Ediacara Hills /iːdiːˈækərə/ are a range of low hills in the northern part of the Flinders Ranges of South Australia, around 650 kilometres (400 mi) north of the state capital of Adelaide. The hills are known for being the location of significant fossils, and have given their name to the geological period known as the Ediacaran.

Description

The area has many old copper and silver mines from mining activity during the late 19th century. The hills also contain fossils of early multicellular life forms, the Ediacaran biota (lagerstätte), and have given their name to the Ediacaran.[1][2]

There are two separate fossil sites within the region which have heritage protection: The Ediacara Fossil Site – Nilpena is listed on the Australian National Heritage List, while the Ediacara Fossil Reserve Palaeontological Site which is located 20 kilometres (12 mi) to its north is listed on the South Australian Heritage Register.[3][4]

There is a settlement named Ediacara in the Ediacara Hills region, but it is small.^{[citation needed]} Due to the placement of the hills with respect to the Goyder Line, there is not much surface water and limited ground water.^{[clarification needed]}

Word origin

The name "Ediacara" has a disputed origin from one of the Aboriginal languages near the Flinders Range area. It is first known to have been used during the middle of the 19th century.[5][6] Earlier Australian sources suggested that the "name "Ediacara" or "Idiyakra" may be derived from an Indigenous term associating it with a place near water".[7][lower-alpha 1]

Another theory suggests that the term may be a mispronunciation of the two words "Yata Takarra", meaning hard or stony ground ("in reference to the flat Ediacara plateau of dolomite that forms the centre of the Ediacara syncline").[9] Supporting this latter contention, it has been argued that the word "has nothing in it that corresponds to any word for water in any of the local languages" and that local tradition "has it that the name meant 'granite plain', but, since there appears to be no igneous rock in the area, this could well refer to the hardness of the ground, rather than to its geological composition".[5]

However, there are a number of complications in trying to establish the origins of place names supposedly relating to Aboriginal words, and there is no definitive answer for Ediacara.[10]

[de] Ediacara-Hügel

Die Ediacara-Hügel sind eine Hügelkette im Nordwesten des Flindersgebirges im australischen Bundesstaat South Australia rund 450 km nördlich von Adelaide. In dieser Region wurden 1946 die ersten Spuren mehrzelliger Tiere aus dem Präkambrium in Form fossiler Abdrücke gefunden.[1] Diese Lebewesen, die noch keine erhaltungsfähigen Hartteile entwickelt hatten und deren systematische Stellung bislang ungeklärt ist, werden zusammenfassend als Ediacara-Fauna bezeichnet.

[ru] Эдиакары (горы)

Эдиакарские горы[источник не указан 1216 дней] (или Эдиакарские холмы, от англ. Ediacara Hills)— гряда невысоких холмов в северной части хребта Флиндерс в 650 км к северу от Аделаиды. С конца XIX века — территория интенсивной добычи меди и серебра. Известны геологическими отложениями позднего докембрия, где впервые обнаружены следы докембрийских многоклеточных организмов, названных впоследствии эдиакарской биотой. По названию гор назван эдиакарский (вендский) геологический период, последний период протерозойской эры[1][2].
