Bothriomyrmex Constricta
''Yantaromyrmex'' is an extinct genus of ants first described in 2013. Members of this genus are in the subfamily Dolichoderinae of the family Formicidae, known from Middle Eocene to Early Oligocene fossils found in Europe. The genus currently contains five described species, ''Y. constrictus'', ''Y. geinitzi'', ''Y. intermedius'', ''Y. mayrianum'' and ''Y. samlandicus''. The first specimens were collected in 1868 and studied by Austrian entomologist Gustav Mayr, who originally placed the fossils in other ant genera until the fossils were reviewed and subsequently placed into their own genus. These ants are small, measuring from in length and can be characterized by their trapezoidal shaped head-capsules and oval compound eyes that are located slightly to the rear of the capsules midpoint, with no known ocelli present. Distribution Individuals of ''Yantaromyrmex'' species have been found as inclusions in four different Middle Eocene to Early Oligocene amber deposits in Europe. ...

Callovian
In the geologic timescale, the Callovian is an age and stage in the Middle Jurassic, lasting between 166.1 ± 4.0 Ma (million years ago) and 163.5 ± 4.0 Ma. It is the last stage of the Middle Jurassic, following the Bathonian and preceding the Oxfordian. Stratigraphic definitions The Callovian Stage was first described by French palaeontologist Alcide d'Orbigny in 1852. Its name derives from the latinized name for Kellaways Bridge, a small hamlet 3 km north-east of Chippenham, Wiltshire, England. The base of the Callovian is defined as the place in the stratigraphic column where the ammonite genus ''Kepplerites'' first appears, which is the base of the biozone of '' Macrocephalites herveyi''. A global reference profile (a GSSP) for the base had in 2009 not yet been assigned. The top of the Callovian (the base of the Oxfordian) is at the first appearance of ammonite species '' Brightia thuouxensis''. Subdivision The Callovian is often subdivided into three substages ( ...

Moffat Shales Group
Moffat ( gd, Mofad) is a burgh and parish in Dumfriesshire, now part of the Dumfries and Galloway local authority area in Scotland. It lies on the River Annan, with a population of around 2,500. It was a centre of the wool trade and a spa town. Moffat is around to the southeast of Glasgow, southwest of Edinburgh, northeast of Dumfries and northwest of Carlisle. The Moffat House Hotel, located at the northern end of the High Street, was designed by John Adam. The nearby Star Hotel, a mere 20 ft (6 m) wide, was listed in the Guinness Book of Records as the narrowest hotel in the world. Moffat won the Britain in Bloom contest in 1996. Moffat is home to Moffat toffee. The town is held to be the ancestral seat of Clan Moffat. The Devil's Beef Tub near Moffat was used by the members of Clan Moffat and later the members of Clan Johnstone to hoard cattle stolen in predatory raids. Early tourism as a spa town From 1633 Moffat began to grow from a small village into a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henry Alleyne Nicholson
Henry Alleyne Nicholson FRS FRSE FGS FLS (11 September 1844 – 19 January 1899) was a British palaeontologist and zoologist. Life The son of John Nicholson (1809–1886), a biblical scholar, and his wife Annie Elizabeth Waring, he was born at Penrith, Cumberland on 11 September 1844. His younger sister was the writer Annie Elizabeth Nicholson Ireland, and one of his brothers was John Henry Nicholson, author and poet. He was educated at Appleby Grammar School and then studied Sciences at the universities of Göttingen (Ph.D., 1866) and Edinburgh (D.Sc., 1867; M.D., 1869). Geology had early attracted his attention, and his first publication was a thesis for his D.Sc. degree titled ''On the Geology of Cumberland and Westmoreland'' (1868). In 1869 he began lecturing in Natural History at the extramural classes linked to Edinburgh University. In 1871 he was appointed professor of natural history in the University of Toronto; in 1874 professor of biology in the Durham College ...

Harry Seeley
Harry Govier Seeley (18 February 1839 – 8 January 1909) was a British paleontologist. Early life Seeley was born in London on 18 February 1839, the second son of Richard Hovill Seeley, a goldsmith, and his second wife Mary Govier. When his father was declared bankrupt, Seeley was sent to live with a family of piano makers. Between the ages of eleven and fourteen, he went to a day school and then spent the next two years learning to make pianos. He also attended lectures at the Royal School of Mines by Thomas Henry Huxley, Edward Forbes, and other notable scientists. In 1855, with the support of his uncle, Seeley began to study law but shortly gave it up to pursue a career as an actuary. In the late 1850s, he studied English and mathematics at the Working Men's College and served as a secretary for the college's museum. He also worked in the library of the British Museum, where Samuel Pickworth Woodward encouraged him to study geology. In 1859, Seeley began studies at Sidney Su ...

Pliosauridae
Pliosauridae is a family of plesiosaurian marine reptiles from the Latest Triassic to the early Late Cretaceous ( Rhaetian to Turonian stages) of Australia, Europe, North America and South America. The family is more inclusive than the archetypal short-necked large headed species that are placed in the subclade Thalassophonea, with basal forms resembling other plesiosaurs with long necks. They became extinct during the early Late Cretaceous and were subsequently replaced by the mosasaurs. It was formally named by Harry G. Seeley in 1874. Relationships Pliosauridae is a stem-based taxon defined in 2010 (and in earlier studies in a similar manner) as "all taxa more closely related to ''Pliosaurus brachydeirus'' than to '' Leptocleidus superstes'', '' Polycotylus latipinnis'' or ''Meyerasaurus victor''". The family Brachauchenidae has been proposed to include pliosauroids which have very short necks and may include ''Brachauchenius'' and ''Kronosaurus''. However, modern cladisti ...

Liopleurodon
''Liopleurodon'' (; meaning 'smooth-sided teeth') is an extinct genus of large, carnivorous marine reptile belonging to the Thalassophonea, a clade of short-necked pliosaurid plesiosaurs. ''Liopleurodon'' lived from the Callovian Stage of the Middle Jurassic to the Kimmeridgian stage of the Late Jurassic Period (c. 166 to 155 mya). It was the apex predator of the Middle to Late Jurassic seas that covered Europe. The largest species, ''L. ferox'', is estimated to have grown up to in length, but could have been larger. The name "Liopleurodon" (meaning "smooth-sided tooth") derives from Ancient Greek words: ', "smooth"; ', "side" or "rib"; and ', "tooth". Discovery and species Even before ''Liopleurodon'' was named, material likely belonging to it was described. In 1841, Hermann von Meyer named the species ''Thaumatosaurus oolithicus'' based on a fragmentary specimen consisting of partial teeth, skull elements, vertebrae, and ribs from deposits in Württemberg, Germany poss ...
