    Opis:
    The Middle Devonian was an exceptional time for foraminiferal evolution because of the emergence of the first true calcareous multilocular taxa. Despite being key forms for an understanding of the origin of foraminiferal multilocularity, which is one of the most intriguing events in the evolutionary history of the group, they are largely unstudied. These unique foraminifera, including representatives of the genera Cremsia, Moravammina, Pseudopalmula, Semitextularia, and Vasicekia, are presented herein as well as foraminifer-like microfossils of uncertain biological position. The studied material comes from the Middle Givetian strata of the Miłoszów section and the Eifelian part of the Grzegorzowice-Skały section (Holy Cross Mountains, Poland). Described isolated specimens are in an exceptionally good state of preservation on a worldwide scale, which enabled the detailed analysis of test morphologies, complementing previous papers based on less well-preserved material. The suggested systematics of the foraminifera collected attempts to revise scarce taxonomic data that is still under debate, especially the classification of Moravammina, Cremsia, and Vasicekia. The Devonian foraminifers presented were prominent endobenthic and epibenthic inhabitants of common organic coral-stromatoporoid buildups. Palaeobiogeographical records show that during the Middle Devonian, the studied forms extended their exclusive European distribution into further Laurussian shelves and shallow seas, located in the northern and southeastern parts of the Rheic basin. This assumes that such assemblages may be used as palaeoenvironmental indicators. However, at present, their correlative potential is unknown.

    Opis:
    Sixty-two Middle Devonian brachiopod species are described on the basis of >1300 specimens from the Taboumakhlof Formation (and subordinately probably also from the top of the El Otfal Formation) at Madne el Mrakib (middle to late Eifelian or early Givetian?), Aferdou el Mrakib (late Eifelian to middle Givetian), and Guelb el Maharch (early Givetian) on the southern edge of the MaÎder Syncline (eastern Anti-Atlas, Mo- rocco). Representatives of Craniida (2 taxa), Strophomenida (5), Productida (2), Orthotetida (2), Orthida (5), Pentamerida (5), Rhynchonellida (9), Atrypida (14), Athyridida (7), Spiriferida (9), and Spiriferinida (2) are present. The fauna is dominated quantitatively by the Atrypida (24% of taxa, about the half of specimens, and the commonest species Atryparia dispersa making up about 13% of the material); the Rhynchonellida (16% of taxa, about one-sixth of specimens) are the second largest order. A new genus of the family Pugnacidae (order Rhynchonellida), Paulinaerhynchia, is proposed with the type species P. paulinae gen. et sp. nov. from Maharch; it is closest to Pugnax, from which it differs in distinct costation, lack of a dorsal septum and septalium, and rudimentary dental plates. Desquamatia (D.) deserti sp. nov., a large and finely costate representative of the genus, is described also from Maharch. Antirhynchonella and Glosshypothyridina are reported for the first time or con- firmed to be present in the Givetian. Forty (possibly up to 46) species (71 or possibly up to 82% of the taxa identified at the species level) are present also in either Eifel (Germany) or the Holy Cross Mountains (Poland). Such a high ratio of species in common attests to unconstrained faunal exchanges among benthic faunas between the northern and southern shores of the Variscan Sea during the Middle Devonian. This favours the palaeogeo- graphic hypothesis of a narrow Variscan Sea.

    Central Iran
    Opis:
    Nine species of gastropods are reported from the Bajocian (Middle Jurassic) part of the Badamu Formation of Central Iran. This is the first report of a gastropod assemblage of this age from the shelves of the Kimmerian Continent. Seven species belong to the Vetigastropoda and two to the Caenogastropoda. Two new species, the pleurotomariid Bathrotomaria iranica sp. nov. and the eucyclid Eucycloidea badamuensis sp. nov., are described. The remaining species are left in open nomenclature owing to poor preservation. The composition of the gastropod association is strongly reminiscent of other Tethyan gastropod faunas, in particular those from the southern shores of the Tethys (India and Arabia) and from southern Europe. This indicates a relatively uniform distribution of gastropod faunas along the Middle Jurassic shores of the western Tethys.

    Opis:
    Tunethyris blodgetti sp. nov. from the Triassic Saharonim Formation, Makhtesh Ramon, an erosional cirque in southern Israel, is erected on the basis of a suite of 39 articulated specimens. The shells are very strongly sulciplicated, a feature that seems to be more prevalent in the Mesozoic than the Palaeozoic. The Saharonim Formation was deposited under quasi-normal, calm, relatively shallow marine conditions. Faunal constituents of the Saharonim Formation include conodonts, ostracods, foraminiferans, bivalves, cephalopods, gastropods, echinoderms and vertebrate remains that belong to the Sephardic Province and are diagnostic of the Middle Triassic series of Israel. The faunal composition and shallow depositional environment of the strata may help differentiate the Sephardic Province from the Germanic Muschelkalk and the Alpine Tethyan faunas to the north.

    Opis:
    The origin of reptiles in the tetrapod footprint record has always been a debated topic, despite the great potential of fossiliferous ichnosites to shed much light on reptile origins when compared to the much less extensive skeletal record. This is in part due to an unclear ichnotaxonomy of the earliest tracks attributed to reptiles that has resulted in unreliable trackmaker attributions. We comprehensively revise the earliest supposed reptile ichnotaxon, Notalacerta missouriensis, based on a neotype and a selection of well-preserved material from the type locality and other sites. A synapomorphy-based track-trackmaker attribution suggests eureptiles and, more specifically, ́protorothyridids ́ such as Paleothyris as the most probable trackmakers. A revision of the entire Pennsylvanian-Cisuralian record of this ichnotaxon unveils an unexpected abundance and a wide palaeogeographical distribution. The earliest unequivocal occurrence of Notalacerta is in the middle Bashkirian (early Langsettian) at the UNESCO World Heritage Site, Joggins Fossil Cliffs (Joggins, Nova Scotia, Canada). This occurrence also coincides with the earliest occurrence of reptile body fossils (Hylonomus lyelli), which are found at the same site. Notalacerta is abundant and widely distributed during the Bashkirian, mostly in sediments deposited in tidal palaeoenvironments, and less common in the Moscovian and Kasimovian. During the Gzhelian and Asselian, Notalacerta occurrences are unknown, but it occurs again during the Sakmarian and is widespread but not abundant during the Artinskian, mostly in fully continental palaeoenvironments.

    Opis:
    The Prosopidae is an extinct family, consisting mostly of Mesozoic species. Most probably it accommodates the ancestors of all brachyurans in the large sense. The family appeared in the Late Pliensbachian and disappeared at the Early Palaeocene. Evolution of the Prosopidae, and therefore, brachyuran evolution started on Middle Jurassic, shallow, soft bottom marine environments. The world-wide Callovian transgression made possible the formation of bioherms and reefs in the Late Jurassic, creating ecological niches for the rapidly differentiating prosopids. These crabs migrated rapidly all over Europe in the Oxfordian and began to flourish and massively occupied sponge megafacies from Portugal to Poland. In the Kimmeridgian, the area of known prosopids shrank, which has probably been connected with decreasing of the reef facies. In turn, a Tithonian regression in the per-Tethyan area resulted in changes of habitats and in colonisation of the coral reefs. When reef facies retreated at the Jurassic-Cretaceous boundary, the favourable conditions for crab development also vanished, so the known Cretaceous prosopids are rare and spatially dispersed. In Tertiary, the closely related descendants of them, homolodromiids, inhabited preferably soft muddy bottoms in deeper, colder waters.
    Kraby z rodziny Prosopidae, reprezentowane są prawie wyłącznie przez gatunki mezozoiczne. Z filogenetycznego punktu widzenia, są one prawdopodobnie przodkami wszystkich pozostałych gatunków krabów. Przedstawiciele tej rodziny znani są od późnego pliensbachu do wczesnego paleocenu. Ewolucja prosopidów, a poprzez to ewolucja pozostałych krabów, rozpoczęła sią w środkowojurajskich, płytkich środowiskach morskich o miękkim charakterze dna. Ogólnoświatowa transgresja kelowejska stworzyła dogodne warunki do powstania różnorodnych bioherm i raf w późnej jurze, które stanowiły nisze ekologiczne dla szybko różnicujących się dzięki temu krabów z rodziny Prosopidae. Kraby te migrowały gwałtownie na całą Europę w oksfordzie, masowo zasiedlając megafację gąbkową i są obecnie znajdowane w utworach tej facji od Portugalii do Polski. W kimerydzie obszar występowania prosopidów wyraźnie się skurczył, co było prawdopodobnie związane ze stopniowym zanikiem tej facji. Z kolei w tytonie regresja w obszarach perytetydzkich spowodowała zmianę środowiska życia krabów i kolonizację przez nie raf koralowych. Dogodne warunki dla rozwoju tych krabów gwałtownie się pogorszyły blisko granicy jury i kredy (zanikanie facji rafowych) skutkiem czego kredowe prosopidy są rzadkie i geograficznie rozproszone. W trzeciorzędzie najbliżsi potomkowie rodziny Prosopidae - kopalni przedstawiciele rodziny Homolodromiidae - zasiedlili środowiska miękkich den głębszych i zimniejszych mórz.
