What is "mekosuchus"

Mekosuchus is a genus of extinct Australasian crocodiles within the subfamily Mekosuchinae. They are believed to have been made extinct by the arrival of man on the South Pacific islands where they lived. The species of this genus were small in size, 2 m in maximum length, and terrestrial, making them the last surviving group of fully terrestrial crocodilians, leaving only semi-terrestrial species such as the Cuban crocodile and the dwarves Osteolaemus and Paleosuchus.

Fossils of related mekosuchines, such as Trilophosuchus, have been found from Miocene Australia (the earliest known mekosuchine is the Eocene genus Kambara), though the mekosuchines had gone extinct in Australia prior to the arrival of humans. Mekosuchus survived until the Holocene, and their sub-fossils have been found in New Caledonia and Vanuatu.
