Which range in France and Switzerland gives its name to the Jurassic Period?

The Jura Mountains, along the France–Switzerland border, gave their name to the Jurassic Period.

The Jura is a sub-Alpine limestone range lying northwest of the Alps. Its folded core runs mainly through France and western Switzerland, while related Table Jura formations continue northeastward into Switzerland and southern Germany. Crêt de la Neige, in France, is its highest summit at about 1,720 metres.

The geological connection began with studies of the range’s distinctive limestone. In 1795, Alexander von Humboldt examined Jura rocks and later called them Jura-Kalkstein, or “Jura limestone.” In 1829, Alexandre Brongniart used the French term terrains jurassiques when correlating these rocks with similarly aged strata elsewhere, establishing the period’s name. The Jurassic was a geological period of the Mesozoic Era, following the Triassic and preceding the Cretaceous. The range is not the Alps, although it lies immediately north of them and reflects Alpine mountain building.
