Text-fig. 11. Eospondylus cf. primigenius (STÜRTZ) "Prastav" quarry at Praha-Holyně, Třebotov Limestone, Lower Devonian, Dalejan, NM L 36905, x 65. Overlay of proximal and distal articulations. Upper photo is proximal surface with distal bird-like articulation knobs superposed in ink. Lower photo is distal surface with proximal articulation knobs superposed in ink. The architecture of articulation surfaces is both zygospondylous and auluroid. This architecture occurs also in vertebrae of Furcaster and indicates that families Eospondylidae and Furcasteridae are closely related. in Isolated Ossicles Of The Family Eospondylidae Spencer Wright, 1966, In The Lower Devonian Of Bohemia (Czech Republic) And Correction Of The Systematic Position Of Eospondylid Brittlestars (Echinodermata: Ophiuroidea: Oegophiurida)

Text-fig. 2. Eospondylus primigenius (STÜRTZ) Bundenbach, Eschenbach-Bocksberg quarry, Lower Devonian, Lower Emsian (Zlichovian), Hunsrück Slate,, NM S 4764, x 3. Specimen with ventral arm coiling. The specimen is on its dorsum in slate with all five rays curled ventrally inward toward mouth area on underside of disk. Barely visible are tips of two jaws; slightly exposed are proximal parts of rays in oral view extending outward from disk. The location of abrupt ventral bending of rays is indicated by emergence from slate of five rays in aboral view that point inward toward buried disk. Based on ventral bending of rays and intimate association with crinoids Eospondylus has been interpreted as stratigraphic first occurrence of Order Euryalida, which contains epizoic gorgonocephalid and euryalid basket-stars of modern oceans. This status is rejected using new evidence from isolated vertebrae.

The WRF model output for selected foehn events at the northern foreland of the Moravian-Silesian Beskids, Czech Republic

This dataset includes three output files from the Weather Research and Forecasting (WRF) model in the NetCDF format. The files are valid for three selected foehn events which affected the northern foreland of the Moravian-Silesian Beskids, Czech Republic and allows a deeper analysis of mechanism and impacts of these events. The dataset contains the model output for the following events: 1) 14 January 2008, 10:00 UTC 2) 31 October 2010, 06:00 UTC 3) 30 October 2021, 06:00 UTC

Fig. 2 in The need for transboundary faunistics and conservation: first record of the Natterjack Toad (Epidalea calamita) in Czech Silesia, northeastern Czech Republic

Fig. 2. Newly discovered locality of the Natterjack Toad (Epidalea calamita) in Krnov, Czech Silesia, Czech Republic. The distribution site is located within the Cvilín demolition waste dump, which used to be a sand quarry. (A) The site is now completely filled-up by demolition waste, an unfavorable condition for several species of amphibians present at the site. (B) Puddles are formed in small depressions after the movement of heavy-weight vehicles. However, the formation of such small puddles will probably stop in the near future as the waste dump is now closed. This is another unfavorable condition for this population, together with the surrounding grounds being overgrown by dense vegetation.

Fig. 1. Distribution range of the Natterjack Toad (Epidalea calamita) according to the IUCN Red List of Threatened Species (Beja et al. 2009), updated for the Czech Republic (inset). Red dots show all recent confirmed records (1997–2016; Šandera et al. 2017), demonstrating the very scattered distribution in the Czech Republic. The question mark denotes the region where the Natterjack Toad had occurred before 1990, but has since disappeared (AOPK ČR 2019; Jeřábková and Zavadil 2020). The green star shows the newly discovered population in Krnov, Czech Silesia.
