Lestodontini

PP = 100, age = 7.06 Mya (5.32–9.16).

The clade is composed of Lestodon and Bolivartherium and was recovered in all analyses.

Lestodontini was supported by 11 synapomorphies (six for both methods and five exclusively for BI): presence of a well-developed diastema between Cf1/cf1 and molariforms; Cf1 closer to anterior edge of maxilla than to Mf1; Cf1/cf1 displaced laterally relative to molariform toothrow; anteroposteriorly ovate mf1 cross-section (BI); anteroposteriorly ovate mf2 crosssection (BI); maximum length of nasal bones greater than or equal to three times the width of both nasals (BI); attachment of the base of jugal to skull dorsal to Mf2 (BI); well-developed buccinator fossa of maxilla, with a deep depression; absence of a crest at median suture of palatine; dorsally situated infraorbital canal; and posteroventrally inclined occipital condyle in lateral view (BI).
