A palaeosomatid millipede, associated with plant material and trigonotarbid arthropods, is reported from the Carboniferous (Namurian A) of Silesia. The millipede is similar to congeneric specimens previously described from the Westphalian A of England. Palaeosomatids, contrary to previous reports, are not spinous, but do share a number of characters with spinous archipolypods. The occurrence of congeneric forms of Palaeosoma in Silesia and England provide further evidence of the broad distribution of millipede genera in the Euroamerican tropics during the Carboniferous. The new family Palaeosomatidae and new order Palaeosomatida are proposed to include the single genus Palaeosoma.

Permian millipedes are rare, especially so considering the relative abundance of millipedes in Carboniferous rocks. We report an early Permian millipede fauna containing three new genera and species of millipedes (Oklahomasoma richardsspurense new genus new species, Karstiulus fortsillensis new genus new species, and Dolesea subtila new genus new species) found in fossil-producing pockets of the Fort Sill fissures exposed in the Dolese Quarry near Richards Spur, southwest Oklahoma, USA. These are the first new genera of invertebrates to be described from this site, one of the most prolific fossil-vertebrate sites in the world. We also comment on taxa with morphological similarities and note previously described occurrences of Permian millipedes as well as occurrences of fossil myriapods (millipedes and centipedes) in karst deposits (caves and fissure fills) in Europe, Africa, Asia, North America, and the Caribbean. In contrast with the forms found at Richards Spur, most of these previous accounts of millipedes found in caves and fissure fills are of Pleistocene forms that are closely allied to modern taxa. The taxa from Richards Spur bear some similarities to Pennsylvanian forms. Karst (cave and fissure) faunas should be ranked with concretion faunas, cannel coals, and amber faunas as a major source of fossil myriapods.
