what is a earth mound?

Answer 1

In my country, they are called "sambaqui" Sambaqui ( tupi language tamba'kï; literally "mound of shells").

They are human deposits of organic, limy materials, piled up to the long one of the time and suffering the action from weather, that it finishes for promoting a chemical fossilization, therefore deformed rain the structures of the clams and them embedded bones, spreading out calcium in all the structure and petrifying the there existing debris and skeletons.

Silbury Hill, part of the complex of Neolithic monuments around Avebury in Wiltshire (which includes the West Kennet long barrow), is the tallest prehistoric man-made mound in Europe and one of the world's largest. On a base covering over 2 hectares (5 acres), it rises 39.6m (130ft) high. It is a display of immense technical skill and prolonged control over labour and resources. Archaeologists calculate that Silbury Hill was built about 4600 years ago and that it took 18 million man-hours to dump and shape 248,000 cubic metres (8.75 million cu ft) of earth on top of a natural hill. Every man, woman and child in Britain today could together build such a mound if they each contributed one bucketful of earth.
