Diagnosis
ReferenceDiagnosis
R. H. Tedford et al. 2009Rami distinguished from those of X. dubius Teilhard de Chardin, 1940, by larger average size; premolars not as elongate, wider, and higher crowned; p2 lacks posterior cusp; second posterior cusp on p4 smaller, often closely appressed to cingulum; m2 with metaconid smaller relative to proto- conid and narrower talonid.
