..., such study of shale-preserved material is scarcely feasible – and the various forms are assigned to the Bradoriida or Phosphatocopida on the basis of their gross morphology. However, Klausmuelleria salopiensis, more recently described from Shropshire, has soft parts preserved and is important in resolving...

... the Cambrian to Early Ordovician Bradoriida. Evidence from soft-part anatomy indicates that phosphatocopids, the other group hypothesized to be ancestral ostracods, have apomorphies that preclude them as direct ancestors. The origin of ostracods is more likely to be found within the Bradoriida, a probable...

These Indian specimens cannot be distinguished statistically from other A. australis material based on valve length and height ratios, and differ only slightly in other characters. These observations justify the synonymy of a number of similar forms worldwide that previously...

..., the Bradoriida are best regarded as stem group crustaceans ( Shu et al., 1999 ). Bradoriids are considered to have been ecologically diverse and may have occupied a broad range of habitats from epibenthic to possibly nektobenthic or pelagic ( Shu et al., 1999 ). They may have occupied similar ecological...
