Die Bauchschuppen vonMoythomasia nitida Gross (Pisces, Actinopterygii)

Abstract

In einem Versuch, die Orientierung der Bauchschuppen-Schragreihen bei dem devonischen PalaeoniscoidenMoythomasia nitida zu klaren, werden drei verwendbare Exemplare dieser Form des Actinopterygiermaterials aus dem Plattenkalk der Paffrather Mulde angefuhrt. Bei diesen ziehen samtliche Bauchschuppenreihen zwischen Brustflossen und Analflosse nach antero-medial. Entlang der ventralen Medianlinie trennt eine unregelmasige longitudinale Reihe relativ kleiner Schuppen die rechten und linken Bauchschuppenreihen. Letztere bilden dorso-lateral einen deutlichen Winkel mit den Schuppen-Schragreihen der Korperseiten. In der vermutlichen Position eines ursprunglichen ventro-lateralen Flossensaums sind die Schuppenreihen der Bauchregion und der Korperseiten durch eine unregelmasige longitudinale, schrag nach postero-ventro-medial ziehende Reihe von Inversionsschuppen getrennt. Eine ahnliche Orientierung der Bauchschuppenreihen wie beiM. nitida ist unter den Palaeoniscoiden nur beiOsorioichthys marginis und den Haplolepiformes beobachtet worden, wahrend, die Mehrzahl postero-medial in Verlangerung der Korperseiten-Schragreihen ziehende Bauchschuppenreihen besitzt. Eine Berucksichtigung der Verhaltnisse in dieser Hinsicht bei dem heutigenLepisosteus osseus dem rezenten BrachiopterygierPolypterus bichir und zwei devonischen Osteolepidenexemplaren (ein Exemplar zuGyroptychius groenlandicus gehorend) zeigt, das die Schuppen-Schragreihen der Bauchregion und besonders der vorderen Ventralregion eine unterschiedliche Orientierung und Ausbildung bei den Teleostomen haben. Vorerst konnen diese Gegebenheiten nicht taxonomisch verwendet werden.
