dc.description.abstract "The strangest features in the arrangement of the head muscles in Protoceratops consist in the orbital location of the pseudotemporalis as in the Psittaci and in the slight muscular covering of the lateral surface of the mandible. In particular, the deep excavation at the ventrolateral face of the dentary and angular requires an explanation. Perhaps this area was filled with a bulky gland, something like an accessory infralabial gland, corresponding to the similar concavity along the upper dental series. Perhaps the peculiar type of dental occlusion caused a ventral shifting of the infralabial gland, whereas the supralabial remained near the upper dental series, as the lateral maxillary excavation seems to indicate. Other peculiarities of the muscular arrangement consist in the differentiation of an accessory adductor externus superficialis, emerging from the jugal-epijugal prominence, and in the possibility of an encroachment of anterior pseudotemporalis fibers craniolaterally of the coronoid elevation"--P. 23. en_US
