the faunal list of the insectivores shows little surprises. The fauna is dominated by the gymnure Galerix saratji and the enigmatic talpid Suleimania ruemkae, both present in such numbers that for the first time the anterior dentition could be reconstructed. In the case of Galerix, thes...

Article
Few Quaternary herpetofaunas have been recovered from The Netherlands. Among these, the one coming from the early Pleistocene site of the Russel-Tiglia-Egypte pit near Tegelen is of particular interest , because it is the type locality of the recently described, last western European palaeobatrachid anuran, Palaeobatrachus eurydices. The large numb...

Full-text available
The knowledge of the Neogene and Quaternary fossil record of the insectivores, the small mammals included in the order Eulipotyphla, has been greatly improved in the last two decades. This improvement, linked to a refinement on the dating of many Spanish fossil localities, allows tracking the evolution of the insectivore assemblages during the last...
Article
Insular taxa, such as the late Miocene giant erinaceid Deinogalerix and the insular hominin Homo floresiensis, display a surprisingly primitive placement in cladistic analyses of their respective groups. This has led to speculations of early dispersal onto islands, not corroborated by biogeographical evidence. Insular evolution is notorious for vas...
Article
The recent paper by Elitez and Yaltırak (2016) proposes a revised Neogene stratigraphy that attempts to reconstruct tectonostratigraphic evolutionof the Çameli Basin area of the SW Anatolia (Fig.1), a region intensely studied by The Turkish Petroleum Corporation (TPAO) and The Geological Survey of Turkey (MTA) over past decades. Both TPAO and MTA p...
Article
The rich and relatively diverse fossil mammalian assemblage from Gökler is of special importance for understanding of faunal evolution in Central Anatolia. Large mammals were not recovered, but insectivores and rodents are abundant. The assemblage of rodents is studied in detail and comprises mainly diversified cricetids. Dormice are abundant, but...
Article
Once perceived as a continent-wide extinction event, doubts have been raised as to the severity and extent of the Vallesian Crisis. In this paper, we use the high-resolution late Aragonian to middle Turolian micromammal record from both the coastal Vallès-Penedès Basin and inland Calatayud-Teruel Complex to determine geographic extent of this late...

Çorakyerler Hominoid Site preserves exceptional fossil material of Anatolian Late Miocene since the beginning of 2000. Besides its unique hominoid record, the characterizing taxa for Corakyerler include also a large component of bovids, as well as diverse carnivores, equids and girafds. The micromammal fauna of Çorakyerler has received relatively l...
Article
The small mammal assemblages from Alto de Ballester 1 and 2 in the Rubielos de Mora basin represent a unique faunal assemblage from the late early Miocene (Ramblian, MN 3). Together, the assemblages yielded five species of rodents (Peridyromys murinus, P. aff. murinus, P. aquatilis, Pseudotheridomys aff. fejfari and cf. Steneofiber depereti), and n...

The systematics of Geotrypus is among the most debated within Talpidae, but the recent development of quantitative methods for shape analyses allows us to provide a thorough reconsideration of Geotrypus spp. In the present study, we perform a systematic revision of the species Geotrypus minor from the early Oligocene of Germany using two-dimensiona...
Article
The Valles-Penedes Basin (Catalonia, Spain) is classical area for the study of Miocene land mammal faunas. Nevertheless, the early Miocene part of the record has deserved little attention as compared to younger intervals. Most notably, the small mammals of this age have not been described in detail, consequently hampering the correlation of the Val...
Article
Full-text available
Over the last decade, important progress has been made in the study of the mammal successions from Hungary and Romania. A critical review of the taxonomy of the published small mammals is provided herein, as well as some new data and an overview of the accompanying vertebrate fauna (excluding fishes) in their stratigraphic context. In addition, the...
Conference Paper
Sedimentary basins in Anatolia preserve a rich record of Neogene terrestrial environments at the crossroads between Asia and Europe. Deciphering the geological evolution of these basins is essential for understanding how this fine record came to be preserved. In a reciprocal fashion, the fossil record allows for correlating between basins and for r...
Article
The fossil record from the Carpathian area plays a key role for the understanding of the processes leading to the faunal interchanges between western Europe and Asia Minor during the late part of the Middle Miocene. Important mammal successions are now availablefrom the Central Paratethys, especially Hungary and Romania. Here, we present the curren...
Article
Disarticulated remains of palaeobatrachids coming from the early Pleistocene (Gelasian) of Tegelen (The Netherlands) are here described and referred to the new species Palaeobatrachus eurydices. The new species has been included in the first comprehensive phylogenetic analysis considering all known species of the genus Palaeobatrachus and was found...

Corakyerler Hominoid Site has produced one of the largest and most diverse faunas from the late Miocene of Anatolia since the beginning of 2000. Besides its unique Hominoid record, the characterizing taxa for Çorakyerler include also a large component of bovids, as well as diverse carnivores and other ungulates. However, over 3000 fossil specimen a...
Article
The eastern Mediterranean has yielded some textbook examples of insular evolution among large mammals such as the world's smallest hippopotamus and mammoth. By contrast, gigantism among small mammals is limited, with the exception of the early Pleistocene murid Kritimys from Crete. The large body size of insular rodents can be related to an energet...
Article
The fossil record of the Iberian insectivores forms a subset of those found in central Europe. Comparison of the late early to early late Miocene record of the two areas shows that, particularly during the late Early Miocene, central European taxa have transient occurrences in Spain. Most taxa appear earlier and survive longer in central Europe. A...

Vegetation and climate changes during the late Pliocene and early Pleistocene in SW Turkey – Response to Comments by Elitez et al., Quaternary Research, 84, pp. 448–456 - Volume 85 Issue 3 - Gonzalo Jiménez-Moreno, Hülya Alçiçek, Mehmet Cihat Alçiçek, Lars van den Hoek Ostende, Frank P. Wesselingh
Article
We present an updated taxonomy and faunal distribution of the micromammal fossil record from the Aragonian and Lower Vallesian of the Calatayud-Montalbán Basin. The analysed record includes the orders Rodentia, Eulipotyphla, and Lagomorpha. The pattern of species turnover shows seven major faunal events, which are correlated with major climate chan...
Article
Pollen analysis was done on lacustrine sedimentary sequences dated by micromammals as late Pliocene–early Pleistocene that outcrop in two Neogene graben basins from SW Turkey. This study shows vegetation changes from steppe-like to more forested environments, very similar to the cyclic oscillations related to late Pleistocene glacial–interglacial c...

At the time of its discovery, over 25 years ago, the Greek locality of Aliveri preserved the easternmost occurrence for the early Miocene of cricetodontine hamsters such as Cricetodon, Megacricetodon and Democricetodon. As knowledge on the early Miocene history of the eastern Mediterranean increased, the faunal composition became more enigmatic, be...
Article
The locality of Bıçakçı (Çameli basin, Anatolia) has yielded a diverse fauna of micromammals. The arvicolines are the most diverse and abundant group. Their stage in evolution shows that the fauna is late Villanyian in age and can be placed in the lower part of the zone P of the Anatolian Neogene biozonation. Thus, it is on the brink of the importa...

For palaeontologists, the challenge is to reconstruct biodiversity patterns of the past. Mammal richness in grids is used to assess the stability of biodiversity hotspots and document changes over time in Europe for Mammal Neogene units 3 to 11 (19.5 to 7.6 Ma), early to late Miocene. The maps clearly show the patchiness of the fossil record. As th...
