Kunbarrasaurus ieversi
Taxonomy
Kunbarrasaurus ieversi was named by Leahey et al. (2015). Its type specimen is QM F18101, a skeleton (a near-complete ankylosaurian dinosaur specimen that includes most of the skull and mandible, along with an articulated postcranium), and it is a 3D body fossil. Its type locality is Marathon Station, Flinders River (QM), which is in an Albian basinal (carbonate) lime mudstone in the Toolebuc Formation of Australia.

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| L. G. Leahey et al. 2015 | The cranial roof is flat (excluding some very slight arching of the postorbital and nasal); the dorsal surfaces of the prefrontal, supraorbital and postorbital elements form an approximately 90° angle with the lateral surfaces of the skull; the supraorbital comprises a single element; the prefrontal is restricted to the dorsal surface of the skull and does not contribute to the orbit; the nasals do not contribute to the lateral surface of the skull, being restricted to the dorsal surface and the medially displaced nasal vestibule; the nasal vestibule (which is completely formed by the nasal bone) is large in proportion to the maxillary rostrum, fully exposed dorsally and laterally; the maxilla extends for the entire dorsoventral height of the skull and contacts the cranial roof at the prefrontal; the caudal end of the tooth row terminates ventral to the caudal margin of the orbit; the lacrimal is vertically (dorsoventrally) orientated; the pterygoids do not contact one another caudally near the braincase and are completely separated by the basisphenoid; the long axis of the quadrate is vertically aligned; the coronoid process is very pronounced; the sidewall of the braincase is poorly ossified, such that many of the cranial nerves must have traversed large bony apertures rather than the discrete foramina; the inner ear is extremely large in proportion to the skull and morphologically unlike any other known dinosaur in that the vestibular region is not separated by bone from the endocranial cavity, the ventral cochlear region is poorly ossified, and the vestibular region is so expanded that the semicircular canals appear very short; cranial dermal ossifications are either flat or with a very shallow keel; no quadratojugal and squamosal horn or boss-like dermal ossifications are present. |
