A new look at Machaeracanthus
Original language description
Machaeracanthus is a genus based on a few diagnostically significant characters which are useful in separating species. The cross-sectional shape of the spines has been the main character used to diagnose the different species, but this shape varies along the length of the spine and has often been inaccurately estimated. Machaeracanthus spines differ from the ?normal? fin spines of acanthodians and chondrichthyans in that the central canal is totally enclosed, rather than opening out along the proximalend of the trailing edge. A re-examination of specimens indicates that Machaeracanthus had ?paired pairs? of pectoral spines and a distinctive perichondrally ossified scapulocoracoid resembling those of ischnacanthiform acanthodians.
