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) was published in a book named "The Pterosauria". An updated and more resolved version of this phylogeny was published formally by Andres and Timothy Myers in 2013, containing 185 characters and 109 ingroup taxa.
