Mammal-like reptile 
 Mammal-like reptile is an old term for the therapsids: those synapsids which gave rise to the true mammals.
Mammal-like reptile 
 Both groups descended from early amniotes (egg-laying tetrapods), probably in the Lower or Middle Carboniferous.
Mammal-like reptile 
 The precursors of reptiles are called sauropsids, and the precursors of mammals are called synapsids.
Mammal-like reptile 
 There are a number of characteristics which cannot be seen on fossils, but which are of great importance.
Mammal-like reptile 
 Mammals are distinguished from reptiles by fundamental differences in the development of the blood system.
Mammal-like reptile 
 These differences are such that it would be almost impossible for mammals to be derived from reptiles.
Mammal-like reptile 
 " It is clearly quite impossible for the condition found in birds and modern reptiles to have arisen from that found in mammals or vice versa".
Cleidoic egg 
 The shell is porous to air, and may be flexible or calcareous (hard).The calcareous shell prevents the egg from desiccation.
Cleidoic egg 
 The special membranes that support these eggs are typical traits of all amniotes, including mammals.
Cleidoic egg 
 The significance of the cleidoic egg is that it enables reproduction out of, and often away from, water.
Cleidoic egg 
 The cleidoic egg has been called "a private little pond", from the way it gives water and nutrition to the embryo.
Cleidoic egg 
 Cleidoic eggs must have evolved in the early or middle Carboniferous, after the early tetrapods evolved, but before the amniotes split into sauropsids (reptile ancestors) and synapsids (mammal ancestors).
Cleidoic egg 
 The basic reproduction strategy of amphibia (frogs, for example), is to lay a huge number of eggs, which are left to their own fate.
Cleidoic egg 
 The strategy of amniotes is to invest more in the production of eggs, lay fewer eggs and take some care of them.
Cleidoic egg 
 All mammals provide milk for their young, and many smaller mammals raise their young in burrows, providing a meaasure of security.
Cleidoic egg 
 Actually,the embryo developing in the womb has the same membranes round it as does the embryo inside a bird egg.
Cleidoic egg 
 Live birth has evolved independently a number of times in reptiles, for example Ichthyosaurs gave birth to live young.
Cleidoic egg 
 The cleidoic egg is a good example of an evolutionary innovation which permitted the invasion of a vast range of new habitats, and led to one of the greatest adaptive radiations in the history of the vertebrates.
Cleidoic egg 
 In comparison, the amphibia, whose reproduction is tied to water, are represented today by just a few highly specialised groups.
Cleidoic egg 
 Some authors make a distinction between amniotic eggs (of reptiles, birds and mammals) and closed eggs of invertebrate groups such as insects and spiders.
Terrapin 
 The name "terrapin" is derived from torope, a word in the Native American Algonquian language that refers to the species, Malaclemys terrapin.
Terrapin 
 It appears that it became part of common usage during the colonial era of North America and was carried back to Great Britain.
Regions of Brazil 
 Brazil is currently divided into five regions (also called macroregions) by the Instituto Brasileiro de Geografia e Estatística (IBGE).
Regions of Brazil 
 These divisions are composed of states with similar cultural, economical, historical and social aspects, and, although information given by this type of division is not very accurate from the scientific point of view, this division is the most widely used in Brazil because official information given by the IBGE uses this system.

Mantle (mollusc) 
 The mantle is a significant part of the anatomy of molluscs: it is the dorsal body wall which covers the organs of digestion, reproduction and movement.
Mantle (mollusc) 
 In many, but not all, species of molluscs, the epidermis (skin) of the mantle secretes calcium carbonate and conchiolin, and creates a shell.
Mantle (mollusc) 
 The edges of the mantle may extend far beyond the main part of the body, forming flaps, double-layered structures adapted for many different uses, including for example, the siphon.
Mantle (mollusc) 
 This space contains the mollusc's gills, anus, and organs for taste, excretion and reproductive organs.
Mantle (mollusc) 
 In some mollusks the mantle cavity is a brood chamber, and in cephalopods and some bivalves such as scallops, it is a locomotory organ.
Mantle (mollusc) 
 In cephalopods the contraction of the mantle is used to force water through a tubular siphon, and this propels the animal rapidly through the water.
Carboniferous 
 In the U.S.A. the Carboniferous is divided into the Mississippian (lower part, 359–323.2 mya) and the Pennsylvanian (upper part, 323.2–299 mya).
Carboniferous 
 The early tetrapods split first into two major groups: the amphibians, which laid their eggs in water, and the amniotes, who laid their cleidoic eggs on land.
Carboniferous 
 They were the synapsids, which eventually gave rise to the mammals, and the sauropsids, which gave rise to the dinosaurs and other reptiles.
Carboniferous 
 The Carboniferous is named after the coal measures, the remains of peat formed by dense tropical wetland forests.
Carboniferous 
 This biota occurred in the upper part of the period, the Pennsylvanian, from 315 to 300 million years years ago.
Carboniferous 
 These forests were on the equator, and the wetlands, which are always low-lying, stretched across the supercontinent of Laurussia.
Carboniferous 
 This included what is now North America in the west, through what is now Europe to China in the east.
Carboniferous 
 The river plain which was the heart of the wetland stretched 5000 km from eastern Canada to Ukraine, and was 700 km wide.p6
Carboniferous 
 In the Carboniferous, the great tropical rainforests of Euramerica supported towering lycopodiophyta, and a mix of vegetation, as well as a great diversity of animal life: giant dragonflies, millipedes, cockroaches, amphibians, and the first amniotes.
Carboniferous 
 This kind of climate and geography has no exact parallel today, but the peat swamp forests in Indonesia and Malaysia, the Amazon Basin, the Mississippi River system and the Okefenokee swamp give some idea.
Carboniferous 
 Sometimes other plants from the levee got swept down by the river, such as horsetails, ferns and tree-like pteridosperms.
Carboniferous 
 The wetland forests ended when the land level was raised by the pressure of the Gondwana continent against Laurussia.
Mesozoic 
 It lasted about 186 million years, starting 252.2 mya (million years ago) with the P/Tr extinction and ending 66 mya with the K/T extinction (the one that killed all dinosaurs except birds).
Mesozoic 
 Although mammals seem to have originated in the Upper Triassic, their fate was quite different to the dinosaurs.
Mesozoic 
 Mammals spent most of the long Jurassic and Cretaceous periods as small nocturnal animals living mainly in forests.
Mesozoic 
 The ecology of this world was quite different to that of the Pleistocene, the era when humans evolved.
Mesozoic 
 For much of human history we lived in a cold world with quite a sharp difference between land and sea.
Mesozoic 
 There was little or no ice at the poles and the continents had large areas covered with shallow continental seas.
Mesozoic 
 Textbooks have always described how the Mesozoic was the age of the dinosaurs, which has even more sense now that we know birds descended from land dinosaurs.
Mesozoic 
 Mammals were mainly small nocturnal animals which scurried around in the night-times of the great forests.
Mesozoic 
 We know from their loss of colour vision (which is trichromatic in fish and reptiles) that they lived a nocturnal life.
Palaeozoic 
 It lasted from about 541 to 252 million years ago (mya), and ended with the greatest extinction event, the Permian–Triassic extinction event.
Palaeozoic 
 The era saw many important events, including the development of most invertebrate groups, life's conquest of land, the evolution of fish, reptiles, synapsids (the ancestors of mammals), amphibians, insects, and plants, the formation of the supercontinent of Pangea, and at least two distinct ice ages.
Palaeozoic 
 The earth rotated faster than it does today so days were shorter, and the nearer moon caused stronger tides.
Palaeozoic 
 The carbon dioxide level dropped throughout the Carboniferous, and the oxygen level rose continuously until it dropped in the Permian.
Blackjack 
 Blackjack (Twenty-one, pontoon or Vingt-et-un) is a kind of card game which usually involves gambling.
Blackjack 
 There is a dealer, who deals cards from a special device called a 'dealer's shoe' or a 'shuffling machine'.
Blackjack 
 This is because they are the common cause of 'busting' the dealer hand and because they are needed for a blackjack.
Blackjack 
 Over the years the origin of Blackjack, like many other games, has eluded researchers for a long time and which continues to be hotly debated to this day.
Blackjack 
 Till date there has been no clear consensus, but most agree it probably originated in French casinos around 1700, where it was called Vingt-et-Unwhich, translated, means twenty-one.
Blackjack 
 Most believe it was probably derived from the French card games, Chemin de Fer, and French Ferme, which were in vogue at that time.
Blackjack 
 Among the various versions of the game, 'Vingt-et-Un' or '21' continued to grow in popularity and reach.
Blackjack 
 It gradually spread to North America thanks to French colonists and soon after it was played throughout the continent.
Blackjack 
 The game was still termed '21' when it gained popularity in Nevada in 1931 as the State first chose to make gambling legal.
Blackjack 
 To draw more people to the game, some casinos then offered a special bet: A hand featuring either of the black jacks (the Jack of Spades or that of Clubs) plus the Ace of Spades would pay 10-to-1 odds on the lucky player's bet.
Blackjack 
 Although casinos later discontinued this peculiar payout, the name 'blackjack' or 'black jack' remained, as the game is known today.
Blackjack 
 The name has nothing to do with Sherlock Holmes but refers to a famous gambler who is supposed to have won £10,000 at Faro through his wager in connection with this card.
Blackjack 
 On the contrary, blackjack has evolved over centuries; it continues to evolve and grow even today, thanks to the Internet.
Blackjack 
 Fuelling its popularity the online casino industry has developed various versions of the game which has truly revolutionized it.
Blackjack 
 Now a few reputed casino operators have started an innovative and far more enjoyable concept of this game: live blackjack game with real dealers.
Blackjack 
 Live Blackjack is the most advanced way to play your favourite casino game right in the comfort of your home, without having to go a long way to a field-based casino.
Blackjack 
 One of the dealer's two cards is face-up so all the players can see it (an Ace), and the other is face down.
Blackjack 
 Black gets an Ace and 2 which is worth either 13 or 3, and asks for a hit and gets a King (worth 10) which takes black to 13; black hits again, gets 16 and decides to stand.
Blackjack 
 Splitting a K and J may be possible in some games although it is unusual to split a 20 because it is such a high hand)
Blackjack 
 White gets two 5s, so they double the bet and split the cards, the dealer gives them a 5 and a 7 for each.
Blackjack 
 The dealer turns their card over and gets a 6, together with the Ace takes them to 17, and stands because the dealer must stand on 17. (
Blackjack 
 White's 21 is paid at 2:1, which means that white receives double and a half the amount of chips white bet for one of the splits, however white loses the other half of chips bet on the 16 which is beaten by the dealer's 17.
Blackjack 
 You can actually get to 21 in many different ways, but the ace and 10-point card combination will beat those variations.
Blackjack 
 With an open ace or a dozen (in some variations only with ace), the dealer looks at the hidden card and, if the blackjack dealer, the game ends.
Blackjack 
 In the case of a blackjack dealer, the players are returned all additional bets (except for "insurance"),
Blackjack 
 On the basis of Blackjack, numerous versions have been created, with their own names such as Blackjack in the open (Double Exposure), 3-Card Blackjack, Blackjack Switch, Spanish 21, Caribbean 21, Super Fan 21, Pontoon, etc.
Phanerozoic 
 It covers about 541 million years, and goes back to the time when hard-shelled animals first appeared.
Phanerozoic 
 The time before the Phanerozoic, formerly called the Precambrian, is now divided into the Hadean, Archaean and Proterozoic eons.
Phanerozoic 
 It might be where the first trilobites and archaeocyatha appear; or at the first appearance of signs of burrowing; or at the first appearance of the 'small shelly fauna'.
Phanerozoic 
 During the period covered, continents drifted about, eventually collecting into a single landmass known as Pangea and then splitting up into the current continental landmasses.
Ordovician 
 He recognized that the fossils in the disputed strata were different from those of the Cambrian or the Silurian.
Ordovician 
 In 1906 it was adopted as an official period of the Paleozoic era by the International Geological Congress.
Ordovician 
 The Ordovician ended with a series of extinction events that, together amount to the second greatest extinction of the Phanerozoic.
Ordovician 
 Gondwana started the period in equatorial latitudes and, as the period progressed, drifted toward the South Pole.
Ordovician 
 Early in the Ordovician, the continents Laurentia (present-day North America), Siberia, and Baltica (present-day northern Europe) were still independent continents.
Ordovician 
 The Ordovician was a time of calcite sea geochemistry in which low-magnesium calcite was the main marine precipitate of calcium carbonate.
Ordovician 
 For most of the Ordovician, life continued to flourish, but near the end of the period the EndOrdovician extinction event seriously affected planktonic forms like conodonts, graptolites, and some groups of trilobites.
Ordovician 
 Brachiopods, bryozoans and echinoderms were also heavily affected, and the cone-shaped nautiloids died out completely, except for rare Silurian forms.
Ordovician 
 The extinctions may have been caused by an ice age that occurred at the end of the Ordovician period: the end of the Ordovician was one of the coldest times in the last 600 million years of earth history.
Ordovician 
 On the whole, the fauna that emerged in the Ordovician set the scene for the rest of the Palaeozoic.
Ordovician 
 Though less famous than the Cambrian explosion, the Ordovician featured an adaptive radiation, which was no less remarkable.
Ordovician 
 This illustrates the greatly increased biodiversity of carbonate shell-secreting organisms in the Ordovician compared to the Cambrian.
Ordovician 
 Although solitary corals date back to at least the Cambrian, reef-forming corals appeared in the early Ordovician.
Ordovician 
 Molluscs, which appeared during the Cambrian or even the Ediacaran, became common and varied, especially bivalves, gastropods, and nautiloid cephalopods.
Ordovician 
 It was long thought that the first true vertebrates (fish — Ostracoderms) appeared in the Ordovician, but recent discoveries in China show they probably originated in the Lower Cambrian.
Ordovician 
 During the Middle Ordovician there was a large increase in bioeroding (shell and rock-boring) organisms.
Ordovician 
 In the Lower Ordovician, trilobites were joined by many new brachiopods, bryozoans, planktonic graptolites and conodonts, and many types of molluscs and echinoderms, including the ophiuroids ("brittle stars") and the first sea stars.
Ordovician 
 Nevertheless the trilobites remained abundant, with all the Late Cambrian orders continuing, and being joined by the new group Phacopida.
Ordovician 
 Many trilobites developed bizarre spines and nodules to defend against predators such as primitive sharks and nautiloids.
Ordovician 
 Some trilobites such as Asaphus kowalewski evolved long eyestalks to assist in detecting predators whereas other trilobite eyes in contrast disappeared completely.
Ordovician 
 It is now known that it did not go extinct, but survived, and thrived where the circumstances were right.
Ordovician 
 A recently discovered lagerstätte (a deposit of exceptionally preserved fossils) has been found in the Fezouata Formation, Morocco.
