60:3.1 The great [http://en.wikipedia.org/wiki/Cretaceous Cretaceous] period derives its name from the predominance of the prolific chalk-making [http://en.wikipedia.org/wiki/Foraminifera foraminifers] in the seas. This period brings [[Urantia]] to near the end of the long [[Reptiles|reptilian] [[dominance]] and [[witnesses]] the [[appearance]] of flowering [[plants]] and [http://en.wikipedia.org/wiki/Birds bird] life on land. These are also the times of the termination of the westward and southward [http://en.wikipedia.org/wiki/Continental_drift drift of the continents], accompanied by tremendous [http://en.wikipedia.org/wiki/Earth%27s_crust crustal] deformations and concomitant widespread [http://en.wikipedia.org/wiki/Lava lava] flows and great [http://en.wikipedia.org/wiki/Volcanoes volcanic] activities.

60:3.2 Near the close of the [http://nordan.daynal.org/wiki/index.php?title=Paper_60_-_Urantia_During_Early_Land-Life_Era#60:2._THE_LATER_REPTILIAN_AGE preceding geologic period] much of the [http://en.wikipedia.org/wiki/Continents continental] [[land]] was up above [[water]], although as yet there were no mountain peaks. But as the [[http://en.wikipedia.org/wiki/Continental_drift continental land drift] continued, it met with the first great obstruction on the deep floor of the [[http://en.wikipedia.org/wiki/Pacific_ocean Pacific]. This [[contention]] of geologic [[forces]] gave impetus to the formation of the whole vast north and south mountain range extending from Alaska down through Mexico to Cape Horn.[http://en.wikipedia.org/wiki/Pacific_Ring_of_Fire]

60:3.3 This period thus becomes the modern [[mountain]]-building [[stage]] of [[geologic]] [[history]].[http://en.wikipedia.org/wiki/Orogeny] Prior to this time there were few mountain [[Summit|peaks]], merely elevated land ridges of great width. Now the Pacific coast range was beginning to elevate, but it was located seven hundred miles west of the [http://en.wikipedia.org/wiki/Western_Cordillera_(North_America)#Geologic_origin present shore line]. The [http://en.wikipedia.org/wiki/Sierras Sierras] were beginning to form, their gold-bearing [http://en.wikipedia.org/wiki/Quartz quartz] strata being the product of lava flows of this [[epoch]]. In the [http://en.wikipedia.org/wiki/Geology_of_the_Appalachians eastern part of North America], Atlantic sea pressure was also working to cause [[land]] elevation.

60:3.4 100,000,000 years ago the North American continent and a part of Europe were well above water. The warping of the American continents continued, resulting in the [[metamorphosing]] of the South American [[http://en.wikipedia.org/wiki/Andes_Mountains Andes] and in the gradual elevation of the [http://en.wikipedia.org/wiki/Western_plains#Geology western plains of North America]. Most of [http://en.wikipedia.org/wiki/Geology_of_Mexico Mexico] sank beneath the sea, and the southern Atlantic encroached on the eastern coast of South America, eventually reaching the present shore line. The Atlantic and Indian Oceans were then about as they are today.

60:3.5 95,000,000 years ago the American and European land masses again began to sink. The southern seas commenced the [http://en.wikipedia.org/wiki/File:US_cretaceous_general.jpg invasion of North America] and gradually extended northward to connect with the [http://en.wikipedia.org/wiki/Arctic_Ocean Arctic Ocean], constituting the second greatest submergence of the continent. When this sea finally withdrew, it left the continent about as it now is. Before this great submergence began, the eastern [http://en.wikipedia.org/wiki/Geology_of_the_Appalachians Appalachian highlands] had been almost completely worn down to the [[water]]'s level. The many colored layers of pure clay now used for the manufacture of earthenware were laid down over the Atlantic coast regions during this age, their average thickness being about 2,000 feet.
