Gunggamarandu

Gunggamarandu (meaning "river boss" in Barunggam and Wakka Wakka) is an extinct monospecific genus of tomistomine crocodilian from Pliocene-Pleistocene aged deposits in the Darling Downs (possibly the Riversleigh lagerstätte) of Australia. Gunggamarandu represents the first tomistomine known from Oceania and it is also the southernmost known tomistomine to date. The type, and only known, species is Gunggamarandu maunala (meaning "head hole", after the Barunggam words for such), which was described by Jorgo Ristevski et al. in 2021.

In 1995, Salisbury et al. suggested that QMF14.548 may have been a gavialoid. QMF14.548 was formally described in 2021 by Jorgo Ristevski et al. and it was named Gunggamarandu maunala. It was found in a layer of rock in the Darling Downs in Australia, which dates to the Pliocene-Pleistocene ages, sometime around 5–2 million years ago. The western Darling Downs is predominantly Pliocene, while the rest is mainly Pleistocene, but since it is unknown exactly where in the Darling Downs the holotype of Gunggamarandu was discovered, its exact age is unknown.
