| Abstract |
Phyllocarids other thanNahecaris stuertzi are rare in the Hunsrück Slate. The few specimens, mostly fragmentary, are here described and referred to seven different taxa:Heroldina rhenana, Ceratiocarina fam. et gen. indet.,Montecaris? sp.,Nahecaris? halssi, Nahecaris sp.,Dithyrocaris? sp., and Rhinocarididae gen. et sp. indet. Almost none of them yields diagnostic characters permitting identification at even generic level. Some may be different body regions of the same taxon. The Hunsrück Slate phyllocarids, includingNahecaris, preserve characters which indicate an affinity with the leptostracan Malacostraca. Schram’s (1986) reassignment of the phyllocarids to the Class Phyllopoda is therefore rejected. |
