“…This is not unsurprising, given that Mythunga was also recovered from the upper Albian Toolebuc Formation, whereas Ferrodraco is from the Cenomanian–lowermost Turonian Winton Formation, also from the Eromanga Basin. A close relationship between Ferrodraco and Mythunga has been supported in various phylogenetic analyses 11 , 12 , 16 , 23 , 25 , 26 . Moreover, these results support the interpretation of an anhanguerian radiation in the Australian Cretaceous, coinciding with the marine transgression in the Eromanga Basin, noted by Richards, et al 23 .…”

“…Haliskia can be distinguished from KK F600, based on the alveolar configuration, wherein the first four alveoli are spaced close together in the latter. Although KK F600 was referred to T. shawi by Richards, et al 26 , we question this referral based on the lack of anatomical overlap between the holotype and referred specimen, the presence of at least three pterosaur taxa in the Toolebuc Formation and the taxonomic diversity of anhanguerians in other localities, such as the Araripe Basin 8 .

“…Although most of the Australian pterosaur material derives from the Toolebuc Formation of Queensland 17 – 24 , all specimens reported from this unit to date are isolated and fragmentary. These include indeterminate anhanguerians 17 , 18 , 20 , 21 , 24 , as well as three of the four named Australian pterosaur taxa: the anhanguerians Mythunga camara 19 , 25 and Thapunngaka shawi 23 , 26 , and the targaryendraconian Aussiedraco molnari 22 , 27 . Phylogenetic analyses have clarified the affinities of all three named taxa, with a close relationship between Mythunga and Ferrodraco supported in several phylogenetic analyses 11 , 12 .…”

“…Phylogenetic analyses have clarified the affinities of all three named taxa, with a close relationship between Mythunga and Ferrodraco supported in several phylogenetic analyses 11 , 12 . These are sometimes resolved in a polytomy with either Tropeognathus mesembrinus 12 , 16 or Thapunngaka shawi 23 , 26 , and the latter result led to the erection of the clade Mythungini 26 . Despite these advances, the precise phylogenetic position of the Australian anhanguerians remains unclear, as does the true diversity of pterodactyloids from the Cretaceous of northeast Australia.…”
Pterosaur remains have been reported from every continent; however, pterosaur skeletons remain rare. A new pterosaur is presented here, Haliskia peterseni gen. et sp. nov., constituting the most complete specimen from Australia from the upper Albian Toolebuc Formation of the Eromanga Basin (Queensland, Australia). A combination of features, including the presence of a premaxillary crest and curved teeth, and the morphology of the scapulocoracoid, support its referral to Anhangueria. Haliskia can be distinguished from all other anhanguerian pterosaurs based on two dental characters: the 4th and 5th tooth pairs are smaller than the 3rd and 6th, and the 2nd and 5th alveoli are smaller than 3–4 and 6–8. Moreover, the hyoid is 70% the total length of the mandible. The phylogenetic analyses presented here place Haliskia within Anhangueria. In one analysis, Haliskia and Ferrodraco are resolved as sister taxa, with Tropeognathus mesembrinus sister to that clade. The other resolves Haliskia, Mythunga and Ferrodraco in a polytomy within Tropeognathinae. The new Australian pterosaur attests to the success of Anhangueria during the latest Early Cretaceous and suggests that the Australian forms were more taxonomically diverse and palaeobiogeographically complex than previously recognized.
