Vertebrate Paleobiology

Research topics

Our research group studies the evolution of vertebrates, based on the fossil record. Our main focus is the comparative anatomy of the skeletal system, used to reconstruct anatomical function, which helps us understand the lifestyle of fossil organisms, as well as evolutionary trajectories (phylogenetics). In addition, our topics include: paleoneurology, organism decay and fossilization (taphonomy), and paleoenvironmental reconstructions. We are interested in the study of several vertebrate groups, primarily: lizards, dinosaurs, conodonts, ray-finned fish, lungfish, and primates. We lead regular excavations in various paleontological sites across Poland, covering a broad geological time range (mainly Devonian, Permian, Triassic, and Miocene).

Methods

Mechanical and chemical preparation of fossils, scanning electron microscopy, computed tomography, electromagnetic and density separation of sediment, differential staining of tissues, Dental Topographic Analysis, phylogenetic analysis.
