Rhizophascolonus
''Rhizophascolonus'' is an extinct genus of diprotodont known from the Early Miocene of South Australia.Additional specimens of the oldest wombat, ''Rhizophascolonus crowcrofti'' (Vombatidae; Marsupialia) from the Wipajiri Formation, South Australia: an intermediate morphology? J. Vert. Paleo. 28: 1144link/ref> The genus was first described to accommodate a new fossil species of Vombatidae, ''Rhizophascolonus crowcrofti'', in 1967. A discovery at Riversleigh was published as another new species in 2018, ''Rhizophascolonus ngangaba'', and further specimens from this area were assigned to ''R. crowcrofti'' in the same study.

Ruben Arthur Stirton
Ruben Arthur Stirton (1901-1966), known to his friends as "Stirt", was an American Paleontology, paleontologist, specializing in mammals, who was active in South America, the United States and Australia. Stirton was closely associated with the University of California Museum of Paleontology, receiving an appointment as curator in 1930 and as its fourth director from 1949 to 1966. His career also saw engaged as a lecturer, associate professorship and then as a professor in 1951, from which time he was director of the University's Department of Paleontology. Stirton was born in Kansas on 20 August 1901, and graduated from University of Kansas, the state's university in the field of zoology. He served as the mammalogist on expeditions led by Donald R. Dickey to El Salvador in the 1920s. His expeditions included a return to El Salvador in the 1940s, as well as another collecting fossils in Colombia. In 1953, he directed his studies to the marsupials of Australia, with the intent of d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oligocene
The Oligocene ( ) is a geologic epoch of the Paleogene Period and extends from about 33.9 million to 23 million years before the present ( to ). As with other older geologic periods, the rock beds that define the epoch are well identified but the exact dates of the start and end of the epoch are slightly uncertain. The name Oligocene was coined in 1854 by the German paleontologist Heinrich Ernst Beyrich from his studies of marine beds in Belgium and Germany. The name comes from the Ancient Greek (''olígos'', "few") and (''kainós'', "new"), and refers to the sparsity of extant forms of molluscs. The Oligocene is preceded by the Eocene Epoch and is followed by the Miocene Epoch. The Oligocene is the third and final epoch of the Paleogene Period. The Oligocene is often considered an important time of transition, a link between the archaic world of the tropical Eocene and the more modern ecosystems of the Miocene. Major changes during the Oligocene included a global expansion o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miocene
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia.

Diprotodont
Diprotodontia (, from Greek "two forward teeth") is the largest extant order of marsupials, with about 155 species, including the kangaroos, wallabies, possums, koala, wombats, and many others. Extinct diprotodonts include the hippopotamus-sized ''Diprotodon'', and ''Thylacoleo'', the so-called "marsupial lion". Characteristics Living diprotodonts are almost all herbivores, as were most of those that are now extinct. A few insectivorous and omnivorous diprotodonts are known, and the Potoridae are almost unique among vertebrates in being largely fungivorous, but these seem to have arisen as relatively recent adaptations from the mainstream herbivorous lifestyle. The extinct thylacoleonids ("marsupial lions") are the only known group to have exhibited carnivory on a large scale. Diprotodonts are restricted to Australasia. The earliest known fossils date to the late Oligocene, but their genesis certainly lies earlier than this, as large gaps occur in Australia's fossil record, w ...

Riversleigh, Queensland
Riversleigh is a rural locality in the Shire of Murweh, Queensland, Australia. In the , Riversleigh had a population of 16 people. History The locality takes its name from the parish, which in turn took its name from a pastoral station. The name appears on the 1887 Post Master General's map of Queensland. The name of the pastoral station is thought to reflect its situation on Angellala Creek, near its junction with the Warrego River. The locality was officially bounded on 28 March 2002. In the , Riversleigh had a population of 16 people. Road infrastructure The Warrego Highway passes to the north and the Mitchell Highway Mitchell Highway is an outback state highway located in the Central West Queensland, central and South West Queensland, south western regions of Queensland and the North West Slopes, northern and Central West, New South Wales, central western ... to the west.

Prehistoric Vombatiforms
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
