Abstract
-
The Clupeomorpha are a diverse, widespread group of fishes containing about 317 Recent and about 100 known fossil species. They are known as far back as the Cretaceous, and today are worldwide in distribution. Surprisingly little is known about this group phylogenetically. This study briefly reviews past work on clupeomorph interrelationships and examines the skeletal morphology of clupeomorphs to produce materials for a revision of the subgroups of clupeiform fishes. By concentrating on clupeomorph osteology, fossils can be added to the resulting classification.;It was found that several skeletal characters define groups such as Clupeomorpha, Clupeomorpha Division 2, Clupeiformes, Clupeoidei, and some clupeoid subgroups. Based on osteological characters, the family Pristigasteridae should be excluded from the superfamily Clupeoidea (which includes Chirocentridae and Clupeidae); and the groups Pristigasteroidea, Engrauloidea, Clupeoidea, Clupeidae, Pellonulinae and Dussumieriinae were each found to be monophyletic. Cladograms for Pristigasteroidea, Dussumieriinae and Pellonulinae based on osteological characters are also given.;No osteological characters were discovered to indicate that Dorosomatinae, Alosinae, Clupeinae, or these three groups together, are monophyletic. The biggest remaining problem in clupeomorph systematics is seen as discovering the interrelationships of the members of these three subfamilial "groups of convenience" among Clupeoidei.;Skeletal preparation of over 750 clupeomorph specimens representing 92 genera (82 Recent) and 155 species (140 Recent) were examined here for the character information above and for several other morphological and meristic features (such as number of predorsal bones, branchiostegal rays, etc) summarized in part by tables 1a to 10a and 1b to 10b. The osteology of a pellonuline (Odaxothrissa vittata) and a dorosomatine (Dorosoma cepedianum) is also descriptively illustrated in detail.;It is hoped that this work will serve as a base for future phylogenetic studies on clupeomorph fishes by paleoichthyologists and Recent ichthyologists interested in clupeomorph osteology. The interrelationships of clupeid fishes, and the placement of many fossil species within Clupeomorpha are still under study.
