Turnovichthys magnus ŠTAMBERG, 2001

Specimens MHK 82592 and MHK82601 represent terminal fragments of large spines. The fragments of the spines carry conspicuous, longitudinally arranged ribs that converge towards the tip of the spine (Pl. 1, Fig. 3). The spine wall is formed by trabecular dentine. The finds of these large spines suggest the presence of a large sphenacanthid elasmobranch in the Ploužnice lake as previously demonstrated by Štamberg (2001) with the Turnovichthys magnus spine from the Ploužnice Horizon in the locality Krsmol. Additionally, typical sphenacanthid placoid scales (Pl. 1, Fig. 5) and tooth fragments were found .
