DESCRIPTION OF THE GROUP
Research Group of Evolutionary Geochronology represents the Department of Paleobiology and Evolution at the Faculty of Biology.
Group members carry out research on the evolution of different groups of organisms, partly on the basis of fossil materials, and partly using experimental data for comparison of physiology and anatomy with modern specimens of the studied groups.
Professor Jerzy Dzik
THE LEADER OF THE GROUP
Professor Jerzy Dzik D.Sc. is the author of articles published, among others, in Nature, Geology and Paleobiology, text-books on palaeobiology, zoology, biology and geology. He completed postdoctoral fellowships in Uppsala, Columbus, Ohio, Tübingen and Southampton. He participated in oceanological research in Antarctica, organized scientific expeditions to Siberia, China, and Kazakhstan, and supervised excavations in Upper Silesia. He lectured in Łódź, Sosnowiec and at the Faculties of Geology and Biology of the University of Warsaw. He has promoted six PhDs and many Masters of Sciences. He is the director of the Institute of Palaeobiology of the Polish Academy of Sciences

The activities of the Evolutionary Geochronology Research Group cover various aspects of evolution reconstructed on the basis of the fossil record. The model objects of palaeobiological research on evolution are conodonts — extinct chordates similar to small lampreys. Thanks to the clear daily incre-ments of their teeth visible in the scanning electron microscope, it is possible to calibrate their individual development in days and follow its evolution at population level over millions of years. The second area of research, mainly using computer tomography, is the evolution of the skeleton and biogeographical links between Cretaceous dinosaurs in the Gobi Des-ert and primitive lizards. At the same time, the most ancient animals are being studied in order to recon-struct their anatomy and to determine the links with presentday forms on the basis of materials from Podolia, Siberia and China.
