| Abstract [eng] |
The as sem blage of rare fish microremains of chon dri chthyans and actinopterygians from Up per Perm ian de pos its in KarpÅnai Quarry in north ern Lith u a nia is de scribed in de tail for the first time. The de pos its are char ac ter ized as re flect ing a rapid phase of de po si tion of the Zechstein Lime stone, in ter preted as on a shal low shelf above storm-wave base in a prox i mal part of the Pol ish-Lith u a nian Zechstein Ba sin. The actinopterygian microremains are rep re sented by var i ous teeth and a few scales from mostly palaeonisciforms and pycnodontiforms. The chondrichthyans are rep re sented by var i ous eusela - chian-type scales and a tooth of ?Helodus sp. The low abun dance and low spe cies di ver sity of the fos sil as sem blages stud - ied may be due to arid palaeoenvironments that caused lo cally re stricted con di tions at this palaeo geo graphi cal lo ca tion. |
