In the Physeteridae most of the ribs are connected to the vertebrae by both capitula and tubercula. |
The ribs have capitula and tubercula, and sternal and abdominal ribs occur. |
The ribs have capitula and tubercula, and often uncinate processes as in birds. |
The first nine to eleven have the capitula and tubercula separate, afterwards they gradually merge together. |
The capitula are scarcely developed, and the attachment of the tubercula to the transverse processes is loose. |
Its transverse processes and centrum bear facets for the tubercula and capitula of the ribs respectively. |
