Pendraig Milnerae Skeleton
''Pendraig'' (meaning "chief dragon" in Middle Welsh) is a genus of coelophysoid theropod dinosaur from South Wales. It contains one species, ''Pendraig milnerae'', named after Angela Milner. The specimen was discovered in the Pant-y-Ffynnon Quarry, Pant-y-Ffynnon quarry. In life it would have measured in length. History The holotype of ''Pendraig'' were found in the Pant-y-Ffynnon Quarry, Pant-y-ffynnon Quarry in Wales in 1952 by Kenneth Kermack, Kenneth Alexander Kermack and Pamela Lamplugh Robinson along with the holotypes of ''Pantydraco'' and ''Terrestrisuchus'', and were subsequently lost in the collections of the Natural History Museum, London. The fossils were originally thought to belong to a "coelurosaur" (in the outdated sense of the word) and even subsequently classified as a species of "''Syntarsus''" (now ''Megapnosaurus'' or ''Coelophysis''). Recently Angela Milner and Susannah Maidment rediscovered the fossils stored with some crocodile bones (likely ''Terrestris ...

Late Triassic
The Late Triassic is the third and final epoch (geology), epoch of the Triassic geologic time scale, Period in the geologic time scale, spanning the time between annum, Ma and Ma (million years ago). It is preceded by the Middle Triassic Epoch and followed by the Early Jurassic Epoch. The corresponding series (stratigraphy), series of rock beds is known as the Upper Triassic. The Late Triassic is divided into the Carnian, Norian and Rhaetian Geologic time scale, ages. Many of the first dinosaurs evolved during the Late Triassic, including ''Plateosaurus'', ''Coelophysis'', ''Herrerasaurus'', and ''Eoraptor''. The Triassic–Jurassic extinction event began during this epoch and is one of the five major mass extinction events of the Earth. Etymology The Triassic was named in 1834 by Friedrich August von Namoh, Friedrich von Alberti, after a succession of three distinct rock layers (Greek meaning 'triad') that are widespread in southern Germany: the lower Buntsandstein (colourful ...

Susannah Maidment
Susannah "Susie" Catherine Rose Maidment is a British palaeontologist at the Natural History Museum, London. She is also an honorary Professor at the University of Birmingham. She is internationally recognised for her research on ornithischian dinosaur evolution, and was awarded the 2016 Hodson Award of the Palaeontological Association and the 2017 Lyell Fund of the Geological Society of London. She was featured as a 2019 National Geographic Women of Impact. Education and career Maidment studied geology at Imperial College London, graduating with an MSc in 2003. She completed her PhD at the University of Cambridge in 2007, in which she studied the systematics of the dinosaur group Stegosauria. Her research was supervised by David Norman and Paul Upchurch. Following time working as an exploration geologist in Vietnam, she moved in 2009 to work with Paul Barrett at the Natural History Museum, London, as a postdoctoral researcher co-investigator on a NERC-funded project on ornith ...

Rhynchocephalia
Rhynchocephalia (; ) is an order of lizard-like reptiles that includes only one living species, the tuatara (''Sphenodon punctatus'') of New Zealand. Despite its current lack of diversity, during the Mesozoic rhynchocephalians were a speciose group with high morphological and ecological diversity. The oldest record of the group is dated to the Middle Triassic around 238 to 240 million years ago, and they had achieved global distribution by the Early Jurassic. Most rhynchocephalians belong to the group Sphenodontia ('wedge-teeth'). Their closest living relatives are lizards and snakes in the order Squamata, with the two orders being grouped together in the superorder Lepidosauria. Rhynchocephalians are distinguished from squamates by a number of traits, including the retention of rib-like gastralia bones in the belly, as well as most rhynchocephalians having acrodont teeth that are fused to the crests of the jaws (the latter also found among a small number of modern lizard grou ...

Thecodontosaurus
''Thecodontosaurus'' ("socket-tooth lizard") is a genus of herbivorous basal sauropodomorph dinosaur that lived during the late Triassic period (Carnian? age). Its remains are known mostly from Triassic "fissure fillings" in South England. ''Thecodontosaurus'' was a small bipedal animal, about 2 m (6.5 ft) long. It is one of the first dinosaurs to be discovered and is one of the oldest that existed. Many species have been named in the genus, but only the type species ''Thecodontosaurus antiquus'' is seen as valid today. Discovery and naming ''Thecodontosaurus antiquus'' In the autumn of 1834, surgeon Henry Riley (1797–1848) and the curator of the Bristol Institution, Samuel Stutchbury, began to excavate "saurian remains" at the quarry of Durdham Down, at Clifton, presently a part of Bristol, which is part of the Magnesian Conglomerate. In 1834 and 1835, they briefly reported on the finds. They provided their initial description in 1836, naming a new genus: '' ...

Aenigmaspina
''Aenigmaspina'' (from Latin ''aenigma'' and ''spina'', meaning "enigmatic spine") is an extinct genus of enigmatic pseudosuchian (= crurotarsan) archosaur from the Late Triassic of the United Kingdom. Its fossils are known from the Pant-y-ffynnon Quarry in South Wales, of which its type and only known species is named after, ''A. pantyffynnonensis''. ''Aenigmaspina'' is characterised by the unusual spines on its vertebrae, which are broad and flat on top with a unique 'Y' shape. Although parts of its skeleton is relatively well known, the affinities of ''Aenigmaspina'' to other pseudosuchians are unclear, although it is possibly related to families Ornithosuchidae, Erpetosuchidae or Gracilisuchidae. Description ''Aenigmaspina'' was a small (<1 m long) archosaur with a slender skeleton and build. It is mostly known from the front half of its body, including its |
Cayman Islands
The Cayman Islands () is a self-governing British Overseas Territories, British Overseas Territory, and the largest by population. The territory comprises the three islands of Grand Cayman, Cayman Brac and Little Cayman, which are located south of Cuba and north-east of Honduras, between Jamaica and Mexico's Yucatán Peninsula. The capital city is George Town, Cayman Islands, George Town on Grand Cayman, which is the most populous of the three islands.

The territory is a major offshore financial centre for international businesses and High-net-worth individual, the rich mainly due to the state charging no tax on income earned or stored. With a GDP per capita of US$97,750 in 2023, the Cayman Islands has the highest standard of living in the Caribbean, and one of the highest in the world. Immigrants from over 140 countries and territories reside in the Cayman I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Life Reconstruction Of Pendraig Milnerae
Life, also known as biota, refers to matter that has biological processes, such as signaling and self-sustaining processes. It is defined descriptively by the capacity for homeostasis, organisation, metabolism, growth, adaptation, response to stimuli, and reproduction. All life over time eventually reaches a state of death, and none is immortal. Many philosophical definitions of living systems have been proposed, such as self-organizing systems. Viruses in particular make definition difficult as they replicate only in host cells. Life exists all over the Earth in air, water, and soil, with many ecosystems forming the biosphere. Some of these are harsh environments occupied only by extremophiles. Life has been studied since ancient times, with theories such as Empedocles's materialism asserting that it was composed of four eternal elements, and Aristotle's hylomorphism asserting that living things have souls and embody both Form (Plato), form and matter.
