“…As was hypothesized for the Frasnian phyllocarids from the Gogo formation of Western Australia, the cuticle of these arthropods may have been enriched in calcium carbonate (Briggs et al . ). Thus, the phosphatic composition of the cuticle seen in the Kowala specimens is most likely to be the result of early diagenetic phosphatization during taphonomical processes (see Zatoń et al .…”

Phyllocarida (Crustacea, Malacostraca) are among the most diversified and widespread Late Devonian arthropods. Although previous studies mention phyllocarid fossils from Late Devonian (Frasnian and Famennian) deposits of the Holy Cross Mountains of south‐central Poland, phyllocarids from the Kowala quarry have not been systematically described. Two new species are described from Kowala strata: Echinocaris bisulcata sp. nov. characterized by oval carapace valves with a short hinge line, cone‐like tubercules on the carapace anterior lobe, two pronounced lateral sulci (ventral and median) and two pairs of short spines on every abdominal segment; and Montecaris marynowskii sp. nov. characterized by two pairs of robust abdominal spines, a telson that is shorter than furcal rami, distal parts of which are parallel to the telson, and a body length approximately four times longer than the telson length. Additionally, an isolated furca identified as Dithyrocaris sp. is described herein. Damage observed in the holotype specimen of Montecaris marynowski sp. nov. is consistent with a healed injury, possibly caused by predatory fish. Notes concerning the global occurrences of montecaridids, echinocaridids and the genus Dithyrocaris in the Late Devonian are also provided.

Nahecaris balssi Broili, 1930 is a phyllocarid crustacean known only from the Lower Devonian Hunsrück Slate in Germany. This study redescribes the species on the basis of 22 new specimens and the holotype. Phylogenetic analysis of several Palaeozoic phyllocarids reveals that N. balssi and N. stuertzi Jaeckel, 1921 are not congeneric, as was previously assumed, and that there are significant morphological differences between these taxa. Thus, the new genus Oryctocaris is erected for N. balssi, characterized mainly by the absence of a rostrum and a median dorsal plate. It is suggested that O. balssi was a fairly active swimmer, which was not limited to the benthic zone. Furthermore, the species presumably swam by means of powerful pleopod strokes coupled with downward movements of the abdomen. It is likely the telson spine with its furcal rami acted as a paddle, enhancing propulsion. We suggest that O. balssi was a deposit feeder, foraging by digging in the mud and picking up food particles or small hard-shelled organisms such as molluscs, which were then crushed by the large and robust mandibles.http://zoobank.org/urn:lsid:zoobank.org:pub:7A84A8A9-F9F3-464E-A3B2-24B9056EE0B6

We describe a new archaeostracan phyllocarid from the famous Early Devonian Hunsr€ uck Slate, Germany. Morphological features suggest a new ceratiocaridid species for which we propose the name Ceratiocaris harpago sp. nov. The exceptionally well-preserved holotype specimen is the most completely known ceratiocaridid with an almost entire set of appendages including biflagellate antenniform antennules, robust uniramous antennae with hook-like flagellum, thoracopods densely covered with setae and probably six pairs of pleopods. A nectobenthic lifestyle is considered the most probable and the clasper-like morphology of the antennae suggests the presence of a sexual dimorphism in this taxon, with the holotype specimen being a male individual.
