Kurzfassung
Die Diagnose der fossilen NeoselachiergattungPalaeospinax Egerton 1872 wird verbessert. Aus dem Posidonienschiefer (Unter-Toarcium) von Süddeutschland wird eine neue Art dieser Haie alsPalaeospinax politus n. sp. beschrieben. Sie unterscheidet sich von alien anderen bekanntenPalaeospinax-Arten durch den Besitz von glatten, nicht ornamentierten vorderen und lateralen Zähnen.
Abstract
The diagnosis of the fossil neoselachian genusPalaeospinax Egerton 1872 is revised. A new species from the Lower ToarcianPosidonia Shale of Southern Germany is described asPalaeospinax politus n. sp. It differs from all other known members of the genus in having smooth anterior and lateral teeth.
