Relaciones entre la longitud prearticular y la longitud estándar en los peces Pycnodontiformes

Abstract

Pycnodontiform fishes are a well-known group, represented in many conservation Lagerstätten worldwide. They occur from the Late Triassic to the Eocene, and some genera were distributed worldwide. Much work has been done during the last centuries, but most scientists studied the taxonomy. The palaeobiology of the Pycnodontiformes has been rarely the central question in their publications. This paper presents a method to reconstruct the standard length by the means of the prearticular length. The main result is a positive correlation between the prearticular length and the standard length, that it is possible to reconstruct the standard length of Gyrodus and Proscinetes from Lower-Saxony (NW-Germany) and the Solnhofen area (S-Germany) for paleobiological studies.
