"Devonian" Quotes from Famous Books



... by the aid of which it is possible to read the story of the past. By careful piecing together of evidence the geologist is able to determine the order in which the different sedimentary rocks were laid down, and thus to say, for instance, that the Devonian period was the time of the origin of Amphibians. In other cases the geologist utilises the fossils in his attempt to work out the order of the strata when these have been much disarranged. For the simpler fossil forms of ...

... outcrop of the early Devonian formation. It was Stalky who had invented his unlovely name. "He was pretty average drunk, or he wouldn't have done it. Rabbits-Eggs is a little shy of me, somehow. But I swore it was pax between us, and gave him a bob. He stopped at two pubs on the ...

... "Recherches sur les Poissons Fossiles" was completed, and fast upon its footsteps, in 1844, followed the author's "Monograph on the Fossil Fishes of the Old Red Sandstone, or the Devonian System of Great Britain and Russia," a large quarto volume of text, accompanied by forty-one plates. Nothing in his paleontological studies ever interested Agassiz more than this curious fauna of the Old Red, so strange in its ...

... history of the world are fishes; fish spines and placoid scales (compare dog-fish) appear in the Ordovician rocks. In the coal measures come the amphibia; and in the Permo-triassic strata, reptile-like mammals. In the Devonian rocks, which come between the Silurian and the coal measures, we find very plentiful remains of certain fish called the dipnoi, of which group three genera still survive; they display, in numberless features of their anatomy, transitional ...

... 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 ...

... fish had been a ganoid—that ancient, armoured form that was perhaps the most intelligent of all life on our planet during the Devonian era, but which for age upon age had vanished, save for its fossils held in the embrace of the stone that once was their soft bottom beds; and the half-globes were Medusae, jelly-fish—but of a size, luminosity, and ...

... the ammonites, taken as a group, is simple and clear; they arose as a branch of the nautiloids in the lower Devonian, the shells known as goniatites having zigzag, angulated sutures. Late in the succeeding Carboniferous period appear shells with a truly ammonoid complexity of sutures, and in the Permian their ...

... geological record, we have at least no evidence that anything bigger as yet moved upon the face of the waters. The trilobites, which were a sort of triple-tailed crabs (to speak very popularly), began in the Cambrian Epoch, attained their culminating point in the Silurian, waned in the Devonian, and died out utterly in ...

... Silurians, now Caerleon-upon-Usk. In the west country, to this day, ask always becomes ax, or rather remains so, for that provincial form was the King's English at the court of Alfred; and so Isca became on Devonian lips Exan ceaster, after the West Saxon conquest. Thence it passed rapidly through the stages of Exe ceaster and Exe cester till it finally settled down into Exeter. At the same time, the river itself became the Exe; and the Exan-mutha of the Chronicle dropped into Exmouth. We must never forget, ...

... the two types are each too specialized to lead us to suppose that one was derived from the other. Moreover, we find through the researches of Messrs. Hartt and Scudder that there were highly developed insects, such as May flies, grasshoppers, etc., in the Devonian rocks of New Brunswick, leading us to expect the discovery of low insects even in the Upper Silurian rocks. At any rate this discovery pushes back the origin of insects beyond a time when there were true Zoeae, as the shrimps and their allies are not actually known to exist ...

... know, absolutely the most ancient,—belonged to a ganoid as bulky as a large porpoise, and which, as shown by its teeth and jaws, possessed that peculiar organization which characterized the reptile fish of the Upper Devonian and Carboniferous periods. As there are, however, no calculations more doubtful or more to be suspected than those on which the size and bulk of the extinct animals are determined from some surviving ...

... Heard the rasp of a boat-hook along the wire-rope, and then, as it had been in my ear, Pyecroft's enormous and jubilant bellow astern: "Why, he's here! Right atop of us! The blighter 'as pouched half the tow, like a shark!" A long pause filled with soft Devonian bleatings. Then Pyecroft, solo arpeggie: "Rum? Rum? Rum? Is that all? Come an' try ...
