RESUMO
In the neurocranium of the domestic fowl the centres of ossification present at hatching and appearing susbequently have been investigated and illustrated. The controversy over centres around the orbit is reviewed and it is concluded that paired laterally placed pleurosphenoids are present by the time of hatching, while paired orbitosphenoids situated near the midline and dorsal to the optic foramen do not appear until between 70 and 91 days after hatching. No additional "presphenoid" centres were detected. The neurocranial articulations were studied: 27, many of them paired, were identified. The sequence and timing of synostosis were determined.
