Ediacara Hills // are a range of low hills in the northern part of the Flinders Ranges of South Australia, around 650 kilometres (400 mi) north of Adelaide. 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 geological period.
There are other places on earth that have Ediacaran era fossils such as localities in Newfoundland along the Atlantic Ocean side.
There is a settlement named Ediacara in the Ediacara Hills region, but it is small. Due to the placement of the hills with respect to the Goyder Line, there is not much surface water and limited ground water.
There are two separate fossil sites within the region which have been granted heritage protection: the Ediacara Fossil Site - Nilpena is listed on the Australian National Heritage List, while the Ediacara Fossil Reserve Palaeontological Site, 20km to its north, is listed on the South Australian Heritage Register.
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. Earlier Australian sources suggested that the "name ‘Ediacara’ or ‘Idiyakra’ may be derived from an Indigenous term associating it with a place near water."
However, "recent linguistic research has suggested 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 dolostone that forms the centre of the Ediacara syncline."
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."

The name ‘Idiyakra’, or ‘Ediacara’, is Australian Aboriginal in origin and can be traced back to 1859 or a little earlier, when the first white pastoralists took up lands in the far north western Flinders Ranges. Its etymology links it to a place where water is or was present close by or about, either in the sense of the present or extending distantly into past wetter times. As water is synonymous with life in the harsh, arid lands of Australia, it is a fitting name for a time when the first megascopic marine animals evolved. As the records of early surveyors and State Parliamentary records show, the ending of the name sounded as a ‘kra’, ‘ker’, or ‘ka’, and hence the appropriate name of the Period is ‘Ediacaran’ (quoted from R.J.F. Jenkins, unpublished note 2003).line feed character in
