Thapunngaka (meaning "Spear Mouth" in Wanamara) is a genus of anhanguerid pterosaur recovered from the Early Cretaceous marine Toolebuc Formation in Queensland, Australia.

Thapunngaka was initially discovered in June 2011 within the Lower Cretaceous, Upper Albian Toolebuc Formation on Wanamara Country, North West Queensland, Australia by fossicker Mr. Len Shaw.

[2] The type species Thapunngaka shawi was described by Timothy Richards, Paul Stumkat and Steven Salisbury from the Kronosaurus Korner museum.

[1] In its description, Thapunngaka was assigned within the subfamily Tropeognathinae of the family Anhangueridae, sister taxon to both Ferrodraco and Mythunga.

The cladogram below shows a topology published by Richards and colleagues in 2021, which is based on a study by Borja Holgado and Rodrigo Pêgas in 2020:[1][4] Siroccopteryx Tropeognathus Mythunga Ferrodraco Thapunngaka Aerodraco Coloborhynchus Nicorhynchus Uktenadactylus Caulkicephalus Guidraco Ludodactylus Liaoningopterus Cearadactylus Maaradactylus Anhanguera In 2023, Richards et al. published a revised diagnosis of Thapunngaka where they also erected the clade Mythungini.
