BaruBaru is an extinct genus of Australian mekosuchine crocodilian. It's fossils have been found from various Late Oligocene and Miocene localities from across the Northern Territory and Queensland, indicating that Baru was a common species during the late Paleogene and early Neogene. Two species are currently recognized, B. wickeni and B. darrowi, with a third undescribed species also being known. Baru was a large and powerfull mekosuchine with an incredibly deep and robust skull and long, blade-like teeth that in the case of Baru darrowi are furthermore adorned with minute serrations.
VoliaVolia is an extinct monospecific genus of mekosuchine crocodylian closely related to Mekosuchus and Trilophosuchus. Volia is known from a collection of largely fragmentary remains including skull bones and limbs recovered from the Voli Voli and Wainibuku Caves on Viti Levu (Fiji), with similar remains having been found on Naigani. It was around long, making it the largest predatory animal on the island and subsequently most likely the apex predator of the Pleistocene ecosystems of Fiji.
MekosuchusMekosuchus est un genre éteint de crocodiles d'Australasie au sein de la sous-famille des Mekosuchinae. Leur extinction semble dater de l'arrivée de l'Homme sur les îles d'Océanie. Les espèces de ce genre étaient de petite taille, de longueur maximale et étaient terrestres, ce qui en faisait le dernier groupe de crocodiliens terrestres, alors qu'il ne reste plus aujourd'hui que des espèces semi-terrestres comme le Crocodile de Cuba et les crocodiles nains des genres Osteolaemus et Paleosuchus.
TrilophosuchusTrilophosuchus (« crocodile à trois crêtes ») est un genre éteint de crocodiles de la sous-famille des Mekosuchinae. Il a vécu en Australie, où ses fossiles ont été trouvés à Riversleigh, dans le nord-ouest du Queensland, dans des sédiments datés du Miocène moyen (Langhien et Serravallien), soit il y a environ entre et millions d'années. Une seule espèce a été décrite : l'espèce type, Trilophosuchus rackhami par Paul Willis, de l'Université de Sydney, dans le Journal of Vertebrate Paleontology en 1993.
AustralosuchusAustralosuchus is an extinct monospecific genus of crocodylian belonging to the subfamily Mekosuchinae. The type and only known species Australosuchus clarkae lived during the Late Oligocene and the Early Miocene in the Lake Eyre Basin of South Australia. It was described in 1991 by Paul Willis and Ralph Molnar from fossil material discovered at Lake Palankarinna. Australosuchus is among the mekosuchines with the southernmost distribution, being found exclusively at a latitude below 27°S, which is the basis for its scientific name meaning "southern crocodile".
KambaraKambara is an extinct genus of mekosuchine crocodylian that lived during the Eocene epoch in Australia. It is generally thought to have been a semi-aquatic generalist, living a lifestyle similar to many of today's crocodiles. Four species are currently recognized, the sympatric Kambara murgonensis and Kambara implexidens from sediments near Murgon, the poorly preserved Kambara molnari from the Rundle Formation and the youngest of the four, Kambara taraina, also from the Rundle Formation.
PaludirexPaludirex (meaning "swamp king") is an extinct genus of mekosuchine crocodylians from the Pliocene and Pleistocene of Australia. Remains of this animal have been found in the Riversleigh lagerstätte of northwestern Queensland. It was a medium-sized crocodilian, estimated to grow to at least 4 metres in length. In 1886 Charles Walter De Vis informally described Pallimnarchus pollens based on fragmentary cranomandibular and osteoderm material discovered around 1860 that was mineralised by apatite.
HarpacochampsaHarpacochampsa is a poorly known Early Miocene crocodilian from the Bullock Creek lagerstätte of the Northern Territory, Australia. The current specimen consists of a partial skull and fragments of a long, slender snout reminiscent of that of a false gharial, demonstrating that it was a piscivore in life. It was originally tentatively placed within a group of Australian crocodilians now known as the Mekosuchinae, although this has been frequently disputed, with other authors instead suggesting it may have been a more basal crocodyloid or a type of gavialid.
