erected the name Euctenochasmatia instead of Pterodactylidae for his conclusion. Unwin had considered Euctenochasmatia to be a subgroup within Ctenochasmatoidea, similar to his former conclusion of Pterodactylidae, but most analyses have since found the genus Pterodactylus to be more primitive than previously thought, making the clade Euctenochasmatia the more inclusive group containing both Pterodactylus and Ctenochasmatoidea. Below is cladogram following a topology recovered by Brian Andres, using the most recent iteration of his data set (Andres, 2021). Andres' analysis found Pterodactylus to be a close relative of the ctenochasmatoids. Earlier, in 2017, Steven Vidovic and David Martill had recovered a significantly different set of relationships for early pterodactyloids. They placed Pterodactylus outside Euctenochasmatia, as the sister taxon of the more inclusive group Lophocratia. References Pterodactyloids
