It is apparent that, on perusing scientific literature concerning Triassic echinoderm fauna from the Germanic Basin, the majority of described species (mainly holotypes) are held in German museums (e.g.: HAGDORN 1995, 1999; HAGDORN, GLUCHOWSKI & BOCZAROWSKI 1996; SALAMON 2003). Only a few specimens are deposited in other countries, including Poland (see: LEFELD 1958; GLUCHOWSKI 1986; GLUCHOWSKI & BOCZAROWSKI 1987; HAGDORN, GLUCHOWSKI & BOCZAROWSKI 1996). A search of the crinoid collection of the Geological Museum of Wroclaw University for specimens of Dadocrinus revealed, apart from dozens of larger fragments of calyxes, several complete forms of the genus (all from Silesian Muschelkalk: MGUWr 861s - 863s, 959s, 963s, 965s, 966s, 968s, 4456s). Accepted curatorial procedure meant that original inscriptions accompanied crinoid specimens lodged in the collection. It was this practice that facilitated the discovery of a specimen of KUNISCH, which had been illustrated by him in 1883 (p. 195, Pl. 8, Fig. 1), and previously described as Dadocrinus gracilis (BUCH, 1845), being the holotype of Dadocrinus kunischi WACHSMUTH & SPRINGER, 1886 (now deposited under no. 959s).
