Abstract

The study of sticklebacks has seen a recent resurgence. This group of fishes, though representing only a few taxa, poses a number of difficult problems. Two areas which must be explored in order to understand the Gasterosteidae are their fossil record and osteology. The examination of the Pliocene fossils is interesting in the context of some of the trends seen in modern stickleback populations. A partial survey of the osteology of this family, while seeming to emphasize only the mosaic nature of the interrelations of the Gasterosteidae, does point the way for possible research which may help elucidate the relationships within the family and of the gasterosteids to other teleosts. A new Pliocene species of Gasterosteus is proposed.
