The genus Macrocnemus is a member of the Tanystropheidae, clade non-archosauriform archosauromorphs well known for their very characteristic, elongated cervical vertebrae. Articulated specimens are from Middle Triassic Alpine Europe and China. Although multiple articulated known, description cranial morphology has proven challenging due to crushed preservation specimens. Here we use synchrotron micro computed tomography analyse specimen type species bassanii Besano Formation Monte San...
Saber-toothed cats (Machairodontinae) were wide-spread, top predators of the Pleistocene terrestrial ecosystem. In Europe, they previously known only from early and middle (Adam, 1961; Turner Anton, 1997), their fossils are always extremely rare. The previous youngest record was Steinheim a/d Murr, Germany, where an upper canine Homotherium found in a stratum dated to ca. 0.3 Ma 1961). this paper, we describe well-preserved den- tary latidens by 14 C be late Pleisto-
The Cretaceous Kem beds of Morocco and equivalent in Algeria have produced a rich fossil assemblage, yielding, amongst others, isolated sauropod teeth, which can be used species diversity studies. These Albian-Cenomanian (∼113–93.9 Ma) strata rarely yield body fossils, therefore, teeth help to elucidate the faunal assemblages from North Africa, their relations with those contemporaneous geographically close assemblages. Eighteen three localities (Erfoud Taouz, Morocco, Algeria) are studied...
Abstract Humans colonized the Balearic Islands 5–4 ka ago. They arrived in a uniquely adapted ecosystem with mountain goat Myotragus balearicus (Bovidae, Antilopinae, Caprini) as only large mammal. This mammal went extinct rapidly after human arrival. Several hypotheses have been proposed to explain extinction of M. . For present study ancient DNA analysis (Sanger sequencing, Roche-454, Ion Torrent), and pollen macrofossil analyses were performed on preserved coprolites from , providing...
An attempt is made to correlate the history of paleoclimate evolutionary Soricidae.Therefore, and ecophysiology family are briefly outlined.It concluded that factors temperature humidity play a crucial role in ecology shrews.It thus conceivable Soricidae influenced by climatic changes.It supposed (cooling desiccating) event around Miocene/Pliocene boundary responsible for extinction subfamily Crocidosoricinae.The Soricinae exploited then vacant positions, strongly radiated during...
The rich early Miocene small mammal assemblage from Montalvos2, collected lacustrine deposits directly overlying the basement, is unique within Teruel Basin, a basin that otherwise well known for its late Miocene/Pliocene faunas. presence of Democricetodon decipiens, Megacricetodon primitivus, Eumyarion and Ligerimys ellipticus enables correlation with local biozone Ca (approx. 16.3 Ma, MN4). high percentage ochotonids in Montalvos2 remarkable, phenomenon to occur older assemblages adjacent...
The number of cervical vertebrae in mammals is highly conserved at seven. We have shown that changes this are selected against due to a coupling with major congenital abnormalities (pleiotropic effects). Here we show the incidence abnormal vertebral numbers Late Pleistocene mammoths from North Sea high (33.3%) and approximately 10 times higher than extant elephants (3.6%). Abnormal were presence large ribs on seventh vertebra, which deduced rib articulation facets sixth (posterior side)...
The Kem Group of Southeastern Morocco, North Africa, is well known for theropod remains, especially isolated teeth. Here, a collection teeth assessed diversity using combination linear discriminant, phylogenetic, and machine learning analyses the first time. results confirm earlier studies on diversity, with referred to Abelisauridae, Spinosaurinae, Carcharodontosauridae. A single tooth ascribed non-abelisauroid ceratosaur or megaraptoran may represent enigmatic averostran Deltadromeus....
Abstract We investigate the stratigraphy of Neogene and Quaternary intervals Schelphoek borehole (Schouwen, Zeeland, Netherlands). The Breda Formation (Miocene-Zanclean) contains three sequences separated by hiatuses. Oosterhout (Zanclean-Piacenzian) at least two sequences. This formation is overlain seven Gelasian Maassluis that almost certainly represent glacial cycles. lowermost are provisionally assigned to Praetiglian (MIS 96, MIS 98 100). A large hiatus exists between top base late...
Abstract Chondrichthyan and actinopterygian fish remains from Rhaetian (c. 208.05–201.36 Ma) or perhaps Late Norian deposits in the Winterswijk quarry are described. The most abundant taxon is Gyrolepis albertii , followed by chondrichthyan Lissodus minimus . Furthermore, palaeopterygian actinopterygians Saurichthys longidens Birgeria acuminata some teeth of neopterygians Sargodon tomicus ‘ Lepidotes ’ sp. indeterminate pycnodontiforms recorded addition to chondrichthyans Rhomphaiodon minor...
Despite its vernacular names (e.g.'woodlice') Isopoda is a group with mostly aquatic species, most species living in marine environments.The fossil record for isopods compared to other groups of Eucrustacea relatively sparse.This applies even more the Triassic.While Jurassic well represented by fossils, only eight have previously been described from Triassic.In this study three new are two field sites Europe: Obtusotelson summesbergeri sp.nov.and Discosalaputium aschauerorum sp.nov.from...
