Paroodectes feisti (Springhorn 1980, Middle Eocene) was described as a miacid member. Here it is the largest non-sabertooth member of the 'marsupial' sabertooth clade. Smaller members are shown below.

Gustafsonia cognitus (Tomiya and Tseng 2016) formerly Miacis cognitus (Gustafson 1986, Middle Eocene to Early Oligocene). Anterior post-canine teeth were decreasing in size and number. The molars and canines were small. Close to Hapalodectes IVPP V5235 and Paroodectes at the base of the 'marsupial sabertooth' clade. The zygomatic is restored here based on elements now adhering to the mid-ventral skull.

Hapalodectes hetangensis  (Ting and Li 1987; 4.5cm skull length; Paleocene, 55 mya; IVPP V 5235) This skull was originally considered a mesonychid, but here nests with the marsupial clade leading to sabertooth taxa with a shrinking premaxilla. Note the encircled orbits rotated anteriorly as in Thylacosmilus, convergent with primates.
