Fig. 3 in Rostral reconstruction of South American hippidiform equids: New anatomical and ecomorphological inferences

Fig. 3. Anatomical depiction of the rostral musculature of extant horse Equus caballus Linnaeus, 1758. Skull (A), deeper rostral musculature (B), and rostral muscles associated with the mobility of the upper lip (C). Note that B excludes the m. levator nasolabialis, so as not to obscure the m. levator labii superioris.
