There has been no time since rocks now in existence were formed, if ever, when the earth had a uniform climate and a single undiversified fauna over its entire land surface, as the early paleontologists supposed.
From later observation I mention this as worthy the attention of paleontologists and naturalists I came to the conclusion that such creatures as the cave-bear, the cave-lion and the saber-tooth tiger, as well as the larger carnivorous reptiles make, ordinarily, two kills a day one in the morning and one after night.
Our paleontologists are opening layer after layer of these rocks, and thus examining each year new pages in nature's history. The more recent epochs in the history have been already read with almost historic accuracy.
"The paleontologists say that he was herbivorous," said Tarzan as he and Jane approached the beast. The journey to Ja-lur was made through the scattered villages where Ja-don hoped to arouse a keener enthusiasm for his cause. A party of warriors preceded Tarzan that the people might properly be prepared, not only for the sight of the gryf but to receive the Dor-ul-Otho as became his high station.
In modern times John Dalton, the discoverer of the atomic theory of colorblindness, was born of Quaker parents, and Edward Cope, of a well-known Philadelphia Quaker family, became one of the most eminent naturalists and paleontologists of the nineteenth century, and unaided discovered over a third of the three thousand extinct species of vertebrates recognized by men of science.
Of course the remains are incomplete, and rarely adequate for a close comparison. The range of fluctuating variability should be examined first, but the test of elementary species given by their constancy from seed cannot, of course, be applied. Apart from these difficulties, paleontologists agree in recognizing the very great age of large numbers of species.
We are brought one step nearer to the desired inference by the similar "fact, insisted on by all paleontologists, that fossils from two consecutive formations are far more closely related to each other than are the fossils of two remote formations.
It is desirable to speak of these excellent books, and of their distinguished authors, with the utmost respect, and in a tone as far as possible removed from carping criticism; indeed, if they are specially cited in this place, it is merely in justification of the assertion that the following propositions, which may be found implicitly, or explicitly, in the works in question, are regarded by the mass of paleontologists and geologists, not only on the Continent but in this country, as expressing some of the best-established results of paleontology.
If he did, he saw no escape from the dilemma, for it seemed to him that the record in the rocks clearly disproved the alternative Lamarckian hypothesis. And almost with one accord the paleontologists of the time sustained the verdict. Owen, Agassiz, Falconer, Barrande, Pictet, Forbes, repudiated the idea as unqualifiedly as their great predecessor Cuvier had done in the earlier generation.
They can only be likened to the monsters of the early dawn on the earth, in the age of the dinosaurs. But they are sui generis, and would make our anatomists and paleontologists stare. I am only surprised that we have encountered no flying dragons here." "But was it really a a giant spider that captured Ala's man?" I asked with a shudder. "God knows what it was!
