“…Of special interest [1,[6][7][8][9][10][11][12][13][14][15] is the shell microsculpture of these small crustaceans -a strengthening skeletal formation of the thin valves with a certain type, or with several types, of ornamentation -, which is a possible diagnostic feature of conchostracan genera and species. The key role of shell microsculpture for conchostracan identification was first stressed by N.I.…”

The microsculpture of Permian and Triassic conchostracans from the Babii Kamen section (Western Siberia) was studied in order to determine the significance of microsculpture inthe taxonomy of conchostracan species. Five types of ornamentation have been identified in conchostracans from the Permian-Triassic reference section of Western Siberia (Babii Kamen section): pitted, nodular, reticulated, radial lirae, radial fringes. The results show that several microsculpture types are common for the genus level of conchostracans. Transition from one type of ornamentation to another was noted in three species: ?Megasitum lopokolense Novojilov, 1970, "Cornia papillaria" Lutkevich, 1937, and "Concherisma tomensis" Novojilov, 1958. The observed changes in the shell microsculpture types can be considered as a taxonomic feature for these three species and should form the base for future taxonomical revisions.

Nothocarapacestheria Rohn et al., 2014 was erected from the Upper Triassic–Lower Jurassic of Paraná Basin, Brazil. Here we describe a Nothocarapacestheria species, which is discovered from the Lower Jurassic Badaowan Formation in Xinjiang, northwestern China. The described species is characterized by: 1) almost the whole carapace ornamented with medium reticulations, 3–6 polygons per growth band, 20–60 μm in mesh diameter; 2) gradual raising of radially elongated reticulations in the distal region of the carapace, sometimes ending as radial lirae; 3) fine puncta in the mesh of reticulations. Through this study, we are able to infer that the distribution of Nothocarapacestheria was more widespread than previously thought, and that Euestheria sp. previously reported from the Lower Jurassic Badaowan Formation are probably poorly preserved or juvenile individuals of Nothocarapacestheria .
