Albert-Félix De Lapparent
Albert-Félix de Lapparent (; 1905–1975) was a French people, French Palaeontology, palaeontologist. He was also a Society of Saint-Sulpice, Sulpician priest. He undertook a number of fossil-hunting explorations in the Sahara desert. He contributed to knowledge about dinosaurs and other prehistoric creatures. In 1986, José Bonaparte named the dinosaur ''Lapparentosaurus'' in his honour. Dinosaurs named by Lapparent were ''Inosaurus tedreftensis'' (Lapparent, 1960) and ''Lusitanosaurus liassicus'' (Lapparent and Zbyszewski, 1957). New species of known genera are also credited to him. In alphabetical order, they are: ''Lourinhasaurus, Apatosaurus alenquerensis'' (Lapparent and Zbyszewski, 1957), ''Astrodon, Astrodon pusillus'' (Lapparent and Zbyszewski, 1957), ''Lusotitan, Brachiosaurus atalaiensis '' (Lapparent and Zbyszewski, 1957), ''Brachiosaurus nougaredi'' (Lapparent, 1960), ''Cetiosaurus, Cetiosaurus mogrebiensis'' (Lapparent, 1955), ''Elaphrosaurus, Elaphrosaurus gautieri' ...

Early Oligocene
The Rupelian is, in the geologic timescale, the older of two age (geology), ages or the lower of two stage (stratigraphy), stages of the Oligocene epoch (geology), Epoch/series (stratigraphy), Series. It spans the time between . It is preceded by the Priabonian Stage (part of the Eocene) and is followed by the Chattian Stage. Name The stage is named after the small river Rupel in Belgium, a tributary to the Scheldt. The Belgian Rupel Group derives its name from the same source. The name Rupelian was introduced in scientific literature by Belgian geologist André Hubert Dumont in 1850. The separation between the group (stratigraphy), group and the stage was made in the second half of the 20th century, when stratigraphers saw the need to distinguish between lithostratigraphy, lithostratigraphic and chronostratigraphy, chronostratigraphic names. Stratigraphic definition The base of the Rupelian Stage (which is also the base of the Oligocene Series) is at the extinction of the foram ...

Anatidae
The Anatidae are the biological family (biology), family of water birds that includes ducks, goose, geese, and swans. The family has a cosmopolitan distribution, occurring on all the world's continents except Antarctica. These birds are adapted for aquatic locomotion, swimming, floating on the water surface, and, in some cases, diving in at least shallow water. The family contains around 174 species in 43 genus, genera (the magpie goose is no longer considered to be part of the Anatidae and is now placed in its own family, Anseranatidae). They are generally herbivorous and are monogamy in animals, monogamous breeders. A number of species undertake bird migration, annual migrations. A few species have been domesticated for agriculture, and many others are hunted for food and recreation. Five species have become extinct since 1600, and many more are threatened with extinction. Description and ecology The ducks, geese, and swans are small- to large-sized birds with a broad and elo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pleistocene
The Pleistocene ( ; referred to colloquially as the ''ice age, Ice Age'') is the geological epoch (geology), epoch that lasted from to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek () 'most' and (; Latinized as ) 'new'. The aridification and cooling trends of the preceding Neogene were continued in the Pleistocene. The climate was strongly variable depending on the glacial cycle, oscillating between cold Glacial period, glacial periods and warmer Interglacial, int ...

Alexander Wetmore
Frank Alexander Wetmore (June 18, 1886 – December 7, 1978) was an American ornithologist and avian paleontologist. He was the sixth Secretary of the Smithsonian Institution. He was also an elected member of both the American Philosophical Society and the United States National Academy of Sciences. Early life and education The son of a physician, Frank Alexander Wetmore was born in North Freedom, Wisconsin. Developing an interest in birds at an early age, he made his first field journal entry (a pelican seen while on vacation in 1894) at the age of eight. By 1900, Wetmore published his first paper "My Experience with a Red-headed Woodpecker," in the magazine Bird-Lore. To further his education Wetmore enrolled at the University of Kansas in 1905. During his studies there he did a stint as an assistant in the University Museum, under the direction of Charles D. Bunker. Alexander Wetmore later received his BA from the University of Kansas in 1912; finally receiving his MS in 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anas Pachyscelus
The Bermuda flightless duck (''Anas pachyscelus'') is an extinct species of flightless duck which was endemic to the island of Bermuda in the North Atlantic Ocean. It was described in 1960 by Alexander Wetmore, from Late Pleistocene subfossil remains collected in 1956 by Bermudan ornithologist David Wingate, at the Wilkinson Quarry in Hamilton Parish. The holotype is a left tarsometatarsus (Specimen No. V22506) held in the National Museum of Natural History in Washington, D.C. Washington, D.C., formally the District of Columbia and commonly known as Washington or D.C., is the capital city and federal district of the United States. The city is on the Potomac River, across from Virginia, and shares land borders with ...

Woolungasaurus
''Woolungasaurus'' ('Woolunga lizard', named after an Aboriginal mythical reptile, Persson 1960) is a dubious genus of plesiosaur, an extinct marine reptile, belonging to the Elasmosauridae. History The type species, ''Woolungasaurus glendowerensis'', was named after Glendower Station by Per Ove Persson in 1960,Persson, P.O., 1960, "Lower Cretaceous Plesiosaurians (Reptilia) from Australia", ''Lunds Universitets Arsskrift'' 56(12): 1-23 is known from a partial skeleton, holotype QM F6890, (forty-six vertebrae, ribs, forearms, shoulder girdle and part of the rear limbs) unearthed from the Wallumbilla Formation (Albian, Lower Cretaceous) of the Richmond District, Queensland, Australia. Another find of undetermined species, consisting of twelve vertebrae, was unearthed from the Maree Formation (Cretaceous, of uncertain age) of Neales River, near Lake Eyre, South Australia. A skull formerly referred to this genus from Yambore Creek, near Maxwelton, Queensland, is now the holoty ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nodosaur
Nodosauridae is a family of ankylosaurian dinosaurs known from the Late Jurassic to the Late Cretaceous periods in what is now Asia, Europe, North America, and possibly South America. While traditionally regarded as a monophyletic clade as the sister taxon to the Ankylosauridae, some analyses recover it as a paraphyletic grade leading to the ankylosaurids. Description Nodosaurids, like their sister group the ankylosaurids, were heavily armored dinosaurs adorned with rows of bony armor nodules and spines (osteoderms), which were covered in keratin sheaths. Ankylosaurians were small- to large-sized, heavily built, quadrupedal, herbivorous dinosaurs, possessing small, leaf-shaped teeth. Unlike ankylosaurids, nodosaurids lacked mace-like tail clubs and instead had more flexible tail tips. Many nodosaurids had spikes projecting outward from their shoulders. One particularly well-preserved nodosaurid "mummy", the holotype of '' Borealopelta markmitchelli'', preserves a nearly complet ...
