Dorsal braincase (4 characters) 



123) shape of fronto-parietal suture: 0 = flat; 1 = unilobe; 2 = bi-lobed; 3 = tri-lobed or greater. 

 *124) separate temporal ridges: 0 = widely spaced; 1 = approximately in midline; 9 = absent. 

 *125) sagittal crest: 0 = absent; 1 = present. 



126) size of sagittal crest: 0 = absent, but separate temporal ridges present; 1 = small; 2 = medium; 

 3 = large; 9 = absent. 



Teeth (23 characters) 



127) number of upper incisors in one-half of jaw: 0 = zero; 1 = one; 2 = two; 3 = three. 



128) number of lower incisors in one-half of jaw: 0 = zero; 1 = one; 2 = two; 3 = three. 



*129) morphology of incisors: 0 = peg-like; 1 = unicuspate; 2 = caniform; 3 = complex; 9 = absent. 



130) shape of upper incisors in cross-section: 0 = round; 1 = intermediate; 2 = (strongly) laterally 

 compressed; 9 = absent. 



131) relative size of upper incisors: 0 = outermost incisor about equal in size to remaining incisor(s); 

 1 = outermost incisor of much greater size than remaining incisor(s); 9 = n/a - only one upper incisor 

 present per quadrant. 



132) relative size of lower incisors: 0 = outermost incisor about equal in size to remaining incisor(s); 

 1 = outermost incisor of much greater size than remaining incisor(s); 9 = n/a - one or fewer lower 

 incisors present per quadrant. 



133) displacement of incisors (upper or lower): 0 = absent - all in line with one another; 1 = present 



- incisor series slanted; 9 = n/a - incisors absent or singular. 



134) procumbency of incisors (upper or lower): 0 = absent; 1 = present; 9 = n/a - upper or lower 

 incisors absent. 



135) number of upper postcanines: 0 = three; 1 = four; 2 = five; 3 = six. 



136) number of lower postcanines: 0 = three; 1 = four; 2 = five; 3 = six; 4 = seven. 



137) morphology of postcanines: 0 = peg-like / unicuspate; 1 = triconodont; 2 = multicuspate. 



138) tendency to form additional cusps in triconodont postcanines: 0 = absent; 1 = present; 9 = n/a 



- postcanines not triconodont. 



139) tendency to lose accessory cusps in triconodont postcanines: 0 = absent; 1 = present; 9 = n/a - 

 postcanines not triconodont. 



140) size of accessory cusps in triconodont or multicuspate postcanines: 0 = small, continuous with 

 major cusp; 1 = larger, distinct from major cusp; 9 = n/a - postcanines not triconodont or multicuspate. 



141) relative size of upper postcanines: 0 = all subequal; 1 = #1 (PM 1 ) noticeably smaller than rest, 

 which are subequal; 2 = #5 (M 1 ) noticeably smaller than rest, which are subequal; 3 = #1 and #5 

 noticeably smaller than rest, which are subequal; 4 = #1 and/or #5 noticeably larger than rest, which 

 are subequal; 9 = n/a - postcanine homology uncertain. 



142) relative size of lower postcanines: 0 = all subequal; 1 = #1 (PM,) noticeably smaller than rest, 

 which are subequal; 2 = #5 (M,) noticeably smaller than rest, which are subequal; 3 = #1 and #5 

 noticeably smaller than rest, which are subequal; 4 = #1 and/or #5 noticeably larger than rest, which 

 are subequal; 9 = n/a - postcanine homology uncertain. 



143) tendency to single-rooting of upper postcanines: 0 = absent; 1 = present. 



144) tendency to single-rooting of lower postcanines: 0 = absent; 1 = present. 



145) relative size of gap between upper postcanines 4 and 5: 0 = smaller than other gaps; 1 = subequal 

 to other gaps; 2 = larger than other gaps; 9 = n/a - postcanine homology uncertain.
