The systematics of most Králův Dvůr trilobites are updated based on known museum collections, resulting in no new species or genera and a reduction of earlier described species. The Rawtheyan age of the assemblage is clear, as is its demise at the top of the formation. The upper carbonate unit correlates well with other similar age units from Spain to the Gasp., and it is interpreted as a cool water deposit. Over half the genera are known from earlier in the Barrandian and interchange with Scandinavia, Britain and the rest of Gondwana was considerable during deposition of most of the formation.
