58:7.5 The [http://en.wikipedia.org/wiki/Rock_%28geology%29 rocks] of this [[era]] are [[exposed]] here and there all over the world, but none are so easy of [[interpretation]] as those about [http://en.wikipedia.org/wiki/Lake_Superior Lake Superior] and in the [http://en.wikipedia.org/wiki/Grand_Canyon Grand Canyon] of the [http://en.wikipedia.org/wiki/Colorado_river Colorado River], where these [[primitive]] [[fossil]]-bearing rocks, existing in several layers, testify to the [[upheavals]] and [[surface]] fluctuations of those faraway times.

58:7.6 This stone layer, the oldest [[fossil]]-bearing [http://en.wikipedia.org/wiki/Stratigraphy stratum] in the [http://en.wikipedia.org/wiki/Earth%27s_crust crust]] of the [[earth]], has been crumpled, folded, and grotesquely twisted as a result of the [[upheavals]] of [[http://en.wikipedia.org/wiki/Earthquakes earthquakes] and the early [http://en.wikipedia.org/wiki/Volcanoes volcanoes]. The [[http://en.wikipedia.org/wiki/Lava lava] [[flows]] of this [[age]] brought much [http://en.wikipedia.org/wiki/Iron iron], [http://en.wikipedia.org/wiki/Copper copper], and [http://en.wikipedia.org/wiki/Lead lead] up near the [[planetary]] [[surface]].

58:7.7 There are few places on the [[earth]] where such [[activities]] are more graphically shown than in the [http://en.wikipedia.org/wiki/St._Croix_Valley St. Croix valley] of [http://en.wikipedia.org/wiki/Wisconsin Wisconsin]. In this region there occurred one hundred and twenty-seven [[successive]] [http://en.wikipedia.org/wiki/Lava lava flows] on [[land]] with succeeding [[water]] submergence and consequent [http://en.wikipedia.org/wiki/Rock_%28geology%29 rock deposition]. Although much of the upper rock sedimentation and intermittent [http://en.wikipedia.org/wiki/Lava lava flow] is absent today, and though the bottom of this [[system]] is buried deep in the [[earth]], nevertheless, about sixty-five or seventy of these [http://en.wikipedia.org/wiki/Stratigraphy stratified] [[records]] of past ages are now [[exposed]] to view.

58:7.9 During these times of [[primitive]] [[marine]] life, extensive areas of the [http://en.wikipedia.org/wiki/Continents continental] shores sank beneath the seas from a few feet to half a mile. Much of the older [http://en.wikipedia.org/wiki/Sandstone sandstone] and conglomerates [[represents]] the sedimentary accumulations of these ancient shores. The sedimentary rocks belonging to this early [http://en.wikipedia.org/wiki/Stratigraphy stratification] rest directly upon those layers which date back far beyond the [[origin]] of life, back to the early [[appearance]] of the [http://nordan.daynal.org/wiki/index.php?title=Paper_57#57:8._CRUSTAL_STABILIZATION-THE_AGE_OF_EARTHQUAKES-THE_WORLD_OCEAN_AND_THE_FIRST_CONTINENT world-wide ocean].

58:7.10 Some of the upper layers of these [[transition]] [http://en.wikipedia.org/wiki/Rock_%28geology%29 rock] deposits contain small amounts of [http://en.wikipedia.org/wiki/Shale shale] or [http://en.wikipedia.org/wiki/Slate slate] of dark [[colors]], indicating the [[presence]] of organic http://en.wikipedia.org/wiki/Carbon carbon] and testifying to the [[existence]] of the [[ancestors]] of those [[forms]] of [[plant]] life which overran the [[earth]] during the succeeding [http://en.wikipedia.org/wiki/Carboniferous Carboniferous] or coal age. Much of the [http://en.wikipedia.org/wiki/Copper copper] in these rock layers results from [[water]] deposition. Some is found in the cracks of the older rocks and is the [[concentrate]] of the sluggish swamp water of some ancient sheltered shore line. The [http://en.wikipedia.org/wiki/Iron iron] mines of [http://en.wikipedia.org/wiki/North_America North America] and [http://en.wikipedia.org/wiki/Europe Europe] are located in deposits and extrusions lying partly in the older unstratified rocks and partly in these later [http://en.wikipedia.org/wiki/Stratigraphy stratified rocks] of the [[transition]] periods of life formation.

58:7.11 This [[era]] [[witnesses]] the spread of life throughout the [[waters]] of the world; [[marine]] life has become well [[established]] on [[Urantia]]. The bottoms of the shallow and extensive inland seas are being [[gradually]] overrun by a profuse and [[luxuriant]] [[growth]] of [[Plant|vegetation]], while the shore-line [[waters]] are swarming with the [[simple]] [[forms]] of [[animal]] life.
