Moythomasia (named for James Alan Moy-Thomas) [1] is an extinct genus of early ray-finned fish from the Devonian period of Europe and Australia.

Moythomasia was a small freshwater fish, 9 centimetres (3.5 in) long. It had relatively large eyes, presumably to find prey in murky water. Its body was covered in specialized ganoid scales; the upper side of each scale sported a small pin that perfectly fit into the hollow lower side of the next scale. This allowed the fish to be both armored and flexible. [2]

The Monument to the Great Fire of London, more commonly known simply as the Monument, is a fluted Doric column in London, England, situated near the northern end of London Bridge. Commemorating the Great Fire of London, it stands at the junction of Monument Street and Fish Street Hill, 202 feet (62 m) in height and 202 feet west of the spot in Pudding Lane where the Great Fire started on 2 September 1666. Constructed between 1671 and 1677, it was built on the site of St Margaret, New Fish Street, the first church to be destroyed by the Great Fire. It is Grade I-listed and is a scheduled monument. Another monument, the Golden Boy of Pye Corner, marks the point near Smithfield where the fire was stopped.

<i>Drepanaspis</i> Extinct genus of jawless fishes

Drepanaspis is an extinct genus of primitive jawless Ostracoderms from the Early Devonian that belonged to the phylum Chordata, infraphylum Agnatha, class Pteraspidomorphi, and the subclass Heterostraci. Drepanaspis are assumed to have lived primarily in marine environments and is most commonly characterized by their ray-like, heavily armored bodies, along with their lack of paired fins and jaws.

<i>Cheirolepis</i> Extinct genus of fishes

Cheirolepis is an extinct genus of ray-finned fish that lived in the Devonian period of Europe and North America. It is the only genus yet known within the family Cheirolepidae and the order Cheirolepiformes. It was among the most basal of the Devonian actinopterygians and is considered the first to possess the "standard" dermal cranial bones seen in later actinopterygians.

<i>Palaeoniscum</i> Extinct genus of fishes

Palaeoniscum is an extinct genus of ray-finned fish from the Permian period (Guadalupian-Lopingian) of England, Germany, Turkey, North America and Greenland, and possibly other regions. The genus was named Palaeoniscum in 1818 by Henri Marie Ducrotay de Blainville, but was later misspelled as Palaeoniscus by Blainville and other authors. Palaeoniscum belongs to the family Palaeoniscidae.

Pholidophorus is an extinct genus of stem-teleost fish. Numerous species were assigned to this genus in the past, but only the type species Pholidophorus latiusculus, from the Late Triassic of Europe, is considered to be a valid member of the genus today.

<i>Pholidogaster</i> Extinct genus of tetrapods

Pholidogaster is an extinct genus of stem-tetrapod that lived during the Middle Carboniferous period. Pholidogaster is known from only two specimens found in Gilmerton, Scotland. Historically it was one of the first to show science the evolutionary link between fish and amphibians.

The Orcadian Basin is a sedimentary basin of Devonian age that formed mainly as a result of extensional tectonics in northeastern Scotland after the end of the Caledonian orogeny. During part of its history, the basin was filled by a lake now known as Lake Orcadie. In that lacustrine environment, a sequence of finely bedded sedimentary rocks was deposited, containing well-preserved fish fossils, with alternating layers of mudstone and coarse siltstone to very fine sandstone. These flagstones split easily along the bedding and have been used as building material for thousands of years. The deposits of the Orcadian Basin form part of the Old Red Sandstone (ORS). The lithostratigraphic terms lower, middle and upper ORS, however, do not necessarily match exactly with sediments of lower, middle and upper Devonian age, as the base of the ORS is now known to be in the Silurian and the top in the Carboniferous.

<i>Rhadinichthys</i> Extinct genus of fishes

Rhadinichthys is an extinct genus of prehistoric bony fish. It is known from several species that lived in the Late Devonian epoch, the Carboniferous period and the Cisuralian epoch in what is now Europe, South Africa, and North and South America. Some isolated scales from the Cisuralian of Europe were also referred to this genus.

<span class="mw-page-title-main">Fish scale</span> Rigid covering growing atop a fishs skin

A fish scale is a small rigid plate that grows out of the skin of a fish. The skin of most jawed fishes is covered with these protective scales, which can also provide effective camouflage through the use of reflection and colouration, as well as possible hydrodynamic advantages. The term scale derives from the Old French escale, meaning a shell pod or husk.

HMS <i>Caroline</i> (1795) Frigate of the Royal Navy in service 1795–1812

HMS Caroline was a 36-gun fifth-rate Phoebe-class frigate of the Royal Navy. She was designed by Sir John Henslow and launched in 1795 at Rotherhithe by John Randall. Caroline was a lengthened copy of HMS Inconstant with improved speed but more instability. The frigate was commissioned in July 1795 under Captain William Luke to serve in the North Sea Fleet of Admiral Adam Duncan. Caroline spent less than a year in the North Sea before being transferred to the Lisbon Station. Here she was tasked to hunt down or interdict French shipping while protecting British merchant ships, with service taking her from off Lisbon to Cadiz and into the Mediterranean Sea. In 1799 the ship assisted in the tracking of the French fleet of Admiral Étienne Eustache Bruix, and in 1800 she participated in the blockade of Cadiz.
