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.

William Sutherland Dun
William Sutherland Dun (1 July 1868 – 7 October 1934) was an Australian palaeontologist, geologist and president of the Royal Society of New South Wales. Dun was the son of Major Percy Henderson Dun, formerly of the East India Company's army, and his wife Catherine Eliza Jane, , and was born at Cleveland House, Cheltenham, England. The family moved to Australia in 1869, and Dun was educated at Newington College (1882-1886)Newington College Register of Past Students 1863-1998 (Syd, 1999) pp55 and the University of Sydney. On 8 April 1890 Dun was employed as a probationer in the Geological Survey of New South Wales and was an assistant to Edgeworth David in his work on the Hunter River coalfield. Dun owed most of his training to Robert Etheridge, Junior. In 1892 Dun passed his final examinations in geology and palaeontology with first-class honours and in 1893 was made assistant palaeontologist to the geological survey. In 1899 he was appointed palaeontologist to the survey and i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extinction
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Long-beaked Echidna
The long-beaked echidnas (genus ''Zaglossus'') make up one of the two extant genera of echidnas, spiny monotremes that live in New Guinea; the other being the short-beaked echidna. There are three living species and one extinct species in this genus. The extinct species were present in Australia. Echidnas are one of the two types of mammals that lay eggs, the other being the platypus. The echidnas retain reptilian features such as egg-laying but display mammalian features such as fur and lactation. The Eastern species is listed as vulnerable, while Sir David's and western long-beaked echidna species are listed as Critically Endangered by the IUCN. Species ''Zaglossus attenboroughi'' * Habitat: known only from the Cyclops Mountains of Papua, Indonesia, New Guinea * Time: Holocene * Critically endangered Database entry includes justification for why this species is listed as critically endangered.

Gulgong, New South Wales
Gulgong is a 19th-century gold rush town in the Central Tablelands and the wider Central West regions of the Australian state of New South Wales. The town is situated within the Mid-Western Regional Council local government area. It is located about north west of Sydney, and about 30 km north of Mudgee along the Castlereagh Highway. At the 2016 Census, Gulgong had a population of 2,521. Today, much of the 19th-century character of the town remains, contributing to its appeal as a tourist destination. Of special interest is the Prince of Wales Opera House, a survivor with a rich history. An attraction of note is the ''Gulgong Pioneer Museum'', which has a huge collection of thematically-displayed exhibits, ranging from kitchen utensils to complete buildings that have been relocated to a "street" on the site. Apart from tourism and hospitality, local industries include wine production, wool, wheat growing and coal mining. Yarrobil National Park is located north west of Gu ...

Megalibgwilia
''Megalibgwilia'' is a genus of echidna known only from Australian fossils that incorporates the oldest-known echidna species. The genus ranged from the Miocene until the late Pleistocene, becoming extinct about 50,000 years ago. ''Megalibgwilia'' species were more widespread in warmer and moist climates. The extinction can be attributed to increasing aridification in Southern Australia. ''Megalibgwilia'' was first described from a broken left humerus by Richard Owen in 1884, as ''"Echidna" ramsayi''. Complete skulls and postcranial fossils have since been described. A second species, ''M. robusta'', was described in 1896 by Australian paleontologist William Sutherland Dun. ''Megalibgwilia'' comes from Greek ''mégas'' (μέγᾰς) and Wemba Wemba ''libgwil'' (plus the Latin suffix ''-ia''), meaning echidna. Although they are sometimes commonly referred to as giant echidnas, ''Megalibgwilia'' species are thought to have been similar in size to the contemporary western long- ...

Platypus
The platypus (''Ornithorhynchus anatinus''), sometimes referred to as the duck-billed platypus, is a semiaquatic, egg-laying mammal Endemic (ecology), endemic to Eastern states of Australia, eastern Australia, including Tasmania. The platypus is the sole living representative or monotypic taxon of its Family (biology), family (Ornithorhynchidae) and genus (''Ornithorhynchus''), though a number of Fossil Monotremes, related species appear in the fossil record. Together with the four species of echidna, it is one of the five wikt:extant, extant species of monotremes, mammals that lay Egg (biology), eggs instead of giving birth to live young. Like other monotremes, it senses prey through electroreception, electrolocation. It is one of the few species of venomous mammals, as the male platypus has a spur (zoology), spur on the hind foot that delivers a Platypus venom, venom, capable of causing severe pain to humans. The unusual appearance of this egg-laying, duck-billed, beaver-t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Humerus
The humerus (; ) is a long bone in the arm that runs from the shoulder to the elbow. It connects the scapula and the two bones of the lower arm, the radius and ulna, and consists of three sections. The humeral upper extremity consists of a rounded head, a narrow neck, and two short processes (tubercles, sometimes called tuberosities). The body is cylindrical in its upper portion, and more prismatic below. The lower extremity consists of 2 epicondyles, 2 processes (trochlea & capitulum), and 3 fossae (radial fossa, coronoid fossa, and olecranon fossa). As well as its true anatomical neck, the constriction below the greater and lesser tubercles of the humerus is referred to as its surgical neck due to its tendency to fracture, thus often becoming the focus of surgeons. Etymology The word "humerus" is derived from la, humerus, umerus meaning upper arm, shoulder, and is linguistically related to Gothic ''ams'' shoulder and Greek ''ōmos''.

Prehistoric Monotremes
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. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fossil Taxa Described In 1895
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''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the absol ...
