Prioniodus navis LINDSTROM, 1955.

Opis

Diagnosis. - The sp elements with a weakly denticulated or adenticulated anterior process , ne elements with weakly denticulated external process.

Remarks. - The relationship between Baltoniodus and Prioniodus still requires clarification. It is generally believed that these genera, characterized by denticulated elements , derived independently from adenticulate species of Acodus (VANWAMEL, 1974), which has been convincingly documented
in the case of Prioniodus (STOUGE and BAGNOLl 1988) but the supposed transition to Baltoniodus has
not yet been described in detail. Another possibility still remains; that the Baltoniodus line age appeared
in the Baltic region as an effect of migration from an unknown area after the transition from early Prioniodus to Baltoniodus had taken place . This is suggested by a rather complex migration pattern in the early evolution of Prioniodus as shown by STOUGE and BAGNOLl ( 1988). Generally the Baltoniodus lineage was cold-water and its range seems to be wider in the "Mediterranean" than North Atlantic realm (DZIK 1984 ).
Late species of Baltoniodus can have a lobate platform, which makes them similar to the balognathids but their anterior process is never ramified .
