More "Silurian" Quotes from Famous Books
 ... India, 1st ed., Part I, p. iv). The Satpura range, thus defined, separates the valley of the Nerbudda from the valleys of the Tapti flowing west, and the Mahanadi flowing east. The Vindhyan sandstones certainly are a formation of immense antiquity, perhaps pre-Silurian. They are azoic, or devoid of fossils; and it is consequently impossible to determine exactly their geological age, or 'horizon' (ibid. p. xxiii). The cappings of basalt, in some cases with laterite superimposed, suggest ...

... the Midlands, because they now consist almost entirely of the descendants of the free Britons who were driven westward rather than submit to the overwhelming invasion of the Teutonic tribes. Thus it is that probably, except for a certain Silurian (or Iberian) element in South Wales, which descends from the higher or fighting sort of pre-Aryan, and a surviving aboriginal element in parts of Ireland, the natives of what are known as the “Celtic” parts of these islands are more purely Aryan than any except the ...

... thence through boreal and arctic latitudes into North America. Of the height and mass of this primeval land some idea may be formed by considering the enormous bulk of the material derived from its disintegration. In the Silurian formations of the British Islands alone there is a mass of rock, worn from the land, which would form a mountain-chain extending from Marseilles to the North Cape (1800 miles), with a mean breadth of over thirty-three miles, and an average ...
— The Antediluvian World • Ignatius Donnelly
... as it was at first, there was not a living plant or animal; after thousands of years, or millions of years, there came into the broad seas of the lower Silurian epoch, some of the lowest kinds of animals and seaweeds, a few trilobites and mollusks, but no plants save fucoids. Next came, after a long time, a few cartilaginous fishes and corals. A long time passed—thousands ...

... one other geological term, bequeathed to us by a great authority, and which cannot be changed for the better: I mean that of Geological Horizon, applied by Humboldt to the whole extent of any one geological division,—as, for instance, the Silurian horizon, including the whole extent of the Silurian epoch. It indicates one level in time, as the horizon which limits our view indicates the farthest extension of the plain on which we stand ...

... the European and of the North American Silurians based? In the last edition of Sir Charles Lyell's "Elementary Geology" it is stated, on the authority of a former President of this Society, the late Daniel Sharpe, that between 30 and 40 per cent. of the species of Silurian Mollusca are common to both sides of the Atlantic. By way of due allowance for further discovery, let us double the lesser number and suppose that 60 per cent. of the species are common to the North American and the British Silurians. Sixty per cent. of species in common ...

... associations of ideas 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 by desire for food or mate. Life was not able to maintain ...

The same in language. Unless some languages had been arrested in their growth during their earlier stages, and had remained on the surface in this primitive state exposed only to the decomposing influence of atmospheric ...

... the Slob Works a low range of corrugated iron shedding shines out suddenly through a break in the vapour, and, as the sun again pierces through, a long, low, dark line is seen stretching from the shore into the water like the extremity of some huge saurian of the Silurian period reposing on his native slime and ooze. But the lengthy monster lying in a vast curve is not at peace, for on the jagged ridge of his mighty back a puffing, snorting, smoking plague perpetually runs up and down. The apparent plague, however, is really increasing the size of the ...

... 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 he said ...

... the epicentral district is covered by a sheet of Old Red Sandstone (Fig. 64), but, just to the north-east of the position laid down for the originating fault (indicated by the straight broken line), is the well-known Woolhope anticlinal, by which Silurian beds are brought to the surface. The anticlinal axis runs approximately north-west and south-east, and is thus roughly parallel to the earthquake-fault. Moreover, the thinning-out and occasional disappearance of some of the Silurian beds on the south-west side of the anticlinal ...

... requires that the first form which existed of each of the great divisions would present points intermediate between existing ones, but immensely different. Most geologists believe Silurian{117} fossils are those which first existed in the whole world, not those which have chanced to be the oldest not destroyed,—or the first which existed in profoundly deep seas in progress of conversion from sea to land: if they are first they give up. Not so Hutton ...

... of his life, and to which he himself attached the greatest importance. In Wales he took up the question of the age of the rocks in the neighbourhood of Dolgelly, and after much study of their fossils proposed the now accepted classification of the Lingula flags of the Lower Silurian system into the Maenturog flags and slates, the Festiniog flags, and the Dolgelly slates. The collecting of lepidoptera was his chief amusement in Brazil, where he made his first acquaintance with the teeming life of the torrid zone and laid the foundation ...

... blanks between strata in any particular vertical series are amply filled in with records in the form of thick strata in some geographically distant series. For example, in some regions Silurian rocks are directly overlaid by the coal measures; but elsewhere this sudden break is filled in with the Devonian rocks that tell of a great "age of fishes." So commonly are breaks in the strata in one region filled up in another that we are forced to conclude that the record ...

City Front, despite of piles and pier and wharf, the Pacific tides still asserted themselves in mud and ooze as far as Sansome Street; the wooden sidewalks of Clay and Montgomery streets were mere floating bridges or buoyant pontoons superposed on elastic bogs; Battery Street was the Silurian beach of that early period on which tin cans, packing-boxes, freight, household furniture, and even the runaway crews of deserted ships had been cast away. There were dangerous and unknown depths in Montgomery Street and on the ...

Below this Devonian limestone, its crystals sparkling in the sunshine, with its coral fossils, its fragments of crinoids, and its broken shells of brachiopods, down through the Devonian, the Silurian, the Ordovician, and the Cambrian rocks, down to the original crust formed when first the earth began to cool, if any there be remaining; all these miles of rocks are inorganic, built up of crystals. But here on the surface, the tender green mosses ...

... misled by trusting to lithological evidence; yet his reasoning all through Siluria, shows that he still thinks it natural to expect formations of the same age to be chemically similar, even in remote regions. For example, in treating of the Silurian rocks of South Scotland, he says:—"When traversing the tract between Dumfries and Moffat, in 1850, it occurred to me, that the dull reddish or purple sandstone and schist to the north of the former town, which so resembled the bottom rocks of Longmynd, Llanberis, and St. David's, would prove ...

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 and are yet to be, he is thereby not warranted to extend his ...

... 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 colonisation of Saskatchewan would be assured if the current objection to the severity ...

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 ...

... 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 ...

... 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 ...

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 ...

... 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 ...
