 Other distinguishing features of the false potto are in the dentition . Sarmiento notes , however , that captive specimens may develop abnormalities in the teeth and that some dental characters Schwartz uses are quite variable , sometimes even from one side of the same individual to another . The third upper molar ( M3 ) is more reduced in the false potto than in any other prosimian , according to Schwartz , but Leon notes that western pottos also have a relatively small M3 . The third upper premolar ( P3 ) is also reduced , resembling the condition in the fork @-@ marked lemurs ( Phaner ) . Stump writes that small <unk> are also common in western pottos , although the false potto 's P3 is shaped differently . Groves notes that P1 is quite long , another point of similarity with the fork @-@ marked lemurs . The lower premolars are compressed laterally in Pseudopotto , the cusps on the cheekteeth are higher , and the cristid obliqua ( a crest connected to the protoconid cusp ) is at a relatively buccal position ( in the direction of the cheeks ) .
