ResumoespanolLos peces Pycnodontiformes son un grupo muy conocido, presente en numerosas colecciones de todo el mundo. Se les conoce entre el Triasico Superior y el Eoceno, y algunos generos tienen una amplia distribucion a escala mundial. Han sido muy estudiados en los dos ultimos siglos, pero la mayoria de los trabajos tratan sobre taxonomia, siendo raros los que versan sobre paleobiologia. En este articulo se presenta un metodo que relaciona la longitud estandar con la longitud prearticular. El principal resultado es una correlacion positiva para los generos Gyrodus y Proscinetes de la Baja Sajonia (NO de Alemania) y de la zona de Solnhofen (S de Alemania), para futuros estudios paleobiologicos. EnglishPycnodontiform fishes are a well-known group, represented in many conservation Lagerstatten 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.
