FIG. 8. Postpalatal region of Caluromys philander (A, AMNH 267002), Dromiciops gliroides (B, UWBM 78641), Dactylonax palpator (C, AMNH 191042), and Potorous tridactylus (D, AMNH 66168). Alternative states for characters 43 and 45–50 (see main text for descriptions of these characters and character states) are illustrated as follows: Caluromys 43(0), 45(0), 46(0), 47(1; but note that C. philander is polymorphic for this character), 48(0), 49(0), 50(0); Dromiciops 43(1), 45(1), 46(3), 47(0), 48(1), 49(0), 50(0); Dactylonax 43(1), 45(1), 46(2), 47(1), 48(0), 49(0), 50(1); Potorous 43(-), 45(2), 46(1; but note that the modal condition for P. tridactylus is 0), 47(1), 48(0), 49(1), 50(0). Abbreviations: als, alisphenoid (purple, coossified with basisphenoid); apf, anterior pterygoid foramen; atp, alisphenoid tympanic process; bk, basisphenoid keel; bs, basisphenoid (purple, coossified with alisphenoid); cc, carotid canals; ecr, ectopterygoid crest; fo, foramen ovale; pal, palatine (green); plfp, posterolateral palatal foramen; ps, presphenoid (blue); pt, pterygoid (yellow); ptf, pterygoid fossa; tcf, transverse canal foramen; v, vomer (orange).
