Analysis of Tooth and Body Size Relationship in Phinopithecus

From the analysis between tooth and body size in Rhinopithecus some aspects were shown,in males there are higher correlation coefficients both in linear or area versus cranial length than in females.On M/D direction,the higher positive allometry,being significantly bigger than females,exist in males.In the maxilla both male and female show stronger correlation with the cranial length than they do in the mandible.The extensive incisal prior to mastication are not necessary for th foods,and the large body size have relatively larger canine with a proportional molar size and dental arch area.Maxillar dental crown area or dental arch area gives a better estimate of maximus grinding space.In Rhinopithecus the relationship between the dentition and body size is closer to Gorilla,Colobus,and Macaca,then to Pan and Homo.
