Mythunga: a disputed pterosaur name from Australia

Mythunga camara was named for part of a toothed pterosaur skull from marine rocks in Queensland. The fossil consists of jaw pieces rather than a complete head or winged skeleton. A reinterpretation of its broken front end changed the supposed snout length, and a 2025 study argued that the remaining traits do not distinguish a separate genus. The specimen remains significant even if its name is treated as doubtful.

Quick facts

A Queensland fossil in a limestone nodule

Phillip Gilmore found the fossil in April 1991 at Dunluce Station near Hughenden and donated it to the Queensland Museum, where it became QM F18896. Laurie Beirne recognised it as a pterosaur, and Angela Hatch prepared it. Ralph Molnar and Richard Thulborn named Mythunga camara in 2007. The species epithet refers to the chambered interior of its hollow snout.

The specimen came from a calcareous nodule in the marine Toolebuc Formation. Ammonites, other molluscs and scattered ichthyosaur bones were noted in the area. These establish a marine depositional setting, not where the flying animal fed or died. No wing, trunk, leg or complete skull belongs to the holotype.

Why the supposedly short snout changed

The original interpretation treated the preserved portion as most of the anterior skull, implying a relatively short snout. Subsequent workers recognised that its anterior end was missing: the fossil is a middle segment of a longer rostrum. An old short-beaked restoration should therefore not be treated as an observation from the rock.

The jaws bear sizeable conical teeth and locally wavy edges. Early diagnoses used the spacing and relative height of teeth to distinguish the animal. Later comparisons questioned whether these features are unique. Thapunngaka is another Queensland pterosaur known from different jaw material; its fossil cannot simply be attached to the missing front of QM F18896.

From a new genus to a doubtful name

Revisions compared Mythunga with toothed anhanguerians, including tropeognathines. This placement rests on jaw anatomy; no complete skeleton tests it. In 2025, a phylogenetic study argued that the traits proposed as unique to Mythunga are also present in related forms. Its authors called the name a nomen dubium and treated the holotype as an indeterminate tropeognathine. This is a published taxonomic judgement, not a claim that the fossil itself has vanished.

Ferrodraco illustrates how associated postcranial bones can inform the classification of an Australian pterosaur. None is associated with Mythunga. A new specimen would have to be securely linked to the type before it could settle the name's standing.

What living-animal artwork can show

Neither wingspan nor body mass can be measured from the surviving jaw pieces. Their teeth permit discussion of grasping animal prey, but no prey remains identify fish or any other particular food. A coastal setting is consistent with the marine rock, while a specific hunting route is unknowable.

The cover and shoreline scene are artistic reconstructions of an anhanguerian-like pterosaur. Wing outline, full beak, crest, skin and colour remain unverified for QM F18896. Even the continued use of the name Mythunga depends on how future comparisons assess its diagnostic features.
