List of taxa and characters used in phylogenetic analysis.

<p>Save for the addition of <i>Heleocola piceanus</i> and revised scores for characters 4, 74, and 76 for <i>Glasbius twitchelli</i> based upon description of new fossils of this species [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0310948#pone.0310948.ref047" target="_blank">47</a>], we did not modify the list of taxa, characters, or the scores for the taxa from Eberle et al. [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0310948#pone.0310948.ref043" target="_blank">43</a>] who, in turn, incorporated Alaskan metatherian <i>Unnuakomys hutchisoni</i> into the taxon-character matrix of Williamson et al. [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0310948#pone.0310948.ref002" target="_blank">2</a>] and modified these authors’ Character 26. Note: Williamson et al. [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0310948#pone.0310948.ref002" target="_blank">2</a>] use the postcanine dental homologies hypothesized by O’Leary et al. [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0310948#pone.0310948.ref038" target="_blank">38</a>] in their character descriptions and identify the first tooth in the molar series in Metatheria as homologous to the DP5/dp5 of Eutheria.</p> <p>(PDF)</p>
