M.54079(GC87 175 A) (Fig. 21) 



This specimen is a proximal phalanx lacking its proximal end, with 

 a total length of 37.7mm (Fig. 21 ). The side is indeterminate. The 

 proximal end is damaged and the epiphysis is missing. The damage 

 is close to the epiphyseal line (the nutrient foramina are visible) but 

 not enough of the region survives to know whether or not the 



epiphysis was fused. There is a large crack running proximodistally 

 along the palmar surface of the diaphysis, as well as some damage to 

 one side of the shaft at the proximal end. The transverse diameter of 

 the shaft expands gradually from distal to proximal, and in this 

 aspect the specimen most closely resembles that of a proximal 

 phalanx from the third or fourth ray. The crests for attachment of the 

 fibrous sheaths for Mm. flexor dif^itarum profundus and / d. 

 superficialis are well marked and prominent on this specimen.
