  Although few nondental features of the osteocranium consistently discriminate marsupials from placentals, the transverse canal foramen (TCF) has been repeatedly offered as a potential synapomorphy of crown-group Marsupialia and their closest allies. To explore this contention appropriately, the TCF needs to be evaluated in relation to the morphofunctional complex of which it is a part, something never previously undertaken in a systematic fashion…

  In 1933 George G. Simpson described a remarkably complete skull of Trigonostylops, an Eocene South American native ungulate (SANU) whose relationships were, in his mind, quite uncertain. Although some authorities, such as Florentino Ameghino and William B. Scott, thought that a case could be made for regarding Trigonostylops as an astrapothere, Simpson took a different position, emphasizing what would now be regarded as autapomorphies. He pointed…
