Fusions within the mandible of the domestic fowl (Gallus gallus domesticus).
The articulations formed within the mandible of the domestic fowl by its constituent elements have been described and illustrated. The sutures identified were suturae angulosplenialis, angulosupra-angularis, articulare/pre-articulo-angularis, articulare/pre-articulosupra-angularis, dento-angularis, dentosplenialis, dentosupra-angularis and supra-angulosplenialis. Some degree of fusion was found to occur in all sutures except sutura supra-angulosplenialis. The range of fusion time and mean fusion time for each site was studied in a flock of Golden Comet pullets. Mean fusion times varied from 45-119 days post-hatching.
