Diagnosis
ReferenceDiagnosis
L. Dingus 1990Michenia deschutensis n. sp. possesses a longer C J - P J diastema, broader P4 with a more distinct mesoconid-entoconid separation, stouter and shorter metacarpal III-IV and metatarsal III-IV, and a shorter more stout proximal phalanx than Michenia agalensis. M. deschutensis n. sp. shows stronger fusion of roots on P ] , larger P4, larger and longer metacarpal III-IV and metatarsal III-IV , stronger fusion of metatarsal III-IV, and a longer more slender proximal phalanx than Michenia exilis.
