- Where a Dinosaur Sat Down
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. - 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. - Tooth of Mastodon and of Mammoth

- The walking-fish or mud-skipper (Periophthalmus)
It skips about by means of its strong pectoral fins on the mud-flats; it jumps from stone to stone hunting small shore-animals; it climbs up the roots of the mangrove-trees. The close-set eyes protrude greatly and are very mobile. The tail seems to help in respiration. - The Track of a Three-toed Dinosaur

(After William Leche of Stockholm.) A good restoration of the oldest known bird, Archæopteryx (Jurassic Era). It was about the size of a crow; it had teeth on both jaws; it had claws on the thumb and two fingers; and it had a long lizard-like tail. But it had feathers, proving itself a true bird. - Some Reptiles of the Late Paleozoic Age

- Skeleton of Tyrannosaurus in comparison with human skeleton
This animal probably reached the maximum of size and of development of teeth and claws of which its type of animal mechanism was capable. Its bulk precluded quickness and agility. It must have been designed to attack and prey upon the ponderous and slow moving Horned and Armored Dinosaurs with which its remains are found, and whose massive cuirass and weapons of defense are well matched with its teeth and claws. The momentum of its huge body involved a seemingly slow and lumbering action, an inertia of its movements, difficult to start and difficult to shift or to stop. - Skeleton of Triceratops

- Skeleton of an Extinct Flightless Toothed Bird, Hesperornis
The bird was five or six feet high, something like a swimming ostrich, with a very powerful leg but only a vestige of a wing. There were sharp teeth in a groove. The modern divers come nearest to this ancient type. - 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. - Restoration of a Lake Dwelling
One fruitful source of knowledge about Neolithic life comes from Switzerland, and was first revealed by the very dry winter of 1854, when the water level of one of the lakes, sinking to an unheard-of lowness, revealed the foundations of prehistoric pile dwellings of the Neolithic and early Bronze Ages, built out over the water after the fashion of similar homes that exist to-day in Celebes and elsewhere. Not only were the timbers of those ancient platforms preserved, but a great multitude of wooden, bone, stone, and earthenware utensils and ornaments, remains of food and the like, were found in the peaty accumulations below them. Even pieces of net and garments have been recovered. Similar lake dwellings existed in Scotland, Ireland, and elsewhere—there are well-known remains at Glastonbury in Somersetshire; in Ireland lake dwellings were inhabited from prehistoric times up to the days when O’Neil of Tyrone was fighting against the English before the plantation of Scotch colonists to replace the Irish in Ulster in the reign of James I of England. These lake villages had considerable defensive value, and there was a sanitary advantage in living over flowing water. - Reindeer Age Engravings and Carvings

- Pterichthys, the Wing Fish
erichthys, the wing fish, was another small, quaint, armor-clad creature, whose fossilized remains were taken for those of a crab, and once described as belonging to a beetle. Certainly the buckler of this fish, which is the part most often preserved, with its jointed, bony arms, looks to the untrained eye far more like some strange crustacean than a fish, and even naturalists have pictured the animal as crawling over the bare sands by means of those same arms. These fishes and their allies were once the dominant type of life, and must have abounded in favored localities, for in places are great deposits of their protective shields jumbled together in a confused mass, and, save that they have hardened into stone, lying just as they were washed up on the ancient beach ages ago. How abundant they were may be gathered from the fact that it is believed their bodies helped consolidate portions of the strata of the English Old Red Sandstone. - Primitive Sledge

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. - Prehistoric Whistle
A musical relic has recently been exhumed in the department of Dordogne in France, which was constructed in an age when the fauna of France included the reindeer, the rhinoceros, and the mammoth, the hyæna, the bear, and the cave-lion. It is a small bone somewhat less than two inches in length, in which is a hole, evidently bored by means of one of the little flint knives which men used before acquaintance with the employment of metal for tools and weapons. Many of these flints were found in the same place with the bones. Only about half a dozen of the bones, of which a considerable number have been exhumed, possess the artificial hole. - 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. - Pithecanthropos Erectus
The first race of Man (circa 550,000 B.c.) is called the "Pithecanthropos Erectus," or Ape Man. They were powerfully built individuals, with low foreheads, prominent bony ridges above the eyes, and retreating chins. Their forearms were heavy and clumsy, their thigh-bones bent and their shin-bones short, so they must have been bow-legged and awkward in gait. This type of human being became differentiated from animals because development of the faculty of primitive speech enabled them to sustain thought and created memory. - 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. - Pariasaurus - An Extinct Vegetarian Triassic Reptile

Outline Restorations of Dinosaurs - Neolithic or New Stone Age Man
The Neolithic or New Stone Age: Circa 10,000 B.C. The people of this period constituted a fifth race of mankind, of moderate stature and slender proportions. Those who resided on the western side of the island now known as Great Britain were dark, and of the Iberian type. Those on the eastern side were fair, and very like the Gauls. - 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. - Neanderthal Man
They probably used a multitude and variety of wooden implements also; they had probably learnt much about the shapes of objects and the use of different shapes from wood, knowledge which they afterwards applied to stone; but none of this wooden material has survived; we can only speculate about its forms and uses. As the weather hardened to its maximum of severity, the Neanderthal men, already it would seem acquainted with the use of fire, began to seek shelter under rock ledges and in caves—and so leave remains behind them. Hitherto they had been accustomed to squat in the open about the fire, and near their water supply. But they were sufficiently intelligent to adapt themselves to the new and harder conditions. - Nautilus
A section through the Pearly Nautilus, Nautilus pompilius, common from Malay to Fiji. The shell is often about 9 inches long. The animal lives in the last chamber only, but a tube (S) runs through the empty chambers, perforating the partitions (SE). The bulk of the animal is marked VM; the eye is shown at E; a hood is marked H; round the mouth there are numerous lobes (L) bearing protrusible tentacles, some of which are shown. When the animal is swimming near the surface the tentacles radiate out in all directions, and it has been described as "a shell with something like a cauliflower sticking out of it." The Pearly Nautilus is a good example of a conservative type, for it began in the Triassic Era. But the family of Nautiloids to which it belongs illustrates very vividly what is meant by a dwindling race. The Nautiloids began in the Cambrian, reached their golden age in the Silurian, and began to decline markedly in the Carboniferous. There are 2,500 extinct or fossil species of Nautiloids, and only 4 living to-day. - Nature's Four Methods of Making a Wing - Bat, Pteryodactyl, Archæopteryx, and Modern Bird

The Miocene (with living species still in a minority) was the great age of mountain building, and the general temperature was falling. - Map of Europe 50,000 Years Ago
Possible Map of Europe 50,000 Years Ago - Mammoth Hunt
To pierce the skin of one of the large animals, such as a mastodon or mammoth, the hunters had to be close to the powerful beast. They hurled or jabbed their spears at the animal, and tried to confuse and immobilize their prey. Perhaps several hunters surrounded an isolated animal waving their arms and distracting it while one or two others speared it. If the animal was wounded, the hunters would have tracked it until it became very weak or went to water to drink. Even a mastodon, wounded and exhausted, or mired in the mud of a shallow lake, would have been relatively easy game for a small group of experienced hunters.
