The Tympanum A depressor mandibuli muscle originating from the prominent ridge on the squamosal just medial of the groove housing the external auditory meatus and inserted on the process of the articular would allow ample room for a tympanum with a diameter of about 30 mm. The tympanum having one point of attachment on the free tip of the lip of the ledge bounding the stapedial recess could lie in a parasagittal plane and receive the tympanic process of the stapes meeting it at right angles. The external auditory meatus extending from the tympanum along the groove in the posterior face of the squamosal could have its opening just above the level of the upper limit of the squamosal ridge. The nature of the joint of the stapes with the quadrate as described above would allow of movement of sufficient amplitude for the conduction of sound Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original South African Museum.
