Ischnacanthiform acanthodian dentigerous jaw bones from the Lower Devonian (Late Lochkovian) of Podolia are described for the first time. One new genus and one new species are established. Podoliacanthus gen. nov. is diagnosed as having small−sized jaw bones, the presence of specific accessory cusps/denticles on the medial side of teeth of the lateral tooth row, and groups of denticles forming the lingual tooth row. Podoliacanthus zychisp. nov. is distinguished in having elongated slender jaw bones and lateral teeth with one medial side denticle. Besides, three species are described in open nomenclature: Podoliacanthus sp. 1, while similar to Podoliacanthus zychi sp. nov., differs in having stronger posterior inclination of the teeth tips and presence of well developed flanges of the teeth, P. sp. 2 has quite robust jaw bones and teeth with two medial side denticles, and Podoliacanthus sp. 3 has small narrow jaw bones and teeth with three medial side denticles. Morphology of the lingual tooth row is considered to be a diagnostic feature of generic and higher taxonomic levels, while accessory medial cusps/denticles of the teeth are regarded as diagnostic features at species level. The new genus also occurs in Upper Silurian or Lower Devonian deposits of North Greenland. Preservation of the jaw bones possibly depends on their secondary mineralization.

Upper Eocene Foraminifera of East Poland and their palaeogeographical meaning

Foraminiferal assemblage found in Upper Eocene deposits from Siemień (Eastern Poland) includes over 70 species. This assemblage lived in cold shelf waters 80-100 m deep. The foraminifera-bearing deposits may be correlated with lower part of marls of Kiev stage from Ukraine, representing the lower horizon of the Upper Eocene and/or the Middle-Upper Eocene junction beds. Foraminiferal assemblage from Siemień beds is entirely different from that known from the stratotype of the Bartonian. Marine transgression responsible for deposition of Siemień beds presumably reached the area of Poland from the East, utilizing old tectonic frame: Dnepr-Donetz aulacogen and its extensions. This is confirmed by a marked similarity of foraminiferal assemblages as well as composition of heavy minerals present in deposits of Siemień beds.

Borings formed by Late Cretaceous endobiontic foraminifers within larger benthic foraminifers

Considering the fossil record, foraminifers constitute one of the most ubiquitous groups in marine deposits due to a high preservation potential of tests. Moreover, borings appear to be widely distributed in the tests. Findings of the borings have potential usefulness as palaeoecological markers and can be significant for taphonomical studies of foraminifers. Formal naming of the borings is needed to further their usefulness, and therefore a new ichnotaxon Curvichnus semorbis igen. et isp. nov. is erected.

Mat-forming coccoid cyanobacteria from Early Silurian marine deposits of Sudetes, Poland

nr 1
Mass occurrence of mats comprised of benthic coccoid cyanobacteria is reported from early Silurian black radiolarian cherts exposed at Żdanow village (Bardzkie Mountains, Sudetes, southwestern Poland). The cherts contain laminated organic matter representing degraded benthic coccoid cyanobacterial mats. The remains of cyanobacteria occur as laminated agglomerations of variously preserved subglobular colonies composed of spherical cells of variable size and numbers. The morphology of remnants of cells and their mucilaginous envelopes, structure of colonies, and particularly the presence of small granular structures resembling reproductive cells known in extant coccoid cyanobacteria as baeocytes, permit to compare the Silurian microbiota with modern cyanobacteria assigned to the genera Stanieria or Chroococcidiopsis.

A new Pliensbachian [Early Jurassic] neoselachian shark fauna from Southern Sweden

Hettangian to Pliensbachian neoselachian tooth assemblages from marine deposits in northwest Europe are dominated by palaeospinacids. In the Toarcian, elasmobranch faunas tend to be more diverse and several other neoselachian groups have their first occurrence. A small, but surprisingly diverse, neoselachian tooth assemblage, comprising seven taxa, has been extracted from Pliensbachian sediments within the Rya Formation in southern Sweden. The fauna includes five synechodontiform species; Synechodus occultidens, S. enniskilleni, 'Synechodus' sp., Paraorthacodus sp., and Sphenodus sp. The remaining two species include Hexanchidae indet. and Agaleus dorsetensis. The exclusively Early Jurassic A. dorsetensis is separated from all other neoselachians on the basis of tooth morphology and is here included in the new, monotypic family Agaleidae nov. The assemblage from the Rya Formation is the first selachian fauna to be recorded from the Jurassic of Sweden and it has a composition quite different from contemporary faunas found in other areas of Europe. The neoselachian part of the fauna is more diverse while hybodont sharks are represented solely by a single species.

Opoka, as a silica-calcite sedimentary rock, occurs in south-eastern Europe and Russia. Stratigraphical studies down to 8 m depth were performed in Bełżec, Poland, where samples were taken for further analyses. Vertical layers represented a heavy-weight opoka consisting of relatively more CaCO3 than the horizontal layers of lightweight opoka dominated by SiO2 . Opoka had a mean bulk density of 1.34 g/cm3, a porosity of 44.5 % and a specific surface area of 64 m2 /g. Opoka, especially after heated to over 900℃ can be used as reactive filter media for phosphorus removal. Maximum sorption capacity was 119.6 g PO4 -P/ kg. Element analysis of the rock did not reveal any anomaly from that expected, and it was concluded that its element content does not devaluate opoka as a sorbent used in ecological wastewater treatment .
