M a t e r i a l: NMPc02887a, b, Pc 02888; collected in the Subchert Mb.

R e m a r k s: The species is represented by isolated dentary and a disarticulated skeleton at the locality. Although the dentary is crushed, it is possible to recognize its low elongated shape with typical dentition: small teeth alternate with large teeth (their tips are marked by white arrows in text-fig. 2B). The disarticulated skeleton consists of only 15 vertebrae (others are not preserved) and a strongly disarticulated head and pectoral girdle bones. The specimen was determined on the basis of morphology of the cleithrum, the postcleithrum, and organization of the caudal skeleton. Other morphological data are not sufficiently preserved. The species was found at the Moravian localities Bohuslavice, Kelč, Špičky, Horní Těšice, Mouchnice, Litenčice, Nikolčice, Nosislav, Židlochovice, Křepice, Rožnov pod Radhoštěm, and Loučka ( Kalabis 1948, 1975a, b, Kalabis and Schultz 1974, Gregorová 1988, 1989, 2011, Přikryl et al. 2012 and unpublished data).

The species was characterized as mesopelagic or bathypelagic ( Prokofiev 2005b or Jerzmańska 1968 respectively), similar to the recent genus Gonostoma .
