Neohelos
''Neohelos'' is an extinct diprotodontid marsupial, that lived from the early to middle-Miocene. There are four species assigned to this genus, ''N. tirarensis'', the type species, ''N. stirtoni'', ''N. solus'' and ''N. davidridei''. ''N. davidridei'' is the most derived species of the genus, and its premolar morphology shows that it is structurally and ancestor of the genus ''Kolopsis''. All four species are from the Bullock Creek in the Northern Territory and Riversleigh of Australia. ==Description==
''Neohelos'' is known from many specimens, assigned to all the species. ''N. tirarensis'' includes a partial skull, premaxillas, maxillas, teeth, and dentarys; ''N. solus'' is known from a maxilla and dentary; ''N. davidridei'' includes teeth and a maxilla fragment; and ''N. stirtoni'' is known from a mostly complete skull, a maxilla and a dentary.〔
