The BYU specimens attributed to 
Mesadactylus 
nest with anurognathids like ?Dimorphodon weintraubi (coeval and also from North America) in the large pterosaur tree (LPT). The specimen is Late Jurassic (Morrison Formation) in age.

Sprague and McLain 2018 conclude, “the taxonomic affinity of the genus is uncertain.” So why did they title their talk “Resolving…”

All they had to do
was Google “Mesadactylus.” Or run a phylogenetic analysis. The affinities of this specimen have been known here at the LPT since 2012.
