is rarely collected, probably because itis nocturnal, fossorial, and semiaquatic (Harrisson,1962; Manthey and Grossman, 1997). Few specimensexist in collections worldwide, and skeletons are ex-tremely rare. As a result of limited access to speci-mens, many phylogenetic analyses that include thisspecies relied upon the same specimen (REE 1445, col-lection of Richard Etheridge, San Diego State Univer-sity) to score osteological characters (e.g., Pregill et al.,1986; Estes et al., 1988; Norell and Gao, 1997; Gao andNorell, 1998).This problem is not unique to
