Continental Island


ektas (ektasis - extension, extension) - middle period of Mesoproterozoic; lasted from 1.4 to 1.2 billion years ago. From that period came the rock formation geological Hunting on Somerset Island (Canada). During its existence lived the oldest known multicellular organisms and the oldest known reproductive organisms. Ektas is younger than calim and older than stenu. Such an island is eg Madagascar. Islands such as Tasmania and New Guinea, located on the continental shelf of Australia, divide from the mainland of the shelf sea, which have retreated during the low levels of World Ocean waters, exposing the dry land.
