Finally, the present results suggest caution about the dangers of using potentially homoplastic eggshell characters in eggshell parataxonomy.Fosilele depozitelor maastrichtiene din Bazinul Hațeg dezvăluie prezența unor sisteme paleoecologice complexe, în cadrul cărora există reprezentanți ai multor clade majore. 5).diagnostic elements as well, including the type,figs. July 2015 However, selection of the,remains occurred during this transport by,exception to this is represented by the lizard,remains, included in category A, but derived,from strictly terrestrial taxa, suggesting the,lizards inhabited closely located microhabitats,while other terrestrial taxa lived farther from,the site of the burial.
In the Haţeg basin, South Carpathians, a thick continental sequence accumulated during the Maastrichtian. The data provided the description of 83 palynomorphs, including 8 algae, 10 fungi, 17 ferns, 1,We present biostratigraphical and palaeoenvironmental analyses based on palynology and palynofacies of marine and terrestrial deposits that crop out in the central and northwestern part of the Haţeg Basin.
The potential functional significance of eggshell ornamentation, lost in most modern birds, requires further study, and experimental zoological approach may shed light on this issue. Diverse seed and palynomorph.eeds are referred to indeterminate angiosperms,pollen dominate the palynological assemblage.

On the basis of a cladistic analysis, this Ha{\c t}eg theropod material is referable to Dromaeosauridae (thereby extending the stratigraphic range of the clade to the latest Cretaceous). Finally, the presence of well-preserved eggshells recovered from two different sites representing different depositional environments provides further evidence for previous taphonomic and sedimentological conclusions, and also expands our knowledge of the special conditions that allowed the preservation of these delicate eggshell fragments.Bioerosion on fossil bones offers significant insights into both trophic relationships of ancient ecosystems and vertebrate taphonomy. Turonian-Lower Senonian,planktonic foraminifera from the Ohaba-Pui-,krokodilok, dinoszauruszok, pteroszauruszok és,Pacltova, B., 1966.
These specimens (a frontal and fused parietals) are described and subjected to phylogenetic analyses.
The above observations suggest that,experienced either only very short transport,and short-term subaerial exposure or none at,all (excepting possibly the rare isolated teeth,that, being among the most resistant elements,of the skeleton, can better withstand transport,Budurone MFS is relatively diverse, as it.includes at least 12 different vertebrate taxa.The most diverse group is that of the fishes,with 3 different taxa, which is outstanding.absent altogether. n order to constrain the age of the Upper Cretaceous continental Densuş-Ciula Formation from the Haţeg basin, South Carpathians, and correlate it with the other continental unit that occurs in the region, the Sânpetru Formation, we separated and
All these algorithms pretend an important volum of computing (and special computing programms).
The palynofacies constituents used to reconstruct the depositional environments suggest that during the Santonian–early late Campanian, strata were laid down in an inner-outer neritic environment (with some fluctuations of water depth). Sedimentological study of the locality suggests,dplain pond or marsh.

The paleobiogeographic implications of the Haţeg dromaeosaurid on European, North American, and Asia origins for the clade are discussed, as is the idea that the Late Cretaceous islands of Europe acted as a refugium for the last known dromaeosaurids.UR - http://www.scopus.com/inward/record.url?scp=0345033130&partnerID=8YFLogxK,UR - http://www.scopus.com/inward/citedby.url?scp=0345033130&partnerID=8YFLogxK,JO - Neues Jahrbuch fur Geologie und Palaontologie - Abhandlungen,JF - Neues Jahrbuch fur Geologie und Palaontologie - Abhandlungen,"We use cookies to help provide and enhance our service and tailor content.
