	List of mammals - Wikipedia, the free encyclopedia
		The class Mammalia (the Mammals) is divided into two subclasses based on reproductive techniques: egg laying mammals (the Monotremes); and mammals which give live birth.
		The latter subclass is divided into two infraclasses: pouched mammals (the marsupials); and the placental mammals.
		This list is incomplete; you can help by expanding it.

	What is a Mammal
		No other animal has hair in the same form as mammals, and all mammals have some hair at least at the beginning of their lives - baby whales and dolphins are born with a moustache.
		Mammals, or Mammalia are a class in the Phylum Chordata and the Subphylum Vertebrata.
		Mammals are heterodontic, meaning that their teeth are different shapes, except those with no teeth at all.

	Some notes on the history and diversity of placental mammals
		Placental mammals provide something like 94% of all existing mammalian species; rats to whales and shrews to you.
		Both placentals and marsupials are descendants of the first therian; a common ancestor not shared by the monotremes.
		Mammals are all derived from a small, four-legged generalist who preyed on insects and grubs; an animal such as Morganucodon.

	Paleocene mammals of the world
		Throughout the Mesozoic, most mammals were small, fed on insects and lead a nocturnal life, whereas dinosaurs were the dominant forms of life on land.
		By this time, the landscape was teeming with small insectivorous and rodent-like mammals, medium sized mammals were searching the forests for any kind of food they could cope with, the first large (but not yet gigantic) mammals were browsing on the abundant vegetation, and carnivorous mammals were stalking their prey.
		Unfortunately, mammal fossils from this epoch are either scarce or entirely unknown in many parts of the world.

		One of the features of all mammals is the presence of interlocking teeth which results in improved chewing (the upper and lower teeth in the jaw work together to cut or crush and grind food).
		Both marsupials and placentals give birth to live young, but the marsupials have very immature newborns that they usually place in a pouch, while the placentals carry their young in their bodies until a later stage of growth and give birth to relatively more mature newborns.
		Placental mammals all bear live young, which are nourished before birth in the mother's uterus through a specialized embryonic organ attached to the uterus wall, the placenta.

	Mammals
		Mammals have large brain sizes compared to their bodies, and they have strong teeth.
		When mammal young are born, the mother continues to protect them, feeding them milk from her body.
		The young of placentals stay in the uterus until they are ready to be born.

	The Malay Archipelago, Volume II - Chapter XXVII. The Natural History of the Moluccas (Alfred R. Wallace)
		The land mammals are exceedingly few in number, only ten being yet known from the entire group.
		But even this exceeding poverty of terrestrial mammals does not at all represent the real poverty of the Moluccas in this class of animals; for, as we shall soon see, there is good reason to believe that several of the species have been introduced by man, either purposely or by accident.
		The four remaining mammals are Marsupials, an order of the class Mammalia, which is very characteristic of the Australian fauna; and these are probably true natives of the Moluccas, since they are either of peculiar species, or if found elsewhere are natives only of New Guinea or North Australia.

	Mammalia
		Although the first mammals date from the early part of the Mesozoic Era, mammals flourished and radiated only after the extinction the dinosaurs and other groups of reptiles that dominated the land, sea, and air during the Mesozoic era.
		Mammals are distinguished by the presence of 1) hair, and 2) mammary glands, and 3) three middle ear bones.
		Indeed, marsupial species show a parallel series of adaptations to the environment that is seen in placental mammals in other parts of the world.

	Transitional Vertebrate Fossils FAQ: Part 1B
		All early mammals from the Lower Jurassic have this low-frequency ear and a double jaw joint.
		By the middle Jurassic, mammals lost the reptilian joint (though it still occurs briefly in embryos) and the two bones moved into the nearby middle ear, became smaller, and became much more sensitive to high-frequency sounds.
		Placentals appear to have arisen in East Asia and spread to the Americas by the end of the Cretaceous.

	SHREWS & MOLES
		Insectivores are the descendants of the most primitive placental mammals and are the predecessors of all other placental mammals.
		Among the primitive features that many insectivores exhibit are the structure of the ears, the small brain, primitive teeth, testes that are usually inside the abdomen rather than in a scrotum, and the joining of the urinary and reproductive tracts and the intestine into a common channel called a cloaca.
		With the highest surface area relative to body mass of all mammals, much of the heat they generate metabolically to maintain their body temperature soon dissipates into the air.

	Non-reptilian life in Mesozoic Australia
		The mammal material from the Strzelecki Group of sites is much better preserved, and dates to about 115 million years ago.
		The form of the mandible and the number and shape of the teeth suggest that Ausktribosphenids are primitive placental mammals, perhaps related to the Erinaceidae, the family that includes hedgehogs.
		When Ausktribosphenos was first described, and argued to be a placental mammal, a theory was put forward to explain how placentals came to appear in the Late Cretaceous in other parts of the world, separated from the Gondwanan countries by ocean barriers in most cases.

	Science & Technology at Scientific American.com: Shaking the Family Tree -- A new fossil leaves former theories out ... (Site not responding. Last check: 2007-10-21)
		This possibly placental creature, named Ausktribosphenos nyktos, apparently scurried out of the way of dinosaurs in what is now Australia during the Cretaceous--some 110 million years before the accepted appearance of such mammals there.
		The trouble is that the fossil was wrested from Cretaceous rock that was 115 million years old while well-established theory holds that the first placental mammals in Australia were island-hopping rodents that arrived a mere 5 million years ago.
		The researchers' conclusion that terrestrial placental mammals may have lived down under 110 million years earlier than expected, as reported in the November 21, 1997 issue of Science, could all but uproot the mammalian family tree.

		Mammals are denoted mainly by soft anatomy characteristics (hair and mammary glands) and the tiny ear ossicles, the malleus and incus, that are usually lost in fossils.
		The main characteristics that suggest their primitiveness are eggs (they lay them), the lack of a nipple (they secrete milk from patches of skin without a discreet nipple), and the more splayed appearance of their legs.
		Placentals are unique in the preciousness of their offspring compared to most other vertebrates.

		For example, the mammals currently living on the island continent of Australia combine a unique ancestry of monotremes and marsupials that have evolved into ecological niches similar to placentals in the northern hemisphere.
		the mammals shown in North America, including the gigantic ground sloths, armadillos, and glyptodonts were immigrants from the south, whereas the mammals shown in South America, including mastodons, tapirs, llamas, and horses were immigrants from the north.
		Ever since the turn of the century, fabulous fossil mammals have been collected from this region and they form the basis for our understanding of the extinct mammals that evolved in isolation on what was then a floating, isolated, island continent.

	- Camp answers Theobald -
		Many hundreds of phylogenies of mammals have been published, some based on morphological data and others based on molecular data (proteins, nucleic acids), and yet there is no evidence that these hypotheses of relationship are converging on a single viewpoint.
		To preempt being accused of thinking that the discovery of a birdlike mammal would necessarily force a shift in thinking about the relationship of mammals and birds (a placing of their branches next to each other), I acknowledged the possibility that the birdlike features could be attributed to convergent evolution.
		The suggestion that universal common ancestry would be falsified by “the discovery of a mammal without crossed gastrointestinal and respiratory tracts, or a reptile or mammal without blindspots in its eyes” is incorrect.
