Malleodectidae
''Malleodectes'' is an extinct genus of unusual marsupial, first discovered in 2011 at Riversleigh, Queensland, Australia. Taxonomy The description of the new genus and two species, was published in 2011, based on fossilised type material discovered at a Riversleigh site. The type species is named ''Malleodectes mirabilis'' and the second description published as ''Malleodectes moenia''; their generic epithet combines terms derived from the Latin, ''malleo'' meaning hammer, and Ancient Greek, ''dectes'' for biter, in reference to the unusual dentition. ''Malleodectes'' was classified as the sole genus of Malleodectidae in a 2016 revision, with the family allied to Dasyuromorphia. A 2025 study assigned the genus '' Barinya'' and, tentatively, the new genus ''Weirdodectes'' to the family Malleodectidae. Description A marsupial with highly specialised dentition, an enlarged premolar with a flattened profile used to hammer open the shells of snails found in its wet forested ...

Weirdodectes
''Weirdodectes'' is an extinct genus of malleodectid that lived during the Middle Miocene. Distribution ''Weirdodectes napoleoni'' is known from fossils found in Queensland Queensland ( , commonly abbreviated as Qld) is a States and territories of Australia, state in northeastern Australia, and is the second-largest and third-most populous state in Australia. It is bordered by the Northern Territory, South Austr ..., Australia. Etymology The genus name ''Weirdodectes'' derives from the unusual morphology of the first molar, which is unique among marsupials. The species name ''napoleoni'' honours the lead author’s deceased dog, who provided emotional support for them during their studies.

Dasyuromorphia
Dasyuromorphia (, meaning "hairy tail" in Greek) is an order comprising most of the Australian carnivorous marsupials, including quolls, dunnarts, the numbat, the Tasmanian devil, and the extinct thylacine. In Australia, the exceptions include the omnivorous bandicoots (order Peramelemorphia) and the marsupial moles (which are insectivorous but are very different and are now accorded an order of their own, Notoryctemorphia). Numerous South American species of marsupials (orders Didelphimorphia, Paucituberculata, and Microbiotheria) are also carnivorous, as were some extinct members of the order Diprotodontia, including extinct kangaroos (such as '' Ekaltadeta'' and '' Propleopus)'' and thylacoleonids, and some members of the partially extinct clade Metatheria and all members of the extinct superorder Sparassodonta. The order contains four families: one, the Myrmecobiidae, with just a single living species (the numbat), two with only extinct species (including the thylacine ...

Extinction
Extinction is the termination of an organism by the death of its Endling, last member. A taxon may become Functional extinction, functionally extinct before the death of its last member if it loses the capacity to Reproduction, reproduce and recover. As a species' potential Range (biology), range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxon, Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the Fossil, fossil record) after a period of apparent absence. Over five billion species are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryotes globally, possibly many times more if microorganisms are included. Notable extinct animal species include Dinosaur, non-avian dinosaurs, Machairodontinae, saber-toothed cats, and mammoths. Through evolution, species arise through the process of specia ...

Ferret
The ferret (''Mustela furo'') is a small, domesticated species belonging to the family Mustelidae. The ferret is most likely a domesticated form of the wild European polecat (''Mustela putorius''), as evidenced by the ferret's ability to interbreed with European polecats and produce hybrid offspring. Physically, ferrets resemble other mustelids because of their long, slender bodies. Including their tail, the average length of a ferret is about ; they weigh between ; and their fur can be black, brown, white, or a mixture of those colours. The species is sexually dimorphic, with males being considerably larger than females. Ferrets may have been domesticated since ancient times, but there is widespread disagreement because of the sparseness of written accounts and the inconsistency of those which survive. Contemporary scholarship agrees that ferrets were bred for sport, hunting rabbits in a practice known as rabbiting. In North America, the ferret has become an increasingly pro ...

Fossil Taxa Described In 2011
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Though the fossil record is incomplete, numerous studies have demonstrated that there is enough information available to give a good understanding of the pattern of diversification of life on Earth. In addition, the record can predict and fill gaps such as the discovery of ''Tiktaalik'' in the arctic of Canada. Paleontology includes the study of fossils: their age, method of formation, and evolutionary significance. Specimens are sometimes considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years to 4.1 billion years old. Early edition, published online before print. The ob ...

Riversleigh Fauna
Riversleigh fauna is the collective term for any species of animal identified in fossil sites located in the Riversleigh World Heritage Area. Faunal zones The presence of the Riversleigh in the Oligo-Miocene has been exceptionally well preserved throughout a number of time periods. These has been classified by four "faunal zones", and may be summarised as, * Faunal Zone A (FZA): late Oligocene, a period 23.03–28.4 million years before present * Faunal Zone B (FZB): early Miocene, 15.97-23.03 myr * Faunal Zone C (FZC): middle Miocene, 11.608-15.97 myr * Faunal Zone D (FZD): late Miocene, 5.332-11.608 myr More recent fossil specimens has also been coded to the period of deposition, * Pliocene (PLIO), a period 2.588-5.332 myr * Pleistocene (PLEIS), 0.0117-2.588 myr * Holocene, noted as (HOLO) to indicate the period dated as following the Pleistocene, from the present day to 11,700 years ago.

Prehistoric Mammals Of Australia
Prehistory, also called pre-literary history, is the period of human history between the first known use of stone tools by hominins 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 years ago. It took thousands of years for writing systems to be widely adopted, with writing having spread to almost all cultures by the 19th century. The end of prehistory therefore came at different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. It is based on an old conception of history that without written records there could be no history. The most common conception today is that history is based on evidence, however the concept of prehistory hasn't been completely discarded. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miocene Marsupials
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 followed the Oligocene and preceded 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 distinct global events but by regionally defined transitions from the warmer Oligocene to the cooler Pliocene Epoch. During the Early Miocene, Afro-Arabia collided with Eurasia, severing the connection between the Mediterranean and Indian Oceans, and allowing the interchange of fauna between Eurasia and Africa, including the dispersal of proboscideans and hominoids into Eurasia. During the late Miocene, the connections between the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
