"Silurian" Quotes from Famous Books
... the evolution of the human no less than the lower animal races out of some simple primordial animal,—that all are equally "lineal descendants of sense few beings which lived long before the first bed of the Silurian system was deposited." But, as the author speaks disrespectfully of spontaneous generation, and accepts a supernatural beginning of life on earth, in some form or forms of being which included potentially all that have since existed ... — Atlantic Monthly Vol. 6, No. 33, July, 1860 • Various
... "that the basalt monadnock on which we stand is a carboniferous upthrust of metamorphosed schists, shales and conglomerate, probably Mesozoic or at least early Silurian." ... — The Cruise of the Kawa • Walter E. Traprock
... Canada and the States was the first American land lifted above the ocean. That land belongs to the Azoic period, and contains no trace of life. Along the base of that range of hills lie the deposits of the next great geological period, the Silurian; and the State of New York, geologically speaking, belongs almost entirely to this Silurian period, with its lowest Taconic division, and the Devonian period, the third in succession of these great epochs. I need hardly remind those of my readers ... — The Atlantic Monthly, Vol. IX., March, 1862., No. LIII. - A Magazine Of Literature, Art, And Politics, • Various
... glimpse of him half an hour ago; but before I could escape from a geologist who was boring me about the Silurian system, Kenelm ... — Kenelm Chillingly, Complete • Edward Bulwer-Lytton
... hillock which rose a couple of metres above the surrounding plain. The plain terminated towards the sea with a steep escarpment. The land was even, but rose gradually to a height of eighteen metres above the sea. The country consisted of upright strata of Silurian limestone running from east to west, and at certain places containing fossils resembling those of Gotland. Here and there were shallow depressions in the plain, covered with a very rich and uniformly green growth of grass. The high-lying ... — The Voyage of the Vega round Asia and Europe, Volume I and Volume II • A.E. Nordenskieold
... any truth in the doctrine of evolution, every class must be vastly older than the first record of its appearance upon the surface of the globe. But if considerations of this kind compel us to place the origin of vertebrated animals at a period sufficiently distant from the Upper Silurian, in which the first Elasmobranchs and Ganoids occur, to allow of the evolution of such fishes as these from a Vertebrate as simple as the Amphioxus, I can only repeat that it is appalling to speculate upon the extent to which that origin must have preceded ... — Critiques and Addresses • Thomas Henry Huxley
... of the forms we have hitherto considered. Forms closely related to it occur among the earliest remains of vertebrata that are to be found in the geological record. Since the immeasurably remote Silurian period, sharks and dog-fish have probably remained without any essential changes of condition, and consequently without any essential changes of structure, down to the present day. Then, as now, they dominated the seas. They probably branched off from the other vertebrata ... — Text Book of Biology, Part 1: Vertebrata • H. G. Wells
... the maddest geologist under such circumstances would have studied the nature of the rocks that we were passing. I am sure I did trouble my head about them. Pliocene, miocene, eocene, cretaceous, jurassic, triassic, permian, carboniferous, devonian, silurian, or primitive was all one to me. But the Professor, no doubt, was pursuing his observations or taking notes, for in one of our halts ... — A Journey to the Interior of the Earth • Jules Verne
... this continent, north-west of Minnesota, and known as the Saskatchewan district, is estimated by English authorities to comprise 368,000 square miles. North-west from Otter Tail Lake, the geographical centre of Minnesota, extends a vast silurian formation, bounded on the west along the eastern base of the Rocky Mountains by coal measures. Such a predominance of limestone implies fertility of soil, as in the north-western States, and the speedy ... — Handbook to the new Gold-fields • R. M. Ballantyne
... and the forming of new relations - a simple matter were it not for our mental inertia. Lester Ward speculates that life remained aquatic for the vast periods that paleontology would indicate; Cambrian, Silurian, Devonian, Carboniferous - a duration greater than all subsequent time - for the reason that the creature had not progressed beyond the stage when it could move otherwise than in a straight line when actuated ... — The Fourth Dimensional Reaches of the Panama-Pacific International Exposition • Cora Lenore Williams
... according to their relative age, into three great groups, known respectively as the primary, secondary, and tertiary periods. In the secondary period we do not appear to meet with the fuels of the future, but as far back as the Devonian or old Red Sandstone period, and in the still older Silurian rocks, stores of gas and petroleum abound. In the latest or tertiary period, again, we come upon nearly all the forms of fuels we have ... — Scientific American Supplement, No. 717, September 28, 1889 • Various
... understand our possible knowledge of the early world and its inhabitants, we must compare, not the area of the whole field of our geological researches with the earth's surface, but the area of the examined portion of each formation separately with the whole earth. For example, during the Silurian period all the earth was Silurian, and animals were living and dying, and depositing their remains more or less over the whole area of the globe, and they were probably (the species at least) nearly as varied in different latitudes ... — Contributions to the Theory of Natural Selection - A Series of Essays • Alfred Russel Wallace
... yet in a chaotic and formative condition; huge slides of Silurian slates and diorite are of frequent occurrence. A ridge of one of these softer stones had most probably been encased in the surrounding granite for many centuries; then, loosened by water or by time, had crumbled and slid ... — Under the Andes • Rex Stout
... said of other organic divisions. It has gone to record that the shell-fish of the Silurian system are the lowest division of the molluscous animals. While the statement is received as true, it must be remembered that there is some diversity of structure in this lower division, and that the earliest molluscs are not the lowest, but the highest in the division. ... — The Christian Foundation, Or, Scientific and Religious Journal, Volume I, No. 7, July, 1880 • Various
... are carved from the Silurian limestone, although they are considered to date from the Tertiary period. Long after the cave was formed, and after many stalactites had been hung on those spacious halls with their down-grown crystals, it was completely filled with glacial mud charged with acid, whereby the dripstones ... — See America First • Orville O.

... seem, somehow, to be fully persuaded that the inspired word of God has no inherent power to stand alone,—that it has fallen among thieves and robbers,—is being pelted with fossil coprolites, suffocated with fire-mist and primitive gases, or beaten over the head with the shank-bones of Silurian monsters, and is bawling aloud for assistance. Therefore, not stopping to dress, they dash out into the public notice without hat or coat, in such unclothed intellectual condition as they happen to be in,—in ... — Atlantic Monthly, Volume 6, Issue 35, September, 1860 • Various
... road went through a place called absurdly enough Paris, from the quantity of gypsum with which the neighbourhood abounds; and fine specimens of silurian fossils of the trilobite family and of madrepores, millepores, and corallics, are found here. Love's Hotel is the best in the village, and a good one ... — Canada and the Canadians, Vol. 2 • Richard Henry Bonnycastle
... had time and space to describe some of the beautiful bacteria and gigantic worms that formerly inhabited the earth. Such an aggregation of actual, living Silurian monsters, any one of which would make a man a fortune to-day, if it could be kept on ice and exhibited for one season only. You could take a full grown mastodon to-day, and with no calliope, no lithographs, ... — Remarks • Bill Nye |
