Abstract
Based on three-dimensional models of the skull and body of Paramblypterus duvernoyi, function of the feeding apparatus and potential of locomotion are interpreted. Compared to most other lower actinopterygians, certain modified features regarding the suspensory apparatus, snout bones, gape, dermohyal and suborbital region, and palaloquadrate-maxillary chamber, are present in P. duvernyoi. These features suggest an increased versatility of the skull and/or enlargement of underlying muscles, thus improving the ability of food uptake. The weak, pin-like teeth present in P. duvernoyi suggest a main diet of small or soft-bodied planktonic or benthic invertebrate organisms. Axial locomotion of P. duvernoyi appears to lie within the range of moderate swimming speeds. P. duvernoyi probably had a flat belly indicating that this species lived close to the bottom.

Anhand drei-dimensionaler Modelle des Schädels und Körpers von Paramblypterus duvernoyi werden Funktionsweise des Ernährungsapparates und Möglichkeiten der Fortbewegung interpretiert. Im Vergleich mit anderen basalen Actinopterygiern erscheint die Schädelrekonstruktion von P. duvernoyi hinsichtlich des Suspensoriums. der Schnauzenknochen, der Mundöffnung, des Dermohyal- und Suborbitalbereiches, sowie der Palatoquadratum-Maxillare-Kammer abgeleitet. Dies deutet auf eine erhöhte Beweglichkeit in diesen Bereichen und/oder eine Vergrößerung der darunter liegenden Muskeln hin, was vorteilhaft für die Nahrungsaufnahme ist. Die schmalen, stiftförmigen Zähne von P. duvernoyi deuten auf eine Ernährung von kleineren oder weichkörperigen benthischen und planktischen Invertebraten hin. Vermutlich zeichnete sich die axiale Fortbewegungsweise von Paramblypterus durch mäßige mittlere Schwimmgeschwindigkeit aus. Der Bauch von P. duvernoyi war wahrscheinlich abgeflacht, was darauf hinweist, dass diese Art bodenbezogen gelebt hat.
