By using a non-invasive electron beam, SEM creates images of both high resolution and high magnification at the same time. These analyses provide detailed information about morphology, microstructure or elemental composition of samples.
For over 70 years, the Roman Kozłowski Institute of Paleobiology has been conducting in-depth studies of the history of life on Earth. Every year, the Institute publishes dozens of peer-reviewed articles, organizes conferences, foreign expeditions and excavations in new paleontological sites. We educate PhD students, publish the best paleontological journal in Poland (Acta Palaeontologica Polonica) and popularize science. The staff and laboratories are open to cooperation with other research centers and interdisciplinary projects. An essential part of our Institute is the Paleontological Collection, gathering the largest fossil collections in Poland (hundreds of thousands of specimens), partly exhibited in the Museum of Evolution.
New, very sensitive methods allowed analysing seasonal changes of strontium isotopes in woolly mammoth teeth, thus enabling analysis with under 10-day resolution over more than 10 years of tooth growth.
Throughout their long evolutionary history, crinoids developed pseudoplanktonic lifestyles and attached themselves with long stalks to driftwood. This article describes the microstructure and internal morphology of the stalks of such crinoids from the genus Seirocrinus.
Seas in the Jurassic were much different from now. They were dominated by cephalopods related to squids and cuttlefish. Fish were much less abundant and diversified. Based on Jurassic otolith and statolith assemblages of Poland, Lithuania and the United Kingdom (and published data) we have reconstructed the structure of nekton community and the evolution of actinopterygians.
Lithistids, an informal grouping of demosponges, are sponges with skeletons built of articulated spicules. Typically they are found in deep waters, but off the Somali coast we discovered six species inhabiting sandy sea-bottom at a depth of 50 metres.
Ichthyosaurs are one of the symbols of the Mesozoic and, alongside whales, the best-adapted to a marine lifestyle amniotes. The Lower Jurassic Posidonia Shale abounds in excellently preserved fossils, including ichthyosaurs. We present a specimen of Stenopterygius quadriscissus (Bad Boll, Baden-Württemberg, Germany) from the collection of the Jagiellonian University in Cracow.
