The Bendricks
The Bendricks is a stretch of coastline and an important paleontological site in the Vale of Glamorgan in south Wales located along the northern coast of the Bristol Channel between Barry and Sully at . It lies at the foreshore of the industrial port of Barry between the eastern breakwater of the Barry docks entrance on its western edge to Hayes Point on its eastern edge. This area of the coast is a Site of Special Scientific Interest. Geology and topography A tidal promontory of Carboniferous Limestone known as Bendrick Rock ( cy, Craig Bendrick) juts out from the mainland here. Only the highest part of the promontory at its seaward end normally remains visible at high tide, though the highest spring tides cover it entirely. The geology of the Bendricks consists primarily of mudstones, siltstones and conglomerates ( Mercia Mudstone marginal facies) formed primarily by deposition of silt at the shoreline of a shallow muddy sea during the Early and Late epochs of the Triassic ...

Triassic
The Triassic ( ) is a geologic period and system which spans 50.6 million years from the end of the Permian Period 251.902 million years ago ( Mya), to the beginning of the Jurassic Period 201.36 Mya. The Triassic is the first and shortest period of the Mesozoic Era. Both the start and end of the period are marked by major extinction events. The Triassic Period is subdivided into three epochs: Early Triassic, Middle Triassic and Late Triassic. The Triassic began in the wake of the Permian–Triassic extinction event, which left the Earth's biosphere impoverished; it was well into the middle of the Triassic before life recovered its former diversity. Three categories of organisms can be distinguished in the Triassic record: survivors from the extinction event, new groups that flourished briefly, and other new groups that went on to dominate the Mesozoic Era. Reptiles, especially archosaurs, were the chief terrestrial vertebrates during this time. A specialized subgroup of archo ...

HMS Cambria (shore Establishment)
HMS ''Cambria'' is the lead Royal Naval Reserve unit in Wales. It is based in the docks of the Welsh capital, Cardiff. History HMS ''Cambria'' was established as the Royal Naval Reserve unit for South Wales in July 1947 and originally occupied buildings in Cardiff Docks. ''Cambria'' remained in Cardiff until 1980, when the redevelopment of the docks there precipitated a move to the former service married couples' accommodation at Sully, Vale of Glamorgan, and was granted freedom of that county in 2012. Cambria returned to a purpose built home in Cardiff Docks in 2020. Over the years ''Cambria'', like many other RNR units, operated a number of seagoing ships; a motor minesweeper – the unit's first tender – was replaced in 1954 by the wooden-hulled minesweeper ''Brereton'', which gave way in turn to ''Crichton'' (1961–76); all of these were rechristened HMS ''St David''. In 1978 the unit acquired a converted trawler, which was again renamed ''St David''. The ship's final ve ...

Sauropodomorpha
Sauropodomorpha ( ; from Greek, meaning "lizard-footed forms") is an extinct clade of long-necked, herbivorous, saurischian dinosaurs that includes the sauropods and their ancestral relatives. Sauropods generally grew to very large sizes, had long necks and tails, were quadrupedal, and became the largest animals to ever walk the Earth. The '' prosauropods,'' which preceded the sauropods, were smaller and were often able to walk on two legs. The sauropodomorphs were the dominant terrestrial herbivores throughout much of the Mesozoic Era, from their origins in the Late Triassic (approximately 230 Ma) until their decline and extinction at the end of the Cretaceous. Description Sauropodomorphs were adapted to browsing higher than any other contemporary herbivore, giving them access to high tree foliage. This feeding strategy is supported by many of their defining characteristics, such as: a light, tiny skull on the end of a long neck (with ten or more elongated cervical vertebrae) ...

Grallator
''Grallator'' GRA-luh-tor"is an ichnogenus (form taxon based on footprints) which covers a common type of small, three-toed print made by a variety of bipedal theropod dinosaurs. ''Grallator''-type footprints have been found in formations dating from the Early Triassic through to the early Cretaceous periods. They are found in the United States, Canada, Europe, Australia, Brazil ( Sousa and Santa Maria Formations) and China,''Grallator''

Theropod
Theropoda (; ), whose members are known as theropods, is a dinosaur clade that is characterized by hollow bones and three toes and claws on each limb. Theropods are generally classed as a group of saurischian dinosaurs. They were ancestrally carnivorous, although a number of theropod groups evolved to become herbivores and omnivores. Theropods first appeared during the Carnian age of the late Triassic period 231.4 million years ago ( Ma) and included all the large terrestrial carnivores from the Early Jurassic until at least the close of the Cretaceous, about 66 Ma. In the Jurassic, birds evolved from small specialized coelurosaurian theropods, and are today represented by about 10,500 living species. Biology Diet and teeth Theropods exhibit a wide range of diets, from insectivores to herbivores and carnivores. Strict carnivory has always been considered the ancestral diet for theropods as a group, and a wider variety of diets was historically considered a characteri ...

Ichnospecies
An ichnotaxon (plural ichnotaxa) is "a taxon based on the fossilized work of an organism", i.e. the non-human equivalent of an artifact. ''Ichnotaxa'' comes from the Greek ίχνος, ''ichnos'' meaning ''track'' and ταξις, ''taxis'' meaning ''ordering''.Definition o'ichno'at dictionary.com. Ichnotaxa are names used to identify and distinguish morphologically distinctive ichnofossils, more commonly known as trace fossils. They are assigned genus and species ranks by ichnologists, much like organisms in Linnaean taxonomy. These are known as ichnogenera and ichnospecies, respectively. "Ichnogenus" and "ichnospecies" are commonly abbreviated as "igen." and "isp.". The binomial names of ichnospecies and their genera are to be written in italics. Most researchers classify trace fossils only as far as the ichnogenus rank, based upon trace fossils that resemble each other in morphology but have subtle differences. Some authors have constructed detailed hierarchies up to ichnosupe ...

Red Beds
Red beds (or redbeds) are sedimentary rocks, typically consisting of sandstone, siltstone, and shale, that are predominantly red in color due to the presence of ferric oxides. Frequently, these red-colored sedimentary strata locally contain thin beds of conglomerate, marl, limestone, or some combination of these sedimentary rocks. The ferric oxides, which are responsible for the red color of red beds, typically occur as a coating on the grains of sediments comprising red beds. Classic examples of red beds are the Permian and Triassic strata of the western United States and the Devonian Old Red Sandstone facies of Europe. Primary red beds Primary red beds may be formed by the erosion and redeposition of red soils or older red beds, but a fundamental problem with this hypothesis is the relative scarcity of red-colored source sediments of suitable age close to an area of red-bed sediments in Cheshire, England. Primary red beds may also form by in situ (early diagenetic) redd ...

National Museum Cardiff
National Museum Cardiff ( cy, Amgueddfa Genedlaethol Caerdydd) is a museum and art gallery in Cardiff, Wales. The museum is part of the wider network of Amgueddfa Cymru – National Museum Wales. Entry is kept free by a grant from the Welsh Government; however, they do ask for donations throughout the museum. History The National Museum of Wales was founded in 1905, with its royal charter granted in 1907. Part of the bid for Cardiff to obtain the National Museum for Wales included the gift of the Cardiff Museum Collection, then known as "Welsh Museum of Natural History, Archaeology and Art," which was formally handed over in 1912. The Cardiff Museum was sharing the building of Cardiff Library, and was a sub-department of the library until 1893. Construction of a new building in the civic complex of Cathays Park began in 1912, but owing to the First World War it did not open to the public until 1922, with the official opening taking place in 1927. The architects were Arnold Dun ...

Norian
The Norian is a division of the Triassic Period. It has the rank of an age (geochronology) or stage (chronostratigraphy). It lasted from ~227 to million years ago. It was preceded by the Carnian and succeeded by the Rhaetian. Stratigraphic definitions The Norian was named after the Noric Alps in Austria. The stage was introduced into scientific literature by Austrian geologist Edmund Mojsisovics von Mojsvar in 1869. The Norian Stage begins at the base of the ammonite biozones of '' Klamathites macrolobatus'' and '' Stikinoceras kerri'', and at the base of the conodont biozones of '' Metapolygnathus communisti'' and '' Metapolygnathus primitius''. A global reference profile for the base (a GSSP) had in 2009 not yet been appointed. The top of the Norian (the base of the Rhaetian) is at the first appearance of ammonite species '' Cochloceras amoenum''. The base of the Rheatian is also close to the first appearance of conodont species '' Misikella spp.'' and '' Epigondolella mo ...
