Araucaria Haastii
''Araucaria haastii'' is an extinct species of conifer tree formerly native to New Zealand. A large number of fossilised tree specimens from the family Araucariaceae have been found in New Zealand, but in many cases the level of preservation is not sufficient to reliably distinguish between ''Araucaria'' species (related to extant modern trees such as the Norfolk pine) and '' Agathis'' species (related to New Zealand's kauri tree). ''Araucaria haastii'' is known from some of the better preserved fossils, found in Cretaceous sediments from several sites in the South Island. These fossils show sufficiently detailed morphology and cuticular structure in the leaves to allow this species not only to be definitively identified as an ''Araucaria'', but also to place it within the ''Intermedia'' section of this genus, meaning that its closest living relative is the klinki pine found in the mountains of Papua New Guinea. North Island fossil specimens from the same time period appear to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Constantin Von Ettingshausen
Constantin Freiherr von Ettingshausen (or Baron Constantin von Ettingshausen) (16 June 1826 in Vienna – 1 February 1897 in Graz) was an Austrian botanist known for his paleobotanical studies of flora from the Tertiary era. He was the son of physicist Andreas von Ettingshausen. Biography In 1848 he graduated as a doctor of medicine in Vienna, and became in 1854 a professor of botany and natural history at the medical and surgical military academy in that city. In 1871 he was chosen professor of botany at Graz, a position which he maintained until the close of his life. From 1876 he made repeated visits to London, where he arranged collections at the Natural History Museum. He was distinguished for his researches on the Tertiary floras of various parts of Europe, and on the fossil floras of Australia and New Zealand. The extinct genus ''Ettingshausenia'' (family Vitaceae The Vitaceae are a family of flowering plants, with 14 genera and around 910 known species, includi ...

Papua New Guinea
Papua New Guinea, officially the Independent State of Papua New Guinea, is an island country in Oceania that comprises the eastern half of the island of New Guinea and offshore islands in Melanesia, a region of the southwestern Pacific Ocean north of Australia. It has Indonesia–Papua New Guinea border, a land border with Indonesia to the west and neighbours Australia to the south and the Solomon Islands to the east. Its capital, on its southern coast, is Port Moresby. The country is the world's third largest list of island countries, island country, with an area of . The nation was split in the 1880s between German New Guinea in the North and the Territory of Papua, British Territory of Papua in the South, the latter of which was ceded to Australia in 1902. All of present-day Papua New Guinea came under Australian control following World War I, with the legally distinct Territory of New Guinea being established out of the former German colony as a League of Nations mandate.

Extinct Flora Of New Zealand
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 ...

Cretaceous Plants
The Cretaceous ( ) is a geological period that lasted from about 143.1 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 77.1 million years, it is the ninth and longest geological period of the entire Phanerozoic. The name is derived from the Latin , 'chalk', which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation . The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels that created numerous shallow inland seas. These oceans and seas were populated with now-extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was largely ice-free, although there is some evidence of brief periods of glaciation during the cooler first half, and forests extended to the poles. Many of the dominant taxonomic groups present in modern times can be ultimately traced back to origins in the C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Banksia Novae-zelandiae
''Banksia novae-zelandiae'' is an extinction, extinct species of ''Banksia'', known only from fossil leaves found in the South Island of New Zealand. Description This species is based on several leaf fossils, all with triangular pinnate lobes cut all the way back to the midrib, and indistinct secondary venation. Stomata occur in areoles, and have very wrinkly subsidiary cells. Both leaf surfaces are covered in trichome bases, and the undersurface is covered in plant cuticle, cuticular papillae. Taxonomy Fossil leaves were found at the Newvale Mine, Waimumu Coalfield, Southland District, South Island, New Zealand (), in a thin leaf litter bed located in a seam of the middle Gore Lignite Measures. ''B. novae-zelandiae'' was first published in 2010. The specific epithet refers to New Zealand, where the fossils were found. The fossils are assigned to Banksieae based on several structural grounds, including brachyparacytic stomata, a trichome base architecture unique to Banksi ...

Araucaria Mirabilis
''Araucaria mirabilis'' is an extinct species of coniferous tree from Patagonia, Argentina. It belongs to the genus ''Araucaria''. ''A. mirabilis'' are known from large amounts of very well preserved silicified wood and cones from the Cerro Cuadrado Petrified Forest, including tree trunks that reached in height in life. The site was buried by a volcanic eruption during the Middle Jurassic, approximately 160 million years ago. Discovery Fossils of ''Araucaria mirabilis'' are found in great abundance in the Cerro Cuadrado Petrified Forest of Patagonia, Argentina. They were the dominant species of a forest buried by a volcanic eruption about 160 million years ago. The petrified forests of ''A. mirabilis'' were first discovered in 1919 by the German- Argentinean botanist Anselmo Windhausen. Noting that petrified cones were being kept as souvenirs by local farmers in the area, he explored the region and discovered the site of the petrified forests in 1923. He sent the specimens h ...

Gondwana
Gondwana ( ; ) was a large landmass, sometimes referred to as a supercontinent. The remnants of Gondwana make up around two-thirds of today's continental area, including South America, Africa, Antarctica, Australia (continent), Australia, Zealandia, Arabian Peninsula, Arabia, and the Indian subcontinent. Gondwana was formed by the Accretion (geology), accretion of several cratons (large stable blocks of the Earth's crust), beginning with the East African Orogeny, the collision of India and Geography of Madagascar, Madagascar with East Africa, and culminating in with the overlapping Brasiliano orogeny, Brasiliano and Kuunga orogeny, Kuunga orogenies, the collision of South America with Africa, and the addition of Australia and Antarctica, respectively. Eventually, Gondwana became the largest piece of continental crust of the Paleozoic Era, covering an area of some , about one-fifth of the Earth's surface. It fused with Laurasia during the Carboniferous to form Pan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
