During the last years, feeding mechanisms of sharks have been documented mainly based on their stomach contents supplemented by video footages of feeding behaviours in some species. Rare kinematic analyses of shark jaws contributed additionally to ou

Most pycnodontiform fishes are represented by their distinctive dentition alone, whereas articulated skeletons are very rare and the systematic position of most taxa based upon isolated teeth and the association of upper and lower dentitions to a spe

The functional morphology of the jaw apparatus and the skull and the feeding habits of the extinct pycnodont fishes are reconstructed in comparison with some extant halecostomes. For this a short review of the functional units of the pycnodont head i
