Eucryphia Falcata
''Eucryphia falcata'' is an extinct species of flowering plant. It belongs to the genus ''Eucryphia'' within the family '' Cunoniaceae''.''Eucryphia falcata'' Hill, 1991. (n.d.). GBIF , Global Biodiversity Information Facility. Retrieved November 9, 2022, from https://www.gbif.org/species/8606557 Description Macrofossils of compound leaves with an unknown number of total leaflets have been found. The lateral leaflets are falcate, and the terminal leaflet is symmetrical. It has a rounded base. The leaf margin had serrations. This is likely the plesiomorphic condition for all genera of the family Cunoniaceae.Barnes, R. W., & Jordan, G. J. (2000)"Eucryphia (Cunoniaceae) reproductive and leaf macrofossils from Australian Cainozoic sediments."Australian Systematic Botany, 13(3), 373-394. The leaves also had trichomes. Etymology The specific epithet ''falcata'' is derived from the falcate, lateral leaflets of the compound leaves. Temporal range This species lived during the la ...

Year
A year or annus is the orbital period of a planetary body, for example, the Earth, moving in its orbit around the Sun. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by change in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar regions around the planet, four seasons are generally recognized: spring, summer, autumn and winter. In tropical and subtropical regions, several geographical sectors do not present defined seasons; but in the seasonal tropics, the annual wet and dry seasons are recognized and tracked. A calendar year is an approximation of the number of days of the Earth's orbital period, as counted in a given calendar. The Gregorian calendar, or modern calendar, presents its calendar year to be either a common year of 365 days or a leap year of 366 days, as do the Julian calendars. For the Gregorian calendar, the average length of the calendar yea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bunyan, New South Wales
Bunyan is a locality in the Snowy Monaro Region, New South Wales, Australia. It lies on the eastern side of the Murrumbidgee River and on both sides of the Monaro Highway about 110 km south of Canberra and about 10 km north of Cooma. At the , it had a population of 152. The area now known as Bunyan lies on the traditional lands of the Ngarigo people. The name is said to be from an Aboriginal language word, ''Boonyan'', meaning "Place where pigeons stay". Lying on the direct route from Queanbeyan to the Monaro hinterland and with flats suited to grazing, it was a suitable site for colonial settlement. The first settler there was Dr Reid, in the early 1830s, and the area was known as Reid's Flats until 1858. There was an inn there from around 1832. The area was also known locally as 'Jews' Flats'. From the 1830s until at least the mid-1850s, there were businesses there run by Jewish families named Solomon, Moses and Shannon. The last hotel there, 'the Squatters' Arms' ...

Eucryphia
''Eucryphia'' is a small genus of trees and large shrubs native to the south temperate regions of South America and coastal eastern Australia, mainly Tasmania. Sometimes placed in a family of their own, the Eucryphiaceae, more recent classifications place them in the Cunoniaceae. There are seven species, two in South America and five in Australia, and several named hybrids. Description They are mostly evergreen though one species (''E. glutinosa'') is usually deciduous. The leaves are opposite, and either simple or pinnate with 3-13 leaflets. The flowers are produced in late summer or autumn, are showy and sweetly scented, 3–6 cm diameter, with four creamy-white petals, and numerous stamens and styles. The fruit is a woody capsule 1-1.5 cm long containing several seeds, and maturing in 12–15 months. Etymology The generic name ''Eucryphia'' is composed of two parts, namely ''eu-'' and ''-cryphia''. The Greek ευ-κρυφαιος means well-covered and refers t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extinct Plants
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] |
Prehistoric Plants
Paleobotany, which is also spelled as palaeobotany, is the branch of botany dealing with the recovery and identification of plant remains from geological contexts, and their use for the biological reconstruction of past environments (paleogeography), and the evolutionary history of plants, with a bearing upon the evolution of life in general. A synonym is paleophytology. It is a component of paleontology and paleobiology. The prefix ''palaeo-'' means "ancient, old", and is derived from the Greek adjective , . Paleobotany includes the study of terrestrial plant fossils, as well as the study of prehistoric marine photoautotrophs, such as photosynthetic algae, seaweeds or kelp. A closely related field is palynology, which is the study of fossilized and extant spores and pollen. Paleobotany is important in the reconstruction of ancient ecological systems and climate, known as paleoecology and paleoclimatology respectively; and is fundamental to the study of green plant development ...

Fossils
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 ab ...

Flora Of Australia
The flora of Australia comprises a vast assemblage of plant species estimated to over 30,000 vascular and 14,000 non-vascular plants, 250,000 species of fungi and over 3,000 lichens. The flora has strong affinities with the flora of Gondwana, and below the family level has a highly endemic angiosperm flora whose diversity was shaped by the effects of continental drift and climate change since the Cretaceous. Prominent features of the Australian flora are adaptations to aridity and fire which include scleromorphy and serotiny. These adaptations are common in species from the large and well-known families Proteaceae ('' Banksia''), Myrtaceae (''Eucalyptus'' - gum trees), and Fabaceae (''Acacia'' - wattle). The arrival of humans around 50,000 years ago and the settlement by Europeans from 1788, has had a significant impact on the flora. The use of fire-stick farming by Aboriginal people led to significant changes in the distribution of plant species over time, and the lar ...
