Abstract
Phosphatized cybelinid trilobite larvae in an exceptional state of preservation have been obtained from early Ordovician limestones in northern Spitsbergen. A stage below the anaprotaspis is described, and termed the phaselus stage. There is a case for regarding the phaselus larva as homologous with the nauplius larva of extant Crustacea.
