Data Matrix for Phylogenetic Analysis of Enantiornithes including RAM 14306

Data matrix in TNT format, used to infer the phylogenetic position of RAM 14306 (Raymond M. Alf Museum of Paleontology, Claremont, California) within Aves (as published in Farke &amp; Patel, in press). RAM 14306 is the coracoid of an enantiornithine bird from the Campanian-aged Kaiparowits Formation of southern Utah, USA. The data within the matrix were taken from matrices published by Ji et al. (2011) and O'Connor et al. (2009), with codings for RAM 14306 added by Farke. Character descriptions are provided by O'Connor et al. (2009) and references therein. <strong>Citations</strong> Farke, A. A., and P. P. Patel. In press. An enantiornithine bird from the Campanian Kaiparowits Formation of Utah, USA.
