... appearance of a whole group of species, is that of the teleostean fishes, low down, according to Agassiz, in the Chalk period. This group includes the large majority of existing species. But certain Jurassic and Triassic forms are now commonly admitted to be teleostean; and even some palaeozoic forms have thus been classed by one high authority. If the teleosteans had really appeared suddenly in the northern hemisphere at the commencement of the chalk formation, the fact would have ...

... inflata are referable to the Gault. Rocks of Tertiary age are met with at Dombe Grande, Mossamedes and near Loanda. The sandstones with gypsum, copper and sulphur of Dombe are doubtfully considered to be of Triassic age. Recent eruptive rocks, mainly basalts, form a line of hills almost bare of vegetation between Benguella and Mossamedes. Nepheline basalts and liparites occur at Dombe Grande. The presence of gum copal in considerable quantities in ...

... population devoted to horse and cattle raising in close proximity to the teeming urban life of Paris. The eastern lowland of England also can be differentiated economically and historically chiefly according to differences of underlying rocks, Carboniferous, Triassic, Jurassic, chalk, boulder clays, and alluvium, which also coincide often with slight variations of relief.[1045] In Russia the contrast between the glaciated surface of the north and the Black Mould belt of the south makes the only ...

... the southern coast, seemed to me at first almost incredible, impressed as I was with the generally received notions as to the ancient character of the Amazonian deposits, referred by Humboldt to the Devonian, and by Martins to the Triassic period, and considered by all travellers to be at least as old as the Tertiaries. The result, however, confirmed his report, at least so far as the component materials of the formation are concerned; but, as will be seen hereafter, the mode of their deposition, and ...

... is twelve miles north of Hot Springs by a good road which offers somewhat meager attractions to the artist, but is more liberal towards the geologist, and especially so in fine exposures of the gypsum bearing Red Beds of the Triassic. Limited patches of it are also exposed in each of the caves, generally carrying small quantities of selenite, which is crystallized gypsum, or in other words, crystallized sulphate of lime. This brilliant red color is so prominent in portions ...

... roar Of long Silurian storms, and tempests huge Scourging the circuit of Devonian seas; Is whispered in the noiseless mists, the gray Soft drip of clouds about rank fern-forests, Through dateless terms that stored the layered coal; Is uttered hoarse in strange Triassic forms Of monstrous life; or stamped in ice-blue gleams Athwart the death-still ...

... of what percentage of the genera of animals, existing in any formation, lived during the preceding formation, it results that in no case is the proportion less than one-third, or 33 per cent. It is the triassic formation, or the commencement of the mesozoic epoch, which has received the smallest inheritance from preceding ages. The other formations not uncommonly exhibit 60, 80, or even 94 per cent, of genera in common with those whose remains are imbedded in their predecessor. Not only is this true, ...

... this: Fishes, including the great whales, and birds; after them, all varieties of terrestrial animals except birds. Nothing could be further from the facts as we find them; we know of not the slightest evidence of the existence of birds before the Jurassic, or perhaps the Triassic, formation; while terrestrial animals, as we have just seen, occur in ...
