The metacopines represent one of the oldest and most important extinct groups ostracods, with a fossil record from Mid-Ordovician to Early Jurassic. Herein, we report discovery representative group three-dimensionally preserved soft parts. specimen—a male Cytherellina submagna —was found in Devonian (416 Ma) Podolia, Ukraine. A branchial plate (Bp) cephalic maxillula (Mx), pair thoracic appendages (walking legs), presumed furca (Fu) copulatory organ are preserved. material also includes...
Ostracods are by far the most abundant living group of arthropods in fossil record. Traditionally, eridostracines were classified as members Class Ostracoda. They have also been considered to represent extinct marine spinicaudatan (conchostracan) branchiopods. The ostracod affinity Eridostracina is evident a number features such muscle scars pattern, hinge structure, presence an adductorial sulcus reflected ridge on internal surface and separation at dorsal margin successive valves. might be...
A family-level classification of microconchid tubeworms (Order Microconchida, Class Tentaculita) is proposed here for the first time. Based on distinct tube microstructure and/or ontogeny, following families are defined: Palaeoconchidae (tubes having microlamellar structure deflected by pseudopunctae), Microconchidae punctae that manifested exterior as pores), Helicoconchidae showing lateral budding and binary fission budding), Punctaconchidae large large, pores). This necessary because it...
The central muscle scar field of the beyrichioidean palaeocopid ostracodes includes an adductor composed many polygonal scars, a long mandibular eight individual and oval frontal scar. Probably, as in extant ostracodes, scars served attachment points for closing muscles well chitinous supporting structures from appendages. fulcral depression, on which dorsal apex mandible pivots recent has also been recognized Early Carboniferous beyrichiids paraparchitids.The pore systems beyrichioideans...
AbstractSmall encrusting marine organisms belonging to the genera Ascodictyon, Eliasopora and Vinella were originally described as ctenostome bryozoans. Well-preserved ascodictyid specimens from Early Middle Devonian of Poland allow us exclude such an affinity due absence any aperture in vesicles for protrusion or withdrawal lophophore during feeding. The bryozoans are soft-bodied, but filaments have calcified walls. Reinterpretation stellata (Nicholson & Etheridge, Citation1877),...
New microfossil and magnetostratigraphical data as well geochemical clay mineral weathering indices are documented from the uppermost Jurassic Owadów–Brzezinki palaeontological site in central Poland. The newly discovered chitinoidellid assemblage of lowermost part section previously middle assigned, respectively, to Dobeni Boneti Subzones Chitinoidellidae Zone. same succession is correlated magnetosubzone M20n.2n. new allow refinement Tithonian stratigraphical scheme including an assignment...
Colonies of boring ctenostome bryozoans and microborings "fungi" that occur in the Early Devonian (Lochkovian, ~416 Ma) Podolia, western Ukraine, have soft-tissue preserved by phosphatization.These comprise exceptional three-dimensional body walls feeding zooids with probable parietal muscles inserted on cystid wall, setigerous collars twisted within vestibulum.The presence this ctenostomes proves existence feature for more than 416 Ma evolution.Phosphatized remains zooid are interpreted as...
Carapace morphology was studied biometrically for each instar in a series of populations Mojczella Olempska 1988 from the Ordovician strata exposed Mójcza, Holy Cross Mountains, Poland. Phosphatic coatings ostracod valves occur there abundance top Arenig to Late Caradoc. The lineage shows smooth acceleration ontogenetic expression junction crests C1 and C3, which originally were separated throughout ontogeny, while latest separation preserved only earliest moult stage. Moreover, velar...
Abstract The calcareousmicrofossil assemblage from Middle Miocene strata of SHALDRIL Site NBP0602A−5D consists benthic foraminifera, ostracods, bivalves, and gastropods, is interpreted as shallow−water. It appears to be reworked but its age probably similar the host sediment, which contains only rare, fragmented, agglutinated foraminifera. Most calcareous taxa are uncertain taxonomic affiliation, due scarcity Ceno− zoic microfossils this fromWest Antarctica, also very different paleohabitat...
Abstract A Lower Devonian silicified ostracod fauna has been recovered from limestone interbeds in the Büyükdere section of Kozyatağı Member Pendik Formation. Forty-one species belonging to 33 genera have recognized. Twenty-three are already known, and 15 described open nomenclature. One genus three ( Omerliella rectangulata gen. et sp. nov., Microcheilinella istanbulensis nov. Roundyella goekchenae nov.) described. Silicified larval stages trilobites, agglutinated foraminifers conodonts...
