Duncan Merrilees
Duncan Merrilees (1922–2009) was an Australian geologist, palaeontologist, lecturer and curator at the Western Australian Museum. His research on the fossil records of mammals also founded examination into the period after the arrival of humans and their role within the ecology of the Australian continent. His excavations and research into mammalian palaeontology also included description of unknown species of extinct marsupials. Biography Merrilees was born in Sydney and graduated from the city's university with a degree in chemistry in 1942. His qualifications saw him deployed during the Second World War to a Tasmanian wood pulping industry. His interest was drawn at this time to the study of igneous rock and then to the examination of fossilised mammals. He moved to Western Australia in 1951, after discontinuing a teaching career, and began lecturing in scientific literacy at the University of Western Australia. An overlapping role with the works of the Western Australian M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geologist
A geologist is a scientist who studies the solid, liquid, and gaseous matter that constitutes Earth and other terrestrial planets, as well as the processes that shape them. Geologists usually study geology, earth science, or geophysics, although backgrounds in physics, chemistry, biology, and other sciences are also useful. Field research (field work) is an important component of geology, although many subdisciplines incorporate laboratory and digitalized work. Geologists can be classified in a larger group of scientists, called geoscientists. Geologists work in the energy and mining sectors searching for natural resources such as petroleum, natural gas, precious and base metals. They are also in the forefront of preventing and mitigating damage from natural hazards and disasters such as earthquakes, volcanoes, tsunamis and landslides. Their studies are used to warn the general public of the occurrence of these events. Geologists are also important contributors to climate ch ...

Quaternary Extinction Event
The Quaternary period (from 2.588 ± 0.005 million years ago to the present) has seen the extinctions of numerous predominantly megafaunal species, which have resulted in a collapse in faunal density and diversity and the extinction of key ecological strata across the globe. The most prominent event in the Late Pleistocene is differentiated from previous Quaternary pulse extinctions by the widespread absence of ecological succession to replace these extinct species, and the regime shift of previously established faunal relationships and habitats as a consequence. The earliest casualties were incurred at 130,000 BCE (the start of the Late Pleistocene), in Australia ~ 60,000 years ago, in Americas ~ 15,000 years ago, coinciding in time with the early human migrations. However, the great majority of extinctions in Afro-Eurasia and the Americas occurred during the transition from the Pleistocene to the Holocene epoch (13,000 BCE to 8,000 BCE). This extinction wave di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sthenurus
''Sthenurus'' ("strong tail") is an extinct genus of kangaroos. With a length around 3 m (10 ft), some species were twice as large as modern extant species. ''Sthenurus'' was related to the better-known ''Procoptodon''. The subfamily Sthenurinae is believed to have separated from its sister taxon, the Macropodinae (kangaroos and wallabies), halfway through the Miocene, and then its population grew during the Pliocene. Fossil habitats A 1997 study analysed the diets of fauna at various fossil site localities in South Australia, using stable carbon isotope analysis 13C/12C of collagen. It found that at older localities such as Cooper Creek, the species of ''Sthenurus'' were adapted to a diet of leaves and twigs (browsing) due to the wet climate of the time between 132 and 108 thousand years ago (kya - by thermoluminescence dating and uranium dating), which allowed for a more varied vegetation cover. At the Baldina Creek fossil site 30 kya ( C14 dating), the genus had t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Dortch
Charles Eugene Dortch (born 1940) is a US born archaeologist, largely known for his life and works in Western Australia. Biography Charlie Dortch was born in Atlanta, Georgia, where he began his interest in the peoples of the first nations, and in history and archaeology. He completed a degree in history from the University of Southern Mississippi and furthered his studies in the United Kingdom at University College London. Dortch was invited to apply for a position as curator of the archaeological department of the Western Australian Museum by Ian Crawford (anthropologist(, Ian Crawford, newly appointed to the museum's anthropology department. After settling in Western Australia, he joined the palaeontologist Duncan Merrilees in beginning a study of the site at Devils Lair, an important fossil site located in Southwest Australia (ecoregion), Southwest Australia. Many of the papers to which he contributed concern this site and its evidence of early mammalian fauna. In the early ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Devils Lair
Devil's Lair is a single-chamber cave with a floor area of around that formed in a Quaternary dune limestone of the Leeuwin–Naturaliste Ridge, from the modern coastline of Western Australia. The stratigraphic sequence in the cave floor deposit consists of of sandy sediments, with more than 100 distinct layers, intercalated with flowstone and other indurated deposits. Excavations have been made in several areas of the cave floor. Since 1973, excavations have been concentrated in the middle (approximately on a north-west, south-east axis) of the cave, where 10 trenches have been dug. Archaeological evidence for intermittent human occupation extends down about to layer 30, with hearths, bone, and stone artefacts found throughout. The site provides evidence of human habitation of Southwest Australia 50,000 years before the present day. Excavations Devil's Lair has been the subject of scientific research since the 1970s by palaeontologists and archaeologists. Excavations have r ...

Royal Society Of Western Australia
The Royal Society of Western Australia (RSWA) promotes science in Western Australia. The RSWA was founded in 1914. It publishes the ''Journal of the Royal Society of Western Australia'', and has awarded the Medal of the Royal Society of Western Australia (also known incorrectly as the Kelvin Medal) on an occasional basis since 1924. Journal The ''Journal of the Royal Society of Western Australia'' is a quarterly peer-reviewed scientific journal covering scientific research carried out in Western Australia, or on topics related to Western Australia.. It is the official journal of Royal Society of Western Australia and traces its roots to the ''Journal and Proceedings of the Mueller Botanic Society of Western Australia'' published from 1899 to 1903. The Mueller Botanic Society became the West Australian Natural History Society in 1903, and from 1904 to 1909, the journal was published as ''Journal of the West Australian Natural History Society''. In 1909 the society again changed it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Megafauna
In terrestrial zoology, the megafauna (from Greek μέγας ''megas'' "large" and New Latin ''fauna'' "animal life") comprises the large or giant animals of an area, habitat, or geological period, extinct and/or extant. The most common thresholds used are weight over see page 17 (i.e., having a mass comparable to or larger than a human) or over a tonne, (i.e., having a mass comparable to or larger than an ox). The first of these include many species not popularly thought of as overly large, and being the only few large animals left in a given range/area, such as white-tailed deer, Thomson's gazelle, and red kangaroo. In practice, the most common usage encountered in academic and popular writing describes land mammals roughly larger than a human that are not (solely) domesticated. The term is especially associated with the Pleistocene megafauna – the land animals often larger than their extant counterparts that are considered archetypical of the last ice age, such as mammoth ...
