Wabulacinus
''Wabulacinus ridei'' lived during the early Miocene in Riversleigh. It is named after David Ride, who made the first revision of thylacinid fossils. The material was found in system C of the Camel Spurtum assembledge. ''W. ridei'' was a carnivorous, quadrupedal marsupial in Australia. In appearance it resembled a dog with a long snout. Its molar teeth were specialized for carnivory; the cups and crest were reduced or elongated to give the molars a cutting blade. ''W. ridei'' is known from a right maxillary fragment (QMF 16851) containing molars one and two to the anterior section of the infraorbital foramen that was dorsal to the third molar. The left dentary fragment (QMF 16852) contains a partial second premolar and a full third molar. Premolar 3 and molars one and two are missing with the alveolus intact, no material remains after molar three. Muirhead (1997 p. 372) describes ''W. ridei'' as having the following features that are unique: parametacrista on the first ...

Ngamalacinus
''Ngamalacinus timmulvaneyi'' lived during the early Miocene and has been found in Riversleigh. The species was a carnivorous, quadrupedal marsupial in Australia. In appearance it resembled a dog with a long snout. Its molar teeth were specialized for carnivory, the cups and crest were reduced or elongated to give the molars a cutting blade. Taxonomy The description of a new species and genus was published in 1997, emerging from examination undertaken by Jeanette Muirhead on specimens obtained at the Riversleigh World Heritage Area. The genus combines the Wanyi ''ngamala'', "died out", and the Ancient Greek ''kynos'', alluding to a "dog" for the resemblance to the canid family. The specific epithet names Tim Mulvaney, who was gifted the honour by his aunt, Margaret Beavis, for long time support toward research of Riversleigh fauna. Description A species assigned to a monotypic genus of Thylacinidae, most closely resembling the genus '' Wabulacinus'' yet separable from a ' ...

Thylacinidae
Thylacinidae is an extinct family of carnivorous, superficially dog-like marsupials from the order Dasyuromorphia. The only species to survive into modern times was the thylacine (''Thylacinus cynocephalus''), which became extinct in 1936. The consensus on placement of the family is with the Dasyuromorphia order, with agreement on the divergence this family and the Dasyuridae, represented by the extant quolls and Tasmanian devil ''Sarcophilus harrisii'', remaining under consideration. The thylacinid family was represented by two species in a synonymy published in 1982, the recently extinct Tasmanian tiger and the species '' Thylacinus potens'', known by fossil material. Discoveries of new material, especially in well researched fossil depositions at the Riversleigh World Heritage Area, revealed a diverse array of genera and families existing during Miocene epoch. The dentition of specimens and some largely complete crania showed the development of specialist predators capable ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dentary
In anatomy, the mandible, lower jaw or jawbone is the largest, strongest and lowest bone in the human facial skeleton. It forms the lower jaw and holds the lower teeth in place. The mandible sits beneath the maxilla. It is the only movable bone of the skull (discounting the ossicles of the middle ear). It is connected to the temporal bones by the temporomandibular joints. The bone is formed in the fetus from a fusion of the left and right mandibular prominences, and the point where these sides join, the mandibular symphysis, is still visible as a faint ridge in the midline. Like other symphyses in the body, this is a midline articulation where the bones are joined by fibrocartilage, but this articulation fuses together in early childhood.Illustrated Anatomy of the Head and Neck, Fehrenbach and Herring, Elsevier, 2012, p. 59 The word "mandible" derives from the Latin word ''mandibula'', "jawbone" (literally "one used for chewing"), from '' mandere'' "to chew" and ''-bula'' (i ...

Mutpuracinus
''Mutpuracinus archibaldi'' is an extinct carnivorous, quadrupedal marsupial that lived during the middle Miocene and is the smallest known thylacinid at approximately 1.1 kilograms, the size of a quoll, though, more closely related to the recently extinct thylacine The thylacine ( , or , also ) (''Thylacinus cynocephalus'') is an extinct carnivorous marsupial that was native to the Australian mainland and the islands of Tasmania and New Guinea. The last known live animal was captured in 1930 in Tasma .... ''M. archibaldi'' would have resembled a dog with a long snout. Its molar teeth were specialized for carnivory, the cups and crest were reduced or elongated to give the molars a cutting blade. Fossils of ''M. archibaldi'' have been discovered in deposits at Bullock Creek (Northern Territory) in the Northern Territory of Australia, and in the same deposits as '' Nimbacinus richi''. It is named in honor of Ian Archibald for his contributions to the northern territory ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muribacinus
''Muribacinus gadiyuli'' lived during the middle Miocene in Riversleigh. The species name comes from Wanyi aboriginal word for "little", in reference to its considerably small size compared to the modern thylacine and was similar in size to a fox-terrier dog, and "father" for the ancestral characteristics of the fossilised teeth. ''M. gadiyuli'' was a quadrupedal marsupial predator, that in appearance looked similar to a dog with a long snout. Its molar teeth were specialized for carnivory; the cups and crest were reduced or elongated to give the molars a cutting blade. The holotype and only specimens are a well preserved right maxilla, right dentary, and the holotype, a section of the jugal bone. Taxonomy The description by Stephen Wroe was published in 1995, the author deriving the specific epithet from a Wanyi word ''gadiyuli'', meaning "little"; the Wanyi people are associated with the type location at Riversleigh. The new species was assigned to a new genus of Thylacini ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maximucinus
''Maximucinus muirheadae'' is the largest known thylacinid species that lived in Queensland, Australia from the late Oligocene to the middle Miocene. The species was a quadrupedal marsupial predator, that in appearance looked similar to a dog with a long snout. Its molar teeth were specialized for carnivory; the cups and crest were reduced or elongated to give the molars a cutting blade. It is estimated to have weighed about 18 kilograms. The holotype and only specimen is a second upper molar found in Riversleigh. The species is named after Jeanette Muirhead because of her work on thylacinids. Taxonomy The description was published in 2001 as a new species and genus, recognising greater diversity within the thylacinid family. The author, palaeontologist Stephen W. Wroe, was one of several researchers who discovered over ten new fossil species of thylacinids, mostly from new material extracted from sites at the Riversleigh World Heritage Area Riversleigh World Heritage Ar ...

Badjcinus
''Badjcinus turnbulli'' is an extinct Thylacinidae, thylacinid marsupial.Muirhead and Wroe, 1998. Phylogeny, Phylogenetic analysis shows that thylacines are a clade which does not include the dasyurids. ''Badjcinus'' was one of the most primitive members of its group, living 23 to 28 million years ago in the late Oligocene. The generic name combines the Wanyi Aboriginal Australians, Aboriginal language "badj", 'expert hunter', and a word from Ancient Greek "kynos", meaning 'dog', from which the Thylacinidae name was originally derived. The specific epithet was proposed by the authors to honour the contributions of William D. Turnbull to palaeontology. ''Badjcinus'' was quite small, averaging in weight. It was a carnivore, probably eating small vertebrates and insects, as living ''Dasyurus'' species do today. The fossils were found at Australian Fossil Mammal Sites (Riversleigh), Riversleigh in north-west Queensland, Australia. Since other animals at Riversleigh were rainforest ...

Australian Fossil Mammal Sites (Riversleigh)
Riversleigh World Heritage Area is Australia's most famous fossil location, recognised for the series of well preserved fossils deposited from the Late Oligocene to more recent geological periods. The fossiliferous limestone system is located near the Gregory River in the north-west of Queensland, an environment that was once a very wet rainforest that became more arid as the Gondwanan land masses separated and the Australian continent moved north. The approximately area has fossil remains of ancient mammals, birds, and reptiles of the Oligocene and Miocene ages, many of which were discovered and are only known from the Riversleigh area; the species that have occurred there are known as the Riversleigh fauna. The fossils at Riversleigh are unusual because they are found in soft freshwater limestone which has not been compacted. This means the animal remains retain their three-dimensional structure, rather than being partially crushed like in most fossil sites. The area is ...
