But the story is told swiftly and clearly; the players, most of them peasants the director discovered in Orgosolo, bring to their roles a pithecanthropic power that few actors could suggest; and the landscape of Sardinia is astonishing, a scene of Pre-Cambrian catastrophe. On every side great ridges of bare rock burst out of the earth, leap up to the sky, fall back in fragments. Seen from a summit, the whole island resembles a titanic skeleton over which man wanders like...
...theory further, Dombrowski is examining salt from even older beds. Last month the University of Montreal sent him samples from Saskatchewan deposits that are 320 million years old. In 20 experiments he found eight strains of living bacteria. Now he has broadcast a worldwide appeal for samples of pre-Cambrian salt 750 million years old, hopeful that he can find still more primitive germs...
...Four other companies (Copper Cliff Consolidated Mining Corp., New Royran Copper Mines Ltd., Chibougamau Jaculet and Copper Rand) around the rim of Dore Lake are shooting for production next year. The investment already totals $50 million. Dotted over the lonely countryside, some 100 drilling crews are probing the Pre-Cambrian rocks for new deposits or extensions of established finds.

During the summer of 1954, Barghoorn, with two geologist colleagues, uncovered the oldest coal deposits yet discovered. The age of the coal, pre-Cambrian, is of great geological interest as it carries back the fossil record of plant life to over a billion years...
...plant fossils were taken from a deposit of flint rock in the gunflint formation near Schreiber. Out The two researchers identified their find as "the oldest structurally preserved organisms which have been discovered in pre-Cambrian sediments." They are "of great theoretical interest in the evolutionary scheme of primitive life...
