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.
Shells of marine gastropods from hydrothermal vent environments are coated with inorganic materials of unknown composition. Conversely, their fossil equivalents are known exclusively from outer moulds in pyrite (FeS2), with no shell material left.
Methane (CH4) is largely built from the light carbon isotope (12C). When emitted from the seabed, methane is oxidized by sediment-dwelling microorganisms, with one of the byproducts being methanogenic carbonate cements, themselves with large amounts of the 12C.
Ammonites, extinct cephalopods dominant in Mesozoic marine ecosystems, are often listed amongst victims of the end-Cretaceous mass extinction (66 Ma). Claims of their local survival across the Cretaceous–Paleogene boundary have faced scepticism from parts of the palaeontological community.
Spirotubus are puzzling microfossils from southern Poland, dating from the Devonian period, around 380 million years ago. The Spirotubus skeletons are tiny calcareous (calcitic) tubes with a spiral pattern on their outer surface.
The article presents an overview of marine environments that existed in the area of present-day Poland around 380–360 million years ago, during the Devonian period, when this region was covered by an extensive shallow and warm sea. This sea was oversaturated with calcium, a component of the common biomineral calcite.
