- molars of elephants
The crowns of three "grinders" or molars of elephants compared. a is that of an extinct mastodon with four transverse ridges; b is that of the African elephant with nine ridges in use and ground flat; c is that of the mammoth with sixteen narrow ridges in use—the rest, some eight in number, are at the left hand of the figure and not yet in use. - Miocene Mammals
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. - Mammoth

- Life in the Later Palæozoic Age
Life is creeping out of the water. An insect like a dragon fly is shown. There were amphibia like gigantic newts and salamanders, and even primitive reptiles in these swamps. - Life in the Early Palæozoic
Note its general resemblance, except for size, to the microscopic summer ditch-water life of to-day. - Leg of a Horse Compared with that of the Giant Moa
- 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 - Hut Urns

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.) - 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.) - Hafting

- Great Extinct Bul
Skull of the great extinct Bull, the Bos primigenius, or the Urus, or Aurochs. The measurement from one horn tip to the other taken round the curves, was in some cases eight feet. The Urus stood in rare instances as much as seven feet at the shoulder; a fair-sized elephant stands nine feet. - Grazing Reindeer, engraved on a round bone
