Notes on development of the Oligocene trachinid Trachinus minutus (Jonet, 1958)
Original language description
The fossil trachinid species Trachinus minutus (Jonet, 1958) from the Paratethys area is represented by numerous specimens, but none of them is larger than ca. 35 mm. Newly collected material from the Hermanowa locality allows a better interpretation of the morphological changes that occur during ontogeny to be described from a size of about 10 mm to the largest preserved stage. These changes are connected with the origin and changes in the morphology of selected skull bones, the origin of fins and the number of fin rays. In general, it is possible to say that the smallest preserved specimen shows a well-developed skull roof, otic part, angulo-articular, dentary, maxillae, anterior part of the premaxillae, preopercles, cleithra, first four spines of the first dorsal fin, and ventral fin spines. The ethmoid, together with the ectopterygoid, opercles and corpus quadrati are more or less recognizable, but obviously in the initial stages of their morphogenesis. There are about 22 vertebrae preserved in the vertebral column, with decreasing visibility further posteriorly (the caudal portion of the column was probably not ossified sufficiently and therefore is not recognizable). Other elements are not yet developed or distinctive. During later stages of ontogeny, the ossification of the skull and postcranial skeleton continue, the fifth spine of the first dorsal fin appears, and the anal and second dorsal fins start to form. The morphology of some bones changed rapidly during ontogeny and their appearance is conditional on the particular age of the specimen. These data are compared with our knowledge of Recent trachinids.
