The Givetian is one of two faunal stages in the Middle Devonian period. It lasted from 387.7 ± 0.8 million years ago to 382.7 ± 1.6 million years ago. It was preceded by the Eifelian stage and followed by the Frasnian stage. It is named after the town of Givet in France.
The Givetian stage was proposed in 1879 by French geologist Jules Gosselet and was accepted for the higher stage of the Middle Devonian by the Subcommission on Devonian Stratigraphy in 1981.

Taphofacies analysis of late early Givetian fossil assemblages of the Parnaíba Basin (State of Piauí, northeast Brazil) Taphonomic signatures of brachiopod-dominated fossil assemblages from the Passagem Member (Middle Devonian: late early Givetian) are described in the present study. This rock unit (originally assigned to the Cabeças Formation, but actually related to the underlying Pimenteira Formation) is restricted to the eastern border of the Parnaíba Basin. It consists mostly of fine-grained sandstones with sigmoidal clinoform structures (bearing asymptotic cross-stratification and climbing ripples) and interbedded hummocky cross-stratified (HCS) parallel-sided, graded sandstone lobes. Three taphofacies - identified and characterized in four outcrops in the municipalities of Pimentei...

The Ardennes (pronounced /ɑrˈdɛn/; Dutch: Ardennen) is a region of extensive forests, rolling hills and ridges formed within the Givetian (Devonian) Ardennes mountain range[1], primarily in Belgium and Luxembourg, but stretching into France (lending its name to the Ardennes département and the Champagne-Ardenne région), and geologically into the Eifel. In Wallonia, the word 'Ardenne' in the singular is commonly used for the Belgian part of the region and in the plural for the French one. Ardenne is the origin of the great industrial period of Wallonia, the second of the world (18th, 19th and 20th centuries). In France, the word 'Ardennes' in the plural, together with the definite article, is commonly used to refer to the French Department of that name.

De Ardennen (Frans: Ardenne, Waals: Årdene) vormen een bosrijk laaggebergte in oostelijk België (een groot deel van Wallonië), Noord-Luxemburg en een klein stukje aangrenzend Frankrijk. Het is de westelijke uitloper van het Rijnlands leisteenplateau, een massief van leisteen, waartoe ook de Eifel, Hunsrück en de Taunus behoren. Het gebergte is een overblijfsel van de hercynische orogenese en werd 390 tot 300 miljoen jaar geleden gevormd. The Ardennes (/ɑːrˈdɛn/; Luxembourgish: Ardennen; also known as Ardennes Forest) is a region of extensive forests, rough terrain, rolling hills and ridges formed by the geological features of the Ardennes mountain range and the Moselle and Meuse River basins. Geologically, the range is a western extension of the Eifel and both were raised during the Giveti...
In this video you are travelling with me on a journey from France to Netherlands in October 2009. The title: Long long journey... , is not really counting for this journey. Though it lasts more than ten hours to travel from France to Netherlands, travelling by train is very relaxing and exciting at the same time, reason for why these hours go as fast as the high speed of the luxurious trains. The new French trains are fast, very very modern and comfortable! We drive through the Belgian Ardennes, in autumn: the trees have been coloured into warm red, orange and yellow ocher, and some have already lost all the leafs. On some moments you see "nothing" but some shrubs flashing by because of the high speed of the train, and because they are so close next to the rail road, or layers of the Ard...
The Ardennes (/ɑrˈdɛn/; Luxembourgish: Ardennen; also known as Ardennes Forest) is a region of extensive forests, rough terrain, rolling hills and ridges formed by the geophysical features of the Ardennes mountain range and the Moselle and Meuse River basins. Geologically, the range is a western extension of the Eifel and both were raised during the Givetian stage, of the Devonian (419.2 ± 3.2 to about 358 Mya (million years ago)) as were several other named ranges of the same greater range. Primarily in Belgium and Luxembourg, but stretching into Germany and France (lending its name to the Ardennes department and the Champagne-Ardenne région), and geologically into the Eifel—the eastern extension of the Ardennes Forest into Bitburg-Prüm, Germany, most of the Ardenne proper consists of sou...

Two children from the future travel to ancient times to witness major events in religious history.
The Devonian is a geologic period and system of the Paleozoic Era spanning from the end of the Silurian Period, about 419.2 ± 3.2 Mya (million years ago), to the beginning of the Carboniferous Period, about 358.9 ± 0.4. It is named after Devon, England, where rocks from this period were first studied. The Devonian period experienced the first significant adaptive radiation of terrestrial life. Free-sporing vascular plants began to spread across dry land, forming extensive forests which covered the continents. By the middle of the Devonian, several groups of plants had evolved leaves and true roots, and by the end of the period the first seed-bearing plants appeared. Various terrestrial arthropods also became well-established. Fish reached substantial diversity during this time, leading the...
