Elasmobranchii are relatively well-studied. However, numerous phylogenetic uncertainties about their relationships remain. Here, we revisit the phylogenetic evidence based on a detailed morphological re-evaluation of all the major extant batomorph clades (skates and rays), including several holomorphic fossil taxa from the Palaeozoic, Mesozoic and ...

The impact of increasing atmospheric CO2 and the resulting decreasing pH of seawater are in the focus of current environmental research. These factors cause problems for marine calcifiers such as reduced calcification rates and the dissolution of calcareous skeletons. While the impact on recent organisms is well established, little is known about l...

Phetchabun National Geopark comprises varied geosites; one of the fluvial bedrock landforms distinguished here is Loei Dun. This shows many potholes in Mesozoic sandstone of the Nam Phong Formation (Khorat Group). A genetic study of the occurrence of the Loei Dun potholes lends it a higher geoheritage value. For the present study we did fieldwork a...

A new species, namely Doratomantispa pouilloni sp. nov., of the mantidfly subfamily Doratomantispinae, is described and illustrated from a complete individual preserved in mid-Cretaceous amber from Tanai, northern Myanmar. Doratomantispa pouilloni sp. nov. preserves nearly all the diagnostic characters of this subfamily, but differs from the two ot...
Jacobsoniidae is a species-poor family of minute polyphagan beetles distributed in tropical and subtropical regions. Both extant representatives of the family as well as fossils are rare. Here we describe a new fossil species, Derolathrus capdoliensis n. sp., from latest Albian-earliest Cenomanian Charentese amber from the Cadeuil deposit, Charente...
The Tannuola Terrane of Tuva, which is located in the northern part of the Central Asian Fold Belt, formed as a result of island-arc and accretionary-collision events in the Early Paleozoic. Further tectonic evolution of the terrane is related to a multiple reactivations of large and mostly normal fault structures. In the middle Paleozoic, the exte...
Abundant lake ice-rafted debris in Late Triassic and earliest Jurassic strata of the Junggar Basin of northwestern China (paleolatitude ~71°N) indicates that freezing winter temperatures typified the forested Arctic, despite apersistence of extremely high levels of atmospheric Pco2 (partial pressure of CO2). Phylogenetic bracket analysis shows that...
Two new genera, Burserphites and Mesoserphites, belonging to the subfamily Serphitinae (Serphitidae, Hymenoptera) are described from Burmese mid-Cretaceous amber. Two new species are erected within Buserphites n. gen.: B. applanatus, and B. myanmarensis, and five new species are established within Mesoserphites n. gen.: M. annulus, M. giganteus, M....
Although its geology is dominated by pre-Cambrian crystalline rocks, Sweden’s palaeobotanical research output is substantial. Over 150 years of dedicated research has yielded several hundred papers on Sweden’s palaeobotanical and palynological heritage spanning much of the geological column. Studies have targeted all categories of plant and protist...
