Stalked crinoid fossils found in Eocene Popiele Beds of Poland's Outer Carpathians

Fossilized remains of stalked crinoids have been discovered in the Eocene Popiele Beds in Poland. These rare echinoderms, including isocrinids and bourgueticrinids, were found in mudstone matrix, suggesting rapid burial in a shallow, nutrient-rich marine environment. The discovery offers new insights into the palaeoenvironmental preferences and ecological persistence of stalked crinoids during the Palaeogene period.
