FIG. 12 in Craniodental Morphology And Phylogeny Of Marsupials

FIG. 12. Occipital views of Lestodelphys halli (A, UWZM 22422), Metachirus nudicaudatus (B, AMNH 267009), and Trichosurus vulpecula (C, AMNH 65557). Alternative states of characters 32, 90, 91, 93, and 95 (see main text for descriptions of these characters and character states) are illustrated as follows: Lestodelphys: 32(0), 90(0), 91(1), 93(1), 95(0); Metachirus: 32(1[but note that the modal condition for M. nudicaudatus is 0]), 90(0), 91(0), 93(2), 95(1); Trichosurus vulpecula: 32(-), 90(1), 91(0), 93(2), 95(0). Abbreviations: exo, exoccipital (yellow, coossified with basioccipital); fm, foramen magnum; mas, mastoid exposure of pars canalicularis of petrosal (blue, coossified with pars cochlearis); mf, mastoid fenestra; par, parietal (purple); pp, paroccipital process (of exoccipital); so, supraoccipital; sq, squamosal (orange). Specimens are not drawn to the same scale.
