dc.description.abstract "Study of adult gill-arch dentition of Recent and some fossil fishes suggested that the condition primitive for gnathostomes included numerous dermal elements, initially small but capable of growth. During evolution these small units apparently were organized into specialized structures of several types, through processes involving fusion between initially separate dermal elements, and in some cases fusion between the dermal skeleton and visceral endoskeleton. Advanced types of gill-arch dentition were found to characterize most of the major groups of fishes. These types, combined with characters of the gill-arch endoskeleton and related muscles, provided a basis for discussion of the phyletic interrelationships of all major fish groups represented in the Recent fauna. Concerning relationships, conclusions reached are in essential agreement with those of earlier workers. In addition, the basic branching of the gnathostomes appears to be consistent with the sister-group model of Hennig. On the basis of this agreement and consistency it was possible to propose a revised higher classification of fishes, proceeding from the assumption that sister-group relationships among Recent organisms must be expressed in the main outlines of a phyletic classification. Because it is generally agreed that tetrapods are related to rhipidistian fishes, it was possible to extend the classification to include the major groups of Recent tetrapods. The final result was a revised higher classification of the superclass Gnathostomata in which the major groups are arranged not arbitrarily but according to their probable phyletic interrelationships"--P. 535. en_US

Files in this item

This item appears in the following Collection(s)

  • Bulletin of the American Museum of Natural History
    The Bulletin, published continuously since 1881, consists of longer monographic volumes in the field of natural sciences relating to zoology, paleontology, and geology. Current numbers are published at irregular intervals. The Bulletin was originally a place to publish short papers, while longer works appeared in the Memoirs. However, in the 1920s, the Memoirs ceased and the Bulletin series began publishing longer papers. A new series, the Novitates , published short papers describing new forms.
