Tremadocian
The Tremadocian is the lowest stage of Ordovician. Together with the later Floian Stage it forms the Lower Ordovician Epoch. The Tremadocian lasted from to million years ago. The base of the Tremadocian is defined as the first appearance of the conodont species ''Iapetognathus fluctivagus'' at the Global Boundary Stratotype Section and Point (GSSP) section on Newfoundland. Naming The Tremadocian is named after the village Tremadoc in Wales. The name was proposed by Adam Sedgwick in 1846 (as "Tremadoc group"). GSSP The GSSP for the beginning of the Tremadocian is the Greenpoint section () in Gros Morne National Park, in western Newfoundland. It is defined as the first appearance of the conodont species ''Iapetognathus fluctivagus''. This horizon can be found 101.8 m above the Greenpoint section datum within bed number 23. The boundary lies within the Broom Point Member, of the Green Point Formation which is part of the Cow Head Group. The first planktonic graptolites appear 4.8 ...

Gwynedd
Gwynedd (; ) is a county and preserved county (latter with differing boundaries; includes the Isle of Anglesey) in the north-west of Wales. It shares borders with Powys, Conwy County Borough, Denbighshire, Anglesey over the Menai Strait, and Ceredigion over the River Dyfi. The scenic Llŷn Peninsula and most of Snowdonia National Park are in Gwynedd. Bangor is the home of Bangor University. As a local government area, it is the second largest in Wales in terms of land area and also one of the most sparsely populated. A majority of the population is Welsh-speaking. ''Gwynedd'' also refers to being one of the preserved counties of Wales, covering the two local government areas of Gwynedd and Anglesey. Named after the old Kingdom of Gwynedd, both culturally and historically, ''Gwynedd'' can also be used for most of North Wales, such as the area that was policed by the Gwynedd Constabulary. The current area is , with a population of 121,874 as measured in the 2011 Census. Et ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Penrhyndeudraeth
Penrhyndeudraeth (; ) is a small town and community in the Welsh county of Gwynedd. The town is close to the mouth of the River Dwyryd on the A487 nearly east of Porthmadog, and had a population of 2,150 at the 2011 census, increased from 2,031 in 2001. The community includes Minffordd and Portmeirion. History An older settlement of a few cottages at Upper Penrhyn was originally called ''Cefn Coch'' ('Red Ridge') and that name is perpetuated by the Penrhyndeudraeth primary school, which is known as Ysgol Cefn Coch; but the town proper is comparatively modern. The ground on which it stands was a malarial swamp encircling a huge stagnant pool. The present town owes its existence as a commercial centre to a local landowner, David Williams of Castell Deudraeth near Minffordd, who in the mid-19th century drained the swamp and dried the pool and constructed many streets. Adopting a scheme of town planning evolved by the builder of Tremadog and his Italian craftsmen, Williams gave P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North West Wales
North West Wales ( cy, Gogledd-Orllewin Cymru) refers to an area or region of Wales, commonly defined as a grouping of the principal areas of Conwy County Borough, Gwynedd and the Isle of Anglesey in the north-west of the country. These principal areas make up the entire preserved county of Gwynedd, and parts of Clwyd. It is bordered by Denbighshire, in North East Wales to the east, Powys, and Ceredigion in Mid Wales to the south, and the Irish sea to the north and west (as Cardigan Bay). It is the more mountainous, rural, and sparsely populated part of the north Wales geographic region. Settlements include: Bangor, Caernarfon, Colwyn Bay, Holyhead, Llandudno, and Pwllheli. The port of Holyhead serves as the major sea link between Wales and the Republic of Ireland. Snowdonia National Park is located wholly in the area, hosting Snowdon, the largest peak in Britain and Ireland excluding the Scottish Highlands. The area also hosts AONBs (Area of Outstanding Natural Beauty) in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Porthmadog
Porthmadog (; ), originally Portmadoc until 1974 and locally as "Port", is a Welsh coastal town and community in the Eifionydd area of Gwynedd and the historic county of Caernarfonshire. It lies east of Criccieth, south-west of Blaenau Ffestiniog, north of Dolgellau and south of Caernarfon. The community population of 4,185 in the 2011 census was put at 4,134 in 2019. It grew in the 19th century as a port for local slate, but as the trade declined, it continued as a shopping and tourism centre, being close to Snowdonia National Park and the Ffestiniog Railway. The 1987 National Eisteddfod was held there. It includes nearby Borth-y-Gest, Morfa Bychan and Tremadog. History Porthmadog came about after William Madocks built a sea wall, the ''Cob'', in 1808–1811 to reclaim much of Traeth Mawr from the sea for farming use. Diversion of the Afon Glaslyn caused it to scour out a new natural harbour deep enough for small ocean-going sailing ships,John Dobson and Roy Woods, ''Ffe ...

Paradoxides
''Paradoxides'' is a genus of large to very large trilobite found throughout the world during the Middle Cambrian period. One record-breaking specimen of ''Paradoxides davidis'', described by John William Salter in 1863, is . The cephalon was semicircular with free cheeks ending in long, narrow, recurved spines. Eyes were crescent shaped providing an almost 360° view, but only in the horizontal plane. Its elongate thorax was composed of 19-21 segments and adorned with longish, recurved pleural spines. Its pygidium was comparatively small. ''Paradoxides'' is a characteristic Middle-Cambrian trilobite of the 'Atlantic' (Avalonian) fauna. Avalonian rocks were deposited near a small continent called Avalonia in the Paleozoic Iapetus Ocean. Avalonian beds are now in a narrow strip along the East Coast of North America, and in Europe. Description The exoskeleton of ''Paradoxides'' is large to very large, relatively flat, and about one and a half times longer than wide, with greate ...

Trilobite
Trilobites (; meaning "three lobes") are extinct marine arthropods that form the class Trilobita. Trilobites form one of the earliest-known groups of arthropods. The first appearance of trilobites in the fossil record defines the base of the Atdabanian stage of the Early Cambrian period () and they flourished throughout the lower Paleozoic before slipping into a long decline, when, during the Devonian, all trilobite orders except the Proetida died out. The last extant trilobites finally disappeared in the mass extinction at the end of the Permian about 252 million years ago. Trilobites were among the most successful of all early animals, existing in oceans for almost 270 million years, with over 22,000 species having been described. By the time trilobites first appeared in the fossil record, they were already highly diversified and geographically dispersed. Because trilobites had wide diversity and an easily fossilized exoskeleton, they left an extensive fossil record. The stu ...

Solva
Solva ( cy, Solfach) is a village, community and electoral ward in Pembrokeshire, Wales. The village comprises principally Lower Solva and Upper Solva. The community also includes Middle Mill and Whitchurch. Location Solva lies on the north side of St Bride's Bay, in North Pembrokeshire in the Pembrokeshire Coast National Park and on the Pembrokeshire Coast Path. It lies on a deep valley at the mouth of the River Solva. In the valley is Lower Solva, consisting of a long street ending at the small harbour. Most of the modern development has been in Upper Solva, on the cliff top to the west of the harbour.
