The eotitanosuchian bite was stronger and more efficient than the biarmosuchian bite. For this reason, some paleontologists see the eotitanosuchids as transitional between the biarmosuchians and higher <a href="/wiki/Therapsid" class="mw-redirect" title="Therapsid">therapsids</a>. It is at least as likely that features of a larger temporal opening—and hence increased <a href="/wiki/Muscle_mass" class="mw-redirect" title="Muscle mass">muscle mass</a> and <a href="/wiki/Biting" title="Biting">biting</a> power—evolved simultaneously among a number of early therapsid groups, due to the obvious advantages this adaptation conferred. One must be wary in applying <a href="/wiki/Cladistic" class="mw-redirect" title="Cladistic">cladistic</a> methodology to characteristics that are likely to evolve simultaneously among many competing lineages. In other respects the eotitanosuchians are quite primitive; they were the least modified in their <a href="/wiki/Jaw" title="Jaw">jaw</a> apparatus from their <a href="/wiki/Sphenacodont"
