Abstract
The monograph on the 500 million-year-oldRehbachiella from the Upper Cambrian ‘Orsten’ of Sweden, published inFossils & Strata 32 by Walossek (1993) comprises a detailed description of its larval sequence and a discussion of functional and comparative aspects of its morphology and ontogeny. A particular attempt was made to clarify the status of Branchiopoda and the phylogenetic position ofRehbachiella as an early branchiopod with particular respect to structural and functional identity of the postmandibular locomotory and feeding apparatus apomorphic to the Branchiopoda. The data provided byRehbachiella and other ‘Orsten’ fossils also aided examination of the ontogenetic patterns of Crustacea and discussion of the morphology and evolution of Crus- tacea.
