Petrodactyle (meaning "stone finger") is an extinct genus of ctenochasmatid pterosaur from the Late Jurassic Mörnsheim Formation (Solnhofen limestone) of Bavaria, Germany.

[1] The holotype and only known specimen, LF 2809, was recovered from the "Dritte Rosa" layer of the Mörnsheim Formation, near Mühlheim in Bavaria, Germany.

[1] In 2023, Hone et al. described Petrodactyle wellnhoferi as a new genus and species of ctenochasmatid pterosaur based on these fossil remains.

[1] In their 2024 description of Skiphosoura, Hone et al. scored Petrodactyle into an extensively modified version of the phylogenetic dataset of Pêgas (2024).

[4] As was initially speculated by Hone and colleagues in 2023, Petrodactyle was recovered as closely affiliated with gallodactylid taxa such as Normannognathus and Cycnorhamphus.
