Riversleigha
''Riversleigha williamsi'' is a species of hipposiderid bat discovered in fossil deposits located the Riversleigh World Heritage Area in the north of Australia. Taxonomy The description of ''Riversleigha williamsi'' was published in 1998 by Suzanne J. Hand, the author separating the novel species by erecting a new genus, ''Riversleigha''. The type material was obtained at Bitesantennary Site, a rich deposit of previously unknown chiropteran taxa, and the ninth species to be discovered by the researchers at the Riversleigh fossil area from which the genus name is derived. The specific epithet was nominated by the author for Stephan Williams, who had assisted in the processing of large amounts of fossiliferous limestone extracted from the Bitesantennary Site, the species type location. Description ''Riversleigha'' was a large species of hipposiderid Old World leaf-nosed bat. These are found in Europe and other regions of the Old World The "Old World" is a term for Afr ...

Hipposideridae
The Hipposideridae are a family of bats commonly known as the Old World leaf-nosed bats. While it has often been seen as a subfamily, Hipposiderinae, of the family Rhinolophidae, it is now more generally classified as its own family.Simmons, 2005, p. 365 Nevertheless, it is most closely related to Rhinolophidae within the suborder Yinpterochiroptera. Taxonomy The Hipposideridae contain 10 living genera and more than 70 species, mostly in the widespread genus '' Hipposideros''. In addition, several fossil genera are known; the oldest fossils attributed to the family are from the middle Eocene of Europe. In their 1997 ''Classification of Mammals'', Malcolm C. McKenna and Susan K. Bell proposed a division of Hipposideridae (called Rhinonycterinae in their work) into three tribes, one with two subtribes, but these tribes turned out to be non-monophyletic and have been abandoned. A different classification was proposed by Hand and Kirsch in 2003. In 2009, Petr Benda and Peter Val ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Riversleigh World Heritage Area
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 locat ...

Type Locality (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almos ...

Old World
The "Old World" is a term for Afro-Eurasia that originated in Europe , after Europeans became aware of the existence of the Americas. It is used to contrast the continents of Africa, Europe, and Asia, which were previously thought of by their inhabitants as comprising the entire world, with the "New World", a term for the newly encountered lands of the Western Hemisphere, particularly the Americas. Etymology In the context of archaeology and world history, the term "Old World" includes those parts of the world which were in (indirect) cultural contact from the Bronze Age onwards, resulting in the parallel development of the early civilizations, mostly in the temperate zone between roughly the 45th and 25th parallels north, in the area of the Mediterranean, including North Africa. It also included Mesopotamia, the Persian plateau, the Indian subcontinent, China, and parts of Sub-Saharan Africa. These regions were connected via the Silk Road trade route, and they hav ...

Animal Echolocation
Echolocation, also called bio sonar, is a biological sonar used by several animal species. Echolocating animals emit calls out to the environment and listen to the echoes of those calls that return from various objects near them. They use these echoes to locate and identify the objects. Echolocation is used for navigation, foraging, and hunting in various environments. Echolocating animals include some mammals (most notably Laurasiatheria) and a few birds, especially some bat species and odontocetes (toothed whales and dolphins), but also in simpler forms in other groups such as shrews, and two cave-dwelling bird groups, the so-called cave swiftlets in the genus '' Aerodramus'' (formerly ''Collocalia'') and the unrelated oilbird ''Steatornis caripensis''. Early research The term ''echolocation'' was coined in 1938 by the American zoologist Donald Griffin, who, with Robert Galambos, first demonstrated the phenomenon in bats. As Griffin described in his book, the 18t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Macroderma (bat)
''Macroderma'' is a genus of microbats, present in the fossil record and as one extant species. They have existed in Australia since the early Miocene. Taxonomy The description to the genus was published in a revision of chiropterans by Gerrit Smith Miller Jr. in 1906, separating the type species from it placement in the genus ''Megaderma''. The taxonomic placement is to family Megadermatidae of the suborder Microchiroptera. The name ''Macroderma'' combines the Greek words ''macros'' (large) and ''derma'' (skin), due to the large size of their partially conjoined ears. * ''Macroderma gigas'' Dobson, 1880 the only living species, a large predatory carnivore referred to as the Australian false vampyre or ghost bat * '' Macroderma godthelpi'', a fossil taxon describing the earliest and smallest species * '' Macroderma koppa'' Hand, Dawson & Augee, 1988. a fossil species that existed in the Pliocene epoch. * '' Macroderma malugara'' S.

Sagittal Crest
A sagittal crest is a ridge of bone running lengthwise along the midline of the top of the skull (at the sagittal suture) of many mammalian and reptilian skulls, among others. The presence of this ridge of bone indicates that there are exceptionally strong jaw muscles. The sagittal crest serves primarily for attachment of the temporalis muscle, which is one of the main chewing muscles. Development of the sagittal crest is thought to be connected to the development of this muscle. A sagittal crest usually develops during the juvenile stage of an animal in conjunction with the growth of the temporalis muscle, as a result of convergence and gradual heightening of the temporal lines. Function A sagittal crest tends to be present on the skulls of adult animals that rely on powerful biting and clenching of their teeth, usually as a part of their hunting strategy. Skulls of some dinosaur species, including tyrannosaurs, possessed well developed sagittal crests. Among mammals, dogs, cats, ...

Lambdoidal
The lambdoid suture (or lambdoidal suture) is a dense, fibrous connective tissue joint on the posterior aspect of the skull that connects the parietal bones with the occipital bone. It is continuous with the occipitomastoid suture. Structure The lambdoid suture is between the paired parietal bones and the occipital bone of the skull. It runs from the asterion on each side. Nerve supply The lambdoid suture may be supplied by a branch of the supraorbital nerve, a branch of the frontal branch of the trigeminal nerve. Clinical significance At birth, the bones of the skull do not meet. If certain bones of the skull grow too fast, then craniosynostosis (premature closure of the sutures) may occur. This can result in skull deformities. If the lambdoid suture closes too soon on one side, the skull will appear twisted and asymmetrical, a condition called "plagiocephaly". Plagiocephaly refers to the shape and not the condition. The condition is craniosynostosis. The lambdoid sutu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miocene Bats
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.
