Differences between anterior and posterior Ph I
The differences are particularly clear on the illustrated pair of phalanges (BO 89482, HP 35) and on most first phalanges of E. hemionus.
– In the same animal, first anterior phalanges are almost always longer.
– On the posterior Ph I, the distal supra-articular tuberosities are closer to the proximal extremity.
– On the anterior Ph I, the trigonum phalangis reaches farther down (posterior view).
