Accessed May 14, 2008. ref Silvabestius is an extinct genus of marsupial dating to the Early Miocene. They were grazing animals about the size of a modern sheep. This is proven as the skull size was about 25cm long. The Silvabestius is 1m long in length. The Silvabestius was a herbivore which browsed on soft plant matter such as leaves and stems. Silvabestius lived in an environment that largely consisted of tropical rainforests. The Silvabestius has close living relatives that exist now such as koalas and wombats which are found in Australia. The Silvabestius is in the extinct family called the Diprotodontidae and is therefore closely related to the giant marsupial Diprotodon. Two well preserved fossils were found belonging to a Silvabestius these fossils were 2 skulls believed to be a mother and child, These skulls were found in Riversleigh Queensland, Australia. The two skulls were found extremely close together. The baby believed to of been in the mothers pouch when they died. The fossil is referred to Madonna and child.

The Alcoota Fossil Beds are an important paleontological site located on Alcoota Station in Central Australia , 200km north east of Alice Springs . It is notable for the occurrence of well preserved, rare, Tertiary vertebrate fossils, which provide evidence of the evolution of the Northern Territory s fauna and climate. The Alcoota Fossil Beds are also significant as a research and teaching site for palaeontology students. The Alcoota deposit is a series of intermittently interconnected lakes within a large basin. Evidence suggests that the concentration of fossils is due to a phenomenon called waterhole tethering During dry periods, animals concentrated in the intermediate area of the continually shrinking spring fed lake, resulting in the death of many animals. The Alcoota and Bullock Creek fossil faunas provide evidence that aridification was in progress in northern Australia during the mid Miocene geological time period. History The Alcoota Fossil Beds are one of only three known vertebrate fossil sites in the Northern Territory, along with Bullock Creek and the Kangaroo Well site. Although locals had known about the existence of fossils at Alcoota for a long time, it was not until 1962 that the first serious studies were conducted. Further excavations were conducted sporadically until 1984, when the Museum and Art Gallery of the Northern Territory commenced an annual excavation program. In 1988 a permanent field station was erected on site and the valuable Alcoota Beds were fenced in order to provide them with some protection. The Alcoota fauna is about 8 million years old and has a rich concentration of vertebrate fossils. This makes it especially interesting as it lies between the older faunas of Kutjamarpu Southern Australia and Bullock Creek Northern Territory and the younger deposits of Riversleigh Queensland and Beaumaris, Victoria Beaumaris Victoria . Because of its intermediate age, remote ancestors of the well studied Australian megafauna as well as of ... more details

The three genera may have diverged at an earlier date, although the drying of the continent and the expansion of Eucalyptus forests towards the late Miocene may have delayed the evolution of cranial features unique to the modern genera. This indicates that either fossil genera could be an ancestor of the modern genus, or the modern genus has a common ancestor to both. More material needs collection to improve their taxonomical relationships. The genus lived about 10&ndash 16 million years ago in the middle Miocene Riversleigh of Queensland. This area is described as a rainforest habitat at time of sediment Deposition geology deposition . It had a different diet to the modern species, with the dental symphysis unfused, indicating a diet that was properly varied in nature, unlike the specialised nature of Phascolarctos . The size is estimated to be only half of the modern genus. Cranial adaptations are intermediate between the extant common brushtail possum and koala, with minor divergence from either. This genus and Nimiokoala are similar in most anatomical features so far as is known, except that Litokoala possessed superficial messateric process while Nimiokoala had more marked basio wikt occipital occipital basi Sphenoid bone sphenoid flexion and a more extensive posterior attachment of the Pterygoid bone pterygoid Louys et al., 2009, p. 989 , which make these features basal in their taxonomical position in relation to the Phascolarctos . The basiocranial back of skull features are similar to Phascolarctos , while anterior ... more details
refimprove date June 2010 Taxobox fossil range Fossil range Early Miocene status ex status system iucn3.1 status ref regnum Animal ia phylum Chordate Chordata classis Mammal ia infraclassis Marsupialia ordo Dasyuromorphia familia Thylacinidae genus Wabulacinus species W. ridei binomial Wabulacinus ridei 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 tooth 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 Dental alveolus alveolus intact, mo material remains after molar three. Muirhead 1997 p. 372 describes W. ridei as having the following features that are unique para meta crista on the first molar is straight, entoconid either missing of combined with the hypoconid in a more posterior position, the loss or reduction of styler crests , small metaconid , talon id basin reduced by the lingual toward the tongue placement of the hypoconid. Dasyurid type features include the infraorbital foramen away from the jugal and a large hypoconid. Only one feature of the tooth links this species to Ngamalacinus timmulvaneyi Ngamalacinus , and that is the metaconid and protoconid are reduced. Features that are in common with the Thylacinus genus are the centrocrista is straight on the first upper molar, the angle of the crest at the paracone and metacone is wider than plesiomorphic thylacinida ... more details
