Lipotyphlans, many condylarths, and their descendants often emphasize shearing between the hypoconid and the blades of the centrocrista that Hnk the metacone and paracone, which usually are well separated to their bases. Superimposed labial and lingual oblique views of M2 of UCMP 136091 and M^ of UA 4081 demonstrate that the former has a slightly less bowed ectoflexus and a more robust and absolutely larger metacone and metastylar blade. Slightly greater wear on the metastylar blade of UA 4081 might overemphasize the difference, but we sus- pect that the difference is real, yet within.
