In 2010, Brian Blake Andres wrote a review of pterosaur phylogeny in his dissertation. His phylogenetic analysis combined data mainly from three different matrixes: Kellner's original analysis (2003) and its updates (Kellner (2004), Wang et al. (2005) and Wang et al. (2009)), Unwin's original analysis (2003) and its updates (Unwin (2002), Unwin (2004), Lu et al. (2008) and Lu et al. (2009)) and previous analyses by Andres et al. (2005), Andres and Ji (2008) and Andres et al. (2010). Additional characters are taken from DallaVecchia (2009), Bennett' analyses (1993-1994) and various older, non-phylogenetic, papers.
The matrix includes 100 valid pterosaur species plus a single outgroup (Euparkeria capensis). This represents 70.4% of 142 known pterosaur species. These were scored for 183 morphological characters (compared to 3 outgroups plus 57 ingroups which were scored for 89 characters of Wang et al. 2009 [the latest version of Kellner's analysis] and to 1 outgroups plus 59 ingroups which were scored for 117 characters of Lu et al. 2012 [the latest version of Unwin's analysis]). The resultant topology is well suppoted and more resolved than previous analyses. Furthermore, it codes only species as terminal taxa, (unlike some analyses, e.g., Unwin (2003) who used mainly families) and uses the holotype specimens for the codings (unlike some analyses, e.g., Kellner (2003)). This phylogenetic analysis was used by Richard J. Butler, Stephen L. Brusatte, Brian B. Andres and Roger B. J. Benson (2012) to assess the morphological diversity and fossil sampling biases of the Pterosauria. A paper focusing on the pterosaur phylogeny (Andres, in press) will be published in an upcoming book named "The Pterosauria". An updated and more resolved version of this phylogeny was published formally by Andres and Myers (2013) containing 185 characters and 109 ingroup taxa. Below is a cladogram showing these results after the exclusion of three taxa that can be coded only for one character (clade names follow Andres & Myers, 2013).
