Polychaete jaw apparatuses from the Ordovician and Silurian of Poland and a comparison with modern forms
No abstract. Selected quote from Introduction: "In contrast to the general scarcity of polychaete jaw apparatuses in fossil materials there is a large collection of Ordovician and Silurian polychaete jaw apparatuses assembled recently in the Palaeozoological Institute of the Polish Academy of Sciences in Warsaw. This collection derives from erratic boulders scattered over northern Poland. In 1950 Professor ROMAN KOZLOWSKI, in connection with his studies on graptolites, began to collect these limestones and dissolve them in hydrochloric and acetic acid. In addition to the graptolites and various chitinous microfossils, he obtained a collection of polychaete jaw apparatuses in an excellent state of preservation . KOZLOWSKI (1956) described from this collection three species belonging to the genera Polychaetaspis KOZLOWSKI and Polychaetura KOZLOWSKI. In 1960 Professor KOZLOWSKI put at the writer's disposal the remaining collection of polychaete jaw apparatuses for investigation
