Some Oligocene Mammals - Neolithic Implements
Finally, perhaps as early as 3000 years ago in Europe, and even{v1-107} earlier in Asia Minor, men began to smelt iron. Once smelting was known to men, there is no great marvel in the finding of iron. They smelted iron by blowing up a charcoal fire, and wrought it by heating and hammering. They produced it at first in comparatively small pieces; its appearance worked a gradual revolution{v1-108} in weapons and implements; but it did not suffice to change the general character of men’s surroundings. Much the same daily life that was being led by the more settled Neolithic men 10,000 years ago was being led by peasants in out-of-the-way places all over Europe at the beginning of the eighteenth century. People talk of the Stone Age, the Bronze Age, and the Iron Age in Europe, but it is misleading to put these ages as if they were of equal importance in history. Much truer is it to say that there was: (1) An Early Palæolithic Age, of vast duration; (2) a Later Palæolithic Age, that lasted not a tithe of the time; and (3) the Age of Cultivation, the age of the white men in Europe, which began 10,000 or at most 12,000 years ago, of which the Neolithic Period was the beginning, and which is still going on. - The Horned Ceratosaurus, a Carnivorous Dinosaur

Head of the early ancestor of elephants—Meritherium—as it appeared in life. Observe the absence of a trunk and the enlarged front tooth in the upper jaw, which is converted in later members of the elephant-stock or line of descent into the great tusk. (After a drawing by Prof. Osborne.) - Early Pleistocene Animals, Contemporary with Earliest Man
Geologists make certain main divisions of the Cainozoic period, and it will be convenient to name them here and to indicate their climate. First comes the Eocene (dawn of recent life), an age of exceptional warmth in the world’s history, subdivided into an older and newer Eocene; then the Oligocene (but little of recent life), in which the climate was still equable. The Miocene (with living species still in a minority) was the great age of mountain building, and the general temperature was falling. In the Pliocene (more living than extinct species), climate was very much at its present phase; but with the Pleistocene (a great majority of living species) there set in a long period of extreme conditions—it was the Great Ice Age. - Koch's Hydrarchus. Composed of Portions of the Skeletons of Several Zeuglodons
One might think that a creature sixty or seventy feet long was amply long enough, but Dr. Albert Koch thought otherwise, and did with Zeuglodon as, later on, he did with the Mastodon, combining the vertebræ of several individuals until he had a monster 114 feet long! This he exhibited in Europe under the name of Hydrarchus, or water king, finally disposing of the composite creature to the Museum of Dresden, where it was promptly reduced to its proper dimensions. The natural make-up of Zeuglodon is sufficiently composite without any aid from man, for the head and paddles are not unlike those of a seal, the ribs are like those of a manatee, and the shoulder blades are precisely like those of a whale, while the vertebræ are different from those of any other animal, even its own cousin and lesser contemporary Dorudon - Head of the ancestral elephant
Head of the ancestral elephant—Palæomastodon—as it appeared in life. It shows, as compared with the earlier ancestor, an elongation both of the snout and the lower jaws. The tusk in the upper jaw has increased in size, but is still small as compared with that of later elephants. (After a drawing by Prof. Osborne.) - Cro-magnon Man
In the grotto of Cro-Magnon it was that complete skeletons of one main type of these Newer Palæolithic men, these true men, were first found, and so it is that they are spoken of as Cro-Magnards. - Skeleton of Triceratops

Drawing of the skull and lower jaw of the Meritherium, discovered by Dr. Andrews in the Upper Eocene of the Fayum Desert. The shape of the skull and proportions of face and jaw are like those of an ordinary hoofed mammal such as the pig; but the cheek-teeth are similar to those of the Mastodon, and whilst the full complement of teeth is present in the front of the upper jaw, we can distinguish the big tusk-like incisor which alone survives on each side in Palæomastodon, Mastodon, and the elephants, as the great pair of tusks. - Hesperornis, the Great Toothed Diver

- Skeleton of a Radiolarian Very Greatly Enlarged
The very rocks themselves may consist largely of fossils; chalk, for example, is mainly made up of the disintegrated shells of simple marine animals called foraminifers, and the beautiful flint-like "skeletons" of other small creatures termed radiolarians, minute as they are, have contributed extensively to the formation of some strata. - Triceratops - A Huge Extinct Reptile
(From remains found in Cretaceous strata of Wyoming, U.S.A.) This Dinosaur, about the size of a large rhinoceros, had a huge three-horned skull with a remarkable bony collar over the neck. But, as in many other cases, its brain was so small that it could have passed down the spinal canal in which the spinal cord lies. Perhaps this partly accounts for the extinction of giant reptiles. - Pottery from Lake Dwellings
The milk, if they did use it (and, no doubt, in that case sour curdled milk also, but not well-made cheese and butter), they must have kept in earthenware pots, for they had pottery, though it was roughly hand-made pottery and not the shapely product of the potter’s wheel. - A Great Sea Lizard Tylosaurus Dyspelo
The finest Mosasaur skeleton ever discovered, an almost complete skeleton of Tylosaurus dyspelor, 29 feet in length, may be seen at the head of the staircase leading to the Hall of Paleontology, in the American Museum of Natural History, New York. Another good specimen may be seen in the Yale University Museum, which probably has the largest collection of Mosasaurs in existence. - Reindeer Age Engravings and Carvings

In the light of our present knowledge we are able to read many things in these tracks that were formerly more or less obscure, and to see in them a complete verification of Dr. Deane's suspicion that they were not made by birds. We see clearly that the long tracks called Anomœpus, with their accompanying short fore feet, mark where some Dinosaur squatted down to rest or progressed slowly on all-fours, as does the kangaroo when feeding quietly;[3] and we interpret the curious heart-shaped depression sometimes seen back of the feet, not as the mark of a stubby tail, but as made by the ends of the slender pubes, bones that help form the hip-joints. Then, too, the mark of the inner, or short first, toe, is often very evident, although it was a long time before the bones of this toe were actually found, and many of the Dinosaurs now known to have four toes were supposed to have but three. - A Tooth of Zeuglodon, One of the 'Yoke Teeth,' from which it derives the name

Early Stone Implements The Mousterian Age implements, and all above it, are those of Neanderthal men or, possibly in the case of the rostro-carinates, of sub-men. The lower row (Reindeer Age) are the work of true men. The student should compare this diagram with the time diagram attached to Chapter VII, § 6, and he should note the relatively large size of the pre-human implements. - Hind Feet of Dinosaurs

Take, for instance, the art of making bread, which was probably practised by the earlier races in some such manner as that represented in the figure. , wherein is depicted the process employed by certain savage tribes at the present day. Rude as the process is—and it consist only in spreading the paste, made of flour and water, on a series of flat stones which have been heated in a fire—its employment betoken the knowledge of a certain number of the facts of nature. It required the experience of perhaps many ages to impart the knowledge of other fads by which the originally .rude process became improved. This progress of an art, from its rudest to its more advanced state, doe not necessarily imply an advance in science. - Outline Restorations of Dinosaurs
Outline Restorations of Dinosaurs - Phororhacos, a Patagonian Giant of the Miocene
Phororhacos, a Patagonian Giant of the Miocene From a Drawing by Charles R. Knight Most recent in point of discovery, but oldest in point of time, are the giant birds from Patagonia, which are burdened with the name of Phororhacidæ, a name that originated in an error, although the error may well be excused. The first fragment of one of these great birds to come to light was a portion of the lower jaw, and this was so massive, so un-bird-like, [149]that the finder dubbed it Phororhacos, and so it must remain.
