New species of Asperarca (Bivalvia, Arcidae) from the Upper Eocene of Ukraine
Pleiades Publishing Ltd - Tập 48 - Trang 575-579 - 2014
Two new species of Asperarca, A. acuta and A. microida, from the Upper Eocene of the Ukraine (Dnepropetrovsk, Mandrikovka Beds) are described. This genus is recorded for the first time in the Paleogene. The most ancient previously known records of Asperarca were dated Miocene.
A Record of Phylactolaemata from Late Cenozoic Continental Deposits of Northern Eurasia and North America
Pleiades Publishing Ltd - - 2022
Fossil statoblasts of Phylactolaemata were found in several Late Cenozoic sections of Eurasia and North America. Phylactolaemata has great potential for paleoenvironmental reconstructions, but the taxon is still rarely used. Here we give examples of environmental reconstructions based on fossil statoblasts. These records suggest an aquatic origin of the sediments and make it possible to distinguis...... hiện toàn bộ
A new genus and species of the cockroach family Blattulidae from Lebanese amber (Dictyoptera, Blattina)
Pleiades Publishing Ltd - Tập 42 - Trang 43-46 - 2008
A new genus and species of the cockroach family Blattulidae, Ocelloblattula ponomarenkoi gen. et sp. nov., are described from the Early Cretaceous Lebanese amber. In the wing venation, the new genus is extremely similar to the Jurassic genus Blattula Handlirsch, differing from the latter in a number of characters in its body structure. This find reveals much about the body structure of the extinct...... hiện toàn bộ

The Kasimovian Stage is a stage in the Pennsylvanian Subsystem, originally recognized in Russia.

Structural aberrations in the cup in cladid crinoids from the carboniferous of the Moscow region
Pleiades Publishing Ltd - Tập 48 - Trang 1243-1257 - 2014
Aberrations of the discrete characters of dorsal cups and arms in the Carboniferous crinoids of the Moscow region, mainly represented in the collections of the Paleontological Institute, are studied. Aberrations are unevenly distributed across different genera, from the total absence in a sufficiently large sample to nearly 10%. Aberrations in infrabasals, basals, radials, and anal plates as well ...... hiện toàn bộ
The Koryak phase of the Flora development in the Northern Pacific frame
Pleiades Publishing Ltd - Tập 43 - Trang 702-710 - 2009
The Koryak phase of the floristic development in the Northern Pacific frame is discussed. Newly obtained data on the Koryak Flora from the Amaam Lagoon area (Northeastern Russia) and Paleocene floras of the Northern Alaska have extended geographic and temporal ranges of the phase. Interregional statuses of the Koryak phase and phytostratigraphic horizon based on this phase, which is traced over th...... hiện toàn bộ
