Ostracod crustaceans are the most abundant fossil arthropods. The Silurian
Pauline avibella gen. et sp. nov., from the Herefordshire Lagersta¨tte, UK, is an
extremely rare Palaeozoic example with soft-part preservation. Based on its
soft-part morphology, especially the exceptionally preserved limbs and presence
of lateral eyes, it is assigned to the myodocopid myodocopes. The
ostracod is very large, with an epipod on the fifth limb pair, as well as gills
implying the presence of a heart and an integrated respiratory–circulatory
system as in living cylindroleberidid myodocopids. Features of its shell
morphology, however, recall halocyprid myodocopes and palaeocopes, encouraging
caution in classifying ostracods based on the carapace alone and
querying the interpretation of their shell-based fossil record, especially for the
Palaeozoic, where some 500 genera are presently assigned to the Palaeocopida.
