functional analysis of jaw suspension in elasmobranchs
This may simply be a function of upper jaw length. In connecting the jaws to the cranium the hyomandibula must become longer as the upper jaw is lengthened. As the upper jaw becomes longer, the distal end of the hyomandibula is positioned more posteriorly thereby increasing the angle measured. In all five elasmobranchs the jaws extend ...
