FIG. 13 in Craniodental Morphology And Phylogeny Of Marsupials

FIG. 13. Occlusal views of right deciduous third upper premolars (dP3) of Dromiciops gliroides (A, FMNH 127415), Sminthopsis crassicaudata (B, AMNH 196686), and Echymipera kalubu (C, AMNH 221654). Alternative states of character 120 (see main text for description of this character and character states) are illustrated as follows: Dromiciops 120(0); Sminthopsis 120(1); Echymipera: 120(2). Note the obvious wear facet on the postmetacrista of dP3 in S. crassicaudata, indicating that this tooth is occlusally functional.
