the lenticular process may be homologous to the shaft of the stapes and result from fusion of the former quadrate- stapes articulation. This speculation is consistent with the observation that artiodactyls have a very short lenticular process (Thewissen & Hussain (1993)), with perhaps greater length to the corresponding process of the stapes
