Eathiestrobus
''Eathiestrobus mackenziei'' is a fossil pine cone found in the Kimmeridge Clay Formation (Upper Jurassic) near Eathie, on the Black Isle in Scotland. It is the oldest fossil pine currently known. Etymology The genus name ''Eathiestrobus'' refers to the place it was found, Eathie, in Scotland, and ''strobus'', which means cone. The species name ''mackenziei'' honors Mr. W. Mackenzie, who collected the specimen and donated it to the Hunterian Museum in 1896. Description The holotype of ''Eathiestrobus mackenziei'' consists of an incomplete, 8 cm long seed cone. It is held in the Hunterian Museum and Art Gallery The Hunterian is a complex of museums located in and operated by the University of Glasgow in Glasgow, Scotland. It is the oldest museum in Scotland. It covers the Hunterian Museum, the Hunterian Art Gallery, the Mackintosh House, the Zoology ... in Glasgow, and was originally identified as '' Pityostrobus'', but later re-examined and reclassified as a new genus and ...

Pinaceae
The Pinaceae, or pine family, are conifer trees or shrubs, including many of the well-known conifers of commercial importance such as cedars, firs, hemlocks, larches, pines and spruces. The family is included in the order Pinales, formerly known as Coniferales. Pinaceae are supported as monophyletic by their protein-type sieve cell plastids, pattern of proembryogeny, and lack of bioflavonoids. They are the largest extant conifer family in species diversity, with between 220 and 250 species (depending on taxonomic opinion) in 11 genera, and the second-largest (after Cupressaceae) in geographical range, found in most of the Northern Hemisphere, with the majority of the species in temperate climates, but ranging from subarctic to tropical. The family often forms the dominant component of boreal, coastal, and montane forests. One species, ''Pinus merkusii'', grows just south of the equator in Southeast Asia. Major centres of diversity are found in the mountains of southwest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kimmeridge Clay
The Kimmeridge Clay is a sedimentary deposit of fossiliferous marine clay which is of Late Jurassic to lowermost Cretaceous age and occurs in southern and eastern England and in the North Sea. This rock formation is the major source rock for North Sea oil. The fossil fauna of the Kimmeridge Clay includes turtles, crocodiles, sauropods, plesiosaurs, pliosaurs and ichthyosaurs, as well as a number of invertebrate species. Description Kimmeridge Clay is named after the village of Kimmeridge on the Dorset coast of England, where it is well exposed and forms part of the Jurassic Coast World Heritage Site. Onshore, it is of Late Jurassic ( Kimmeridgian) age and outcrops across England, in a band stretching from Dorset in the south-west, north-east to North Yorkshire. Offshore, it extends into the Lower Cretaceous (Berriasian Stage) and it is found throughout the Southern, Central and Northern North Sea. The foundations of the Humber Bridge on the southern (Barton) side of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Upper Jurassic
The Late Jurassic is the third epoch of the Jurassic Period, and it spans the geologic time from 163.5 ± 1.0 to 145.0 ± 0.8 million years ago (Ma), which is preserved in Upper Jurassic strata.Owen 1987. In European lithostratigraphy, the name "Malm" indicates rocks of Late Jurassic age. In the past, ''Malm'' was also used to indicate the unit of geological time, but this usage is now discouraged to make a clear distinction between lithostratigraphic and geochronologic/chronostratigraphic units. Subdivisions The Late Jurassic is divided into three ages, which correspond with the three (faunal) stages of Upper Jurassic rock: Paleogeography During the Late Jurassic Epoch, Pangaea broke up into two supercontinents, Laurasia to the north, and Gondwana to the south. The result of this break-up was the spawning of the Atlantic Ocean. However, at this time, the Atlantic Ocean was relatively narrow. Life forms of the epoch This epoch is well known for many famous types of dinosau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Isle
The Black Isle ( gd, an t-Eilean Dubh, ) is a peninsula within Ross and Cromarty, in the Scottish Highlands. It includes the towns of Cromarty and Fortrose, and the villages of Culbokie, Jemimaville, Rosemarkie, Avoch, Munlochy, Tore, and North Kessock, as well as numerous smaller settlements. About 12,000 people live on the Black Isle, depending on the definition. The northern slopes of the Black Isle offer fine views of Dingwall, Ben Wyvis, Fyrish and the deepwater anchorage at Invergordon. To the south, Inverness and the Monadhliath Mountains can be seen. Description Despite its name, the Black Isle is not an island but a peninsula, surrounded on three sides by the sea – the Cromarty Firth to the north, the Beauly Firth to the south, and the Moray Firth to the east. On the fourth, western side, its boundary is broadly delineated by rivers. The River Conon, which divides Maryburgh from Conon Bridge, defines the border in the north-west. The south-weste ...

Holotype
A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany, an isotype is a duplicate of the holotype, where holotype and isotypes are often pieces from the same individual plant or samples from the same gathering. A holotype is not necessarily " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hunterian Museum And Art Gallery
The Hunterian is a complex of museums located in and operated by the University of Glasgow in Glasgow, Scotland. It is the oldest museum in Scotland. It covers the Hunterian Museum, the Hunterian Art Gallery, the Mackintosh House, the Zoology Museum and the Anatomy Museum, which are all located in various buildings on the main campus of the university in the west end of Glasgow. History In 1783, William Hunter, a Scottish anatomist and physician who studied at the University of Glasgow, died in London. His will stipulated that his substantial and varied collections should be donated to the University of Glasgow. Hunter, writing to Dr William Cullen, stated that they were "to be well and carefully packed up and safely conveyed to Glasgow and delivered to the Principal and Faculty of the College of Glasgow to whom I give and bequeath the same to be kept and preserved by them and their successors for ever... in such sort, way, manner and form as ... shall seem most fit and most c ...

Pinus Yorkshirensis
''Pinus yorkshirensis'' is an extinct species of pine tree. The fossil pine cone came from Hauterivian and Barremian-aged sedimentary rocks located in the Speeton Clay in Yorkshire (hence the species epithet). Discovery and naming The type specimen of ''Pinus yorkshirensis'' was discovered during a field trip at the University of Birmingham. It is one of four known fossil pine cones from Europe Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a subcontinent of Eurasia and it is located entirel .... It was 5 million years older than the previous record holder, '' Pinus belgica''. The fossil was destroyed for science so scientists could study the fossil in more detail. All that remains are a few microscope slides and a single image. They are currently housed at Lapworth Museum of Geology. References Cretaceous plants yorkshir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
