Thaumatosaurus
''Rhomaleosaurus'' (meaning "strong lizard") is an extinct genus of Early Jurassic (Toarcian age, about 183 to 175.6 million years ago) rhomaleosaurid pliosauroid known from Northamptonshire and from Yorkshire of the United Kingdom. It was first named by Harry Seeley in 1874 and the type species is ''Rhomaleosaurus cramptoni''. It was one of the earliest large marine reptile predators which hunted in the seas of Mesozoic era, with the type species ''R. cramptoni'' measuring long and weighing . Like other pliosaurs, ''Rhomaleosaurus'' fed on ichthyosaurs, ammonites and other plesiosaurs. Species ''R. cramptoni'' In July 1848, a fossil of a large plesiosaur was unearthed in an Alum quarry at Kettleness, near Whitby, in Yorkshire, England. It was collected from the ''A. bifrons'' ammonite zone of the Whitby Mudstone Formation, dating to the early Toarcian age, about 183 to 180 million years ago. The complete skeleton which preserved the skull, NMING F8785, was kept for five ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Early Jurassic
The Early Jurassic Epoch (geology), Epoch (in chronostratigraphy corresponding to the Lower Jurassic series (stratigraphy), Series) is the earliest of three epochs of the Jurassic Period. The Early Jurassic starts immediately after the Triassic-Jurassic extinction event, 201.3 Ma (million years ago), and ends at the start of the Middle Jurassic 174.1 Ma. Certain rocks of marine origin of this age in Europe are called "Lias Group, Lias" and that name was used for the period, as well, in 19th-century geology. In southern Germany rocks of this age are called Black Jurassic. Origin of the name Lias There are two possible origins for the name Lias: the first reason is it was taken by a geologist from an England, English quarryman's dialect pronunciation of the word "layers"; secondly, sloops from north Cornwall, Cornish ports such as Bude would sail across the Bristol Channel to the Vale of Glamorgan to load up with rock from coastal limestone quarries (lias limestone from S ...

Northamptonshire
Northamptonshire (; abbreviated Northants.) is a county in the East Midlands of England. In 2015, it had a population of 723,000. The county is administered by two unitary authorities: North Northamptonshire and West Northamptonshire. It is known as "The Rose of the Shires". Covering an area of 2,364 square kilometres (913 sq mi), Northamptonshire is landlocked between eight other counties: Warwickshire to the west, Leicestershire and Rutland to the north, Cambridgeshire to the east, Bedfordshire to the south-east, Buckinghamshire to the south, Oxfordshire to the south-west and Lincolnshire to the north-east – England's shortest administrative county boundary at 20 yards (19 metres). Northamptonshire is the southernmost county in the East Midlands. Apart from the county town of Northampton, other major population centres include Kettering, Corby, Wellingborough, Rushden and Daventry. Northamptonshire's county flower is the cowslip.

Mulgrave Castle
Mulgrave Castle refers to one of three structures on the same property in Lythe, near Whitby, North Yorkshire, England. One of these, known as the "old" or "ancient" castle, was by legend founded by Wada, a 6th-century ruler of Hälsingland. The second castle, () ''caput'' of the feudal barony of Mulgrave, was of Norman construction and remained active until destroyed by order of Parliament in 1647. The third is a country house () which was constructed by Lady Catherine Darnley and passed in 1718 by marriage into the Phipps family, when her daughter Lady Catherine Annesley married William Phipps. The Phipps family later held the titles of Baron Mulgrave, Earl of Mulgrave and Marquess of Normanby. History Ancient castle The 19th-century ''Handbook for Travellers in Yorkshire and for Residents in the County'' recounts that the ancient castle was built by Wada, ruler of Hälsingland. (Public domain.) Leland in his ''Itineraries'', circa 1545, refers to several local legends sup ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Museum Of Ireland
The National Museum of Ireland ( ga, Ard-Mhúsaem na hÉireann) is Ireland's leading museum institution, with a strong emphasis on national and some international archaeology, Irish history, Irish art, culture, and natural history. It has three branches in Dublin, the archaeology and natural history museums adjacent on Kildare Street and Merrion Square, and a newer Decorative Arts and History branch at the former Collins Barracks, and the Country Life museum in County Mayo. History Predecessors The National Museum of Ireland descends from the amalgamation of parts of the collections of a number of Dublin cultural institutions from the 18th and 19th centuries, including primarily the Royal Dublin Society (RDS) and the Royal Irish Academy (RIA). The earliest parts of the collections are largely geological and mineralogical specimens, which the RDS collected as a means to improve the knowledge and use of such resources in Ireland. The establishment of the museum collections ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skull
The skull is a bone protective cavity for the brain. The skull is composed of four types of bone i.e., cranial bones, facial bones, ear ossicles and hyoid bone. However two parts are more prominent: the cranium and the mandible. In humans, these two parts are the neurocranium and the viscerocranium ( facial skeleton) that includes the mandible as its largest bone. The skull forms the anterior-most portion of the skeleton and is a product of cephalisation—housing the brain, and several sensory structures such as the eyes, ears, nose, and mouth. In humans these sensory structures are part of the facial skeleton. Functions of the skull include protection of the brain, fixing the distance between the eyes to allow stereoscopic vision, and fixing the position of the ears to enable sound localisation of the direction and distance of sounds. In some animals, such as horned ungulates (mammals with hooves), the skull also has a defensive function by providing the mount (on the front ...

Skeleton
A skeleton is the structural frame that supports the body of an animal. There are several types of skeletons, including the exoskeleton, which is the stable outer shell of an organism, the endoskeleton, which forms the support structure inside the body, and the hydroskeleton, a flexible internal skeleton supported by fluid pressure. Vertebrates are animals with a vertebral column, and their skeletons are typically composed of bone and cartilage. Invertebrates are animals that lack a vertebral column. The skeletons of invertebrates vary, including hard exoskeleton shells, plated endoskeletons, or Sponge spicule, spicules. Cartilage is a rigid connective tissue that is found in the skeletal systems of vertebrates and invertebrates. Etymology The term ''skeleton'' comes . ''Sceleton'' is an archaic form of the word. Classification Skeletons can be defined by several attributes. Solid skeletons consist of hard substances, such as bone, cartilage, or cuticle. These can be further ...

Kettleness
Kettleness, is a hamlet in the Scarborough District of North Yorkshire, England. The settlement only consists of half-a-dozen houses, but up until the early 19th century, it was a much larger village. However, most of that village, which was on the headland, slipped into the sea as a result of instability caused by quarrying for the alum industry. Kettleness became a smaller settlement, with houses rebuilt slightly further inland. Historically, the hamlet has had an alum works, a jet mining industry and ironstone workings. The hamlet used to have a railway station on the Whitby, Redcar and Middlesbrough Union Railway, that was open between 1883 and 1958. Kettleness is recorded within the parish of Lythe for census purposes. History Kettleness is not mentioned in the Domesday Book, but the neighbouring settlement of Goldsborough is, and both were in the Wapentake of Langbaurgh. The hamlet takes its name from the nearby headland ''Kettle Ness'', but the hamlet is stylised as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plesiosauria
The Plesiosauria (; Greek: πλησίος, ''plesios'', meaning "near to" and ''sauros'', meaning "lizard") or plesiosaurs are an order or clade of extinct Mesozoic marine reptiles, belonging to the Sauropterygia. Plesiosaurs first appeared in the latest Triassic Period, possibly in the Rhaetian stage, about 203 million years ago. They became especially common during the Jurassic Period, thriving until their disappearance due to the Cretaceous–Paleogene extinction event at the end of the Cretaceous Period, about 66 million years ago. They had a worldwide oceanic distribution, and some species at least partly inhabited freshwater environments. Plesiosaurs were among the first fossil reptiles discovered. In the beginning of the nineteenth century, scientists realised how distinctive their build was and they were named as a separate order in 1835. The first plesiosaurian genus, the eponymous ''Plesiosaurus'', was named in 1821. Since then, more than a hundred vali ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ammonites
Ammonoids are a group of extinct marine mollusc animals in the subclass Ammonoidea of the class Cephalopoda. These molluscs, commonly referred to as ammonites, are more closely related to living coleoids (i.e., octopuses, squid and cuttlefish) than they are to shelled nautiloids such as the living ''Nautilus'' species. The earliest ammonites appeared during the Devonian, with the last species vanishing during the Cretaceous–Paleogene extinction event. Ammonites are excellent index fossils, and linking the rock layer in which a particular species or genus is found to specific geologic time periods is often possible. Their fossil shells usually take the form of planispirals, although some helically spiraled and nonspiraled forms (known as heteromorphs) have been found. The name "ammonite", from which the scientific term is derived, was inspired by the spiral shape of their fossilized shells, which somewhat resemble tightly coiled rams' horns.

Ichthyosaurs
Ichthyosaurs (Ancient Greek for "fish lizard" – and ) are large extinct marine reptiles. Ichthyosaurs belong to the order known as Ichthyosauria or Ichthyopterygia ('fish flippers' – a designation introduced by Sir Richard Owen in 1842, although the term is now used more for the parent clade of the Ichthyosauria). Ichthyosaurs thrived during much of the Mesozoic era; based on fossil evidence, they first appeared around 250 million years ago ( Ma) and at least one species survived until about 90 million years ago, into the Late Cretaceous. During the Early Triassic epoch, ichthyosaurs and other ichthyosauromorphs evolved from a group of unidentified land reptiles that returned to the sea, in a development similar to how the mammalian land-dwelling ancestors of modern-day dolphins and whales returned to the sea millions of years later, which they gradually came to resemble in a case of convergent evolution. Ichthyosaurs were particularly abundant in the Late Triass ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
