44. Mammals A brief discussion of mammals, focusing on how they are evolutionarily advanced over other animal types http://www.backyardnature.net/mammals.htm

MAMMALS IN GENERAL R eptiles arose from amphibians, and birds arose from reptiles. However, mammals, such as the Armadillo shown above in my backyard, did not arise from birds. Mammals, like birds, arose from early reptiles, though from a different reptilian stock than the birds. Here are the main "new inventions" nature came up with that made us mammals more complex beings than amphibians, reptiles and birds: Mammals, like birds, but unlike their reptilian ancestors, are warm-blooded their bodies stay warm, even when surrounded by cold air. Mammal bodies are covered with hair, which helps the body stay warm; even the Armadillo above has hairs. Mammal teeth come in a variety of shapes, known as incisors, canines, premolars and/or molars, with each tooth type specialized for stabbing, cutting, tearing, or grinding of food. Reptilian teeth aren't nearly as diverse. Mammal ears are relatively complex, the middle ear containing three bones, as opposed to only one bone in the middle ear of reptiles and birds. Mammal brains are much larger than those of reptiles, enabling greater intelligence and consequent flexibility of behavior.

The black-tailed prairie dog is the most abundant and widely distributed prairie dog. Black-tailed prairie dogs are a yellowish tan on the back and lighter on the belly. They have a short tail that is tipped with black. Their ears are short and an average adult weighs about two pounds. Prairie dogs are active only during daylight hours and spend a lot of time feeding and socializing. Colonies or "towns" are established in areas that have been heavily grazed by cattle. Since they do not like tall grass, they will choose a site which has little vegetation. Here, the prairie dog feels secure and able to see predators coming from a long distance. Burrows are usually quite visible because of the large mound of dirt around the entrance. Mounds provide both a vantage point and protection from flooding. Forbs are preferred over grasses for food so competition with cattle is still questionable. Prairie dogs will, however, clip off many grass species for better visibility, adding to the denuded look of a town.

These animals have long since gone extinct and are known mostly from fossils, from frozen, mummified carcasses, and even from ancient cave drawings. The Last Ice Age The last Ice Age started about 70,000 years ago and ended about 10,000 years ago (during the Pleistocene epoch). The Earth was much colder than it is now; snow accumulated on much of the land, glaciers and ice sheets extended over large areas and the sea levels were lower. These phenomena changed the surface of the earth, forming lakes, changing the paths of rivers, eroding land, and depositing sand, gravel, and rocks along the glaciers' paths.

Close Please copy/paste the following text to properly cite this HowStuffWorks article: Mammals, the group of vertebrates (animals with backbones) to which human beings belong. Mammals are distinguished from all other animals by their mammary glands, glands that produce milk to feed the young. Mammals are also unique in having hair, although it may be scant. They are warm-blooded and air-breathing, and all but the whales and sirenians, or sea cows, have four limbs. The Cenozoic Era, from sixty-five million years ago to the present, is the Age of Mammals. Mammals range in size from shrews that weigh 1/14 ounce (2 g) to whales that weigh 140 tons (127,000 kg). They are found in almost all parts of the world—in the tropics and the Arctic, in rain forests and deserts. Most kinds of mammals live on land. Some kinds, including whales and walruses, live in the water. Bats are the only flying mammals. All mammals except the duckbill platypus and the echidna, which lay eggs, give birth to live young. Mammals care for their young for longer periods than other animals do. Mammals have a more highly developed brain than other animals, with correspondingly higher intelligence.

55. Paleocene Mammals Of The World Information on this group of relatively unspecialized placental mammals that were to evolve into the ungulates that dominated the Cenozoic animal communities on land. http://www.paleocene-mammals.de/condylarths.htm

Condylarths: Archaic hoofed mammals Pantodonta The majority of condylarths is known from North America, the continent that has the most complete record of Paleocene mammals. Only few Paleocene mammal faunas have been discovered in Europe, but these show that condylarths were equally important in this part of the world and were often represented there by close relatives of North American forms. Surprisingly, only a few questionable condylarths have been described from the much richer Paleocene faunas of Asia. The ecological role of plant-eating mammals was taken over there by groups like the Anagalida and the Pantodonta. Yet these were hunted by carnivorous descendants of the condylarths, members of the order Mesonychia . South America is the only continent in the southern hemisphere that has a substantial record of Paleocene mammals, and the growing number of South American condylarths establishes an important link to the northern faunas. The most primitive known condylarth is the rat-sized Protungulatum ("before-ungulate") from the United States and Canada. Besides its occurrence in clearly early Paleocene sediments, remains of this genus are also found together with the teeth of dinosaurs. Therefore it was originally thought that

56. Mammals Dolphins. Like whales and porpoises, dolphins are mammals, not fish. mammals, unlike fish, feed their young with milk that is produced in the mother's body. http://library.thinkquest.org/J002113/mammals.htm

Home Fish Sharks Plant Life ... Credits Mammals Dolphins Whales Dolphins Like whales and porpoises, dolphins are mammals, not fish. Mammals, unlike fish, feed their young with milk that is produced in the mother's body. Also unlike fish, dolphins have lungs and are warm-blooded-that is, their body temperature always stays about the same, no matter what the temperature of their surroundings. Many scientists believe that dolphins rank among the most intelligent animals, along with chimpanzees and dogs. Dolphins, whales, and porpoises are members of a group of mammals called cetaceans. Dolphins and porpoises look a lot alike. Their chief differences occur in the mouth and teeth. Dolphins have a beak like mouth and cone-shaped teeth. Porpoises have a rounded snout and flat or spade-shaped teeth. Whales are way bigger than most dolphins and porpoises. Scientists apply the term dolphin to two families of cetaceans, marine dolphins and river dolphins. There are 32 species of marine dolphins. They are found in nearly all oceans, and most of them live only in salt water. Many species of marine dolphins remain near land for most of their lives, but some live in the open sea. River dolphins live in fresh or slightly salty water. The various species of dolphins usually range from 4 to 30 feet long and weigh from 100 pounds to 10 short tons (9 metric tons). The most familiar types are the bottle-nosed dolphin and the common dolphin. The bottle-nosed dolphin is the most widely known species. Its short beak gives this dolphin an expression that looks like a smile. Most performing dolphins in aquariums and zoos are bottle-nosed dolphins. Members of this species measure up to 13 feet long and can weigh as much as 600 pounds . They are gray, but their backs are darker than their undersides.

Skiftende utstillinger Mesozoic mammals Early Mammals The mammals first appeared at the same time as the dinosaurs, in the late Triassic, about 230 million years ago. Their ancestors were the mammal-like reptiles. During the first two thirds of mammalian history, when the dinosaurs ruled the Earth, the mammals were small, nocturnal animals about the size of mice and rats. When the dinosaurs died out 65 million years ago, the mammals were well equipped to exploit the different ecological niches left vacant, and their rapid evolution started. Triconodonts The triconodonts were the most primitive mammals. They looked like mammal-like reptiles - cynodonts - but were smaller. Like the cynodonts, they had molars with three cusps in a straight row. Large canines show that the triconodonts were carnivorous, but some may have been insectivores. They died out in the late Cretaceous. Multituberculates The multituberculates are an extinct side branch of the mammalian line; the first omnivorous mammals. They had large incisors, looking somewhat like modern rodents, and long multi-cusped molars. They were numerous and diverse in the late Cretaceous and the early Tertiary. They died out in the Oligocene, about 35 million years ago, probably because of competition from the rodents.

59. Paleocene Mammals Of The World Provides information on this diverse lineage of Mesozoic to early Cenozoic mammals with details of its biology and anatomy and an illustration of the Paleocene multituberculate, Ptilodus. http://www.paleocene-mammals.de/multis.htm

Multituberculates: Heyday of the longest lived mammalian order The order Multituberculata, informally also known as 'multis', is a diverse lineage of Mesozoic to early Cenozoic mammals that occupied a rodent-like niche. They appear first in the late Jurassic and are last known from the early Oligocene. The late Triassic haramiyids were sometimes considered as early multituberculates. More complete fossils have recently shown that haramiyids are a very different group of early mammals. But even without haramiyids, multituberculates existed for a time span of about 100 million years, the undisputed record for an order of mammals. Multituberculates do not belong to any of the groups of mammals living today: the primitive egg-laying monotremes and the more advanced marsupials and placentals, both also known as therians. The relationships of the multituberculates to these groups are still debated. Multituberculates have been considered as either a group that branched off even before the monotremes, as close relatives of the monotremes or as sister group of the therian mammals. Anyway, multituberculates were clearly very mammal-like, both in details of the internal anatomy, like the structure of the middle ear with the three auditory ossicles, and in external appearance, like the recently demonstrated possession of hair (see below). The anatomy of the pelvis suggests that multituberculates did not lay eggs like monotremes but gave birth to very small, immature young like marsupials. In the late Cretaceous multituberculates were widespread and diverse in the northern hemisphere, making up more than half of the mammal species of typical faunas. Although some lineages became extinct during the faunal turnover at the end of the Cretaceous, multituberculates managed very successfully to cross the K/T boundary and reached their peak of diversity during the Paleocene. They were an important component of nearly all Paleocene faunas of Europe and North America, and of some late Paleocene faunas of Asia. Multituberculates also were most diverse in size during the Paleocene, ranging from the size of a very small mouse to that of a beaver.
