Plesiosaurus was not a dinosaur.. Dinosaurs were land animals: despite their success, dinosaurs did not conquer the oceans, and only a few dinosaurs (e.g., Spinosaurus) are thought to have had semi-aquatic lifestyles. 18. Their food source is blood, a dietary trait called hematophagy.Three extant bat species feed solely on blood: the common vampire bat (Desmodus rotundus), the hairy-legged vampire bat (Diphylla ecaudata), and the white-winged vampire bat (Diaemus youngi). A vertebrate has a back thats straight. Well, not all vertebrates have straight backs, but all have backbones, or vertebral columns, that help support their bodies. b. A vertebrate has a back thats straight. Well, not all vertebrates have straight backs, but all have backbones, or vertebral columns, that help support their bodies.

19. the wing of a flying insect 20. Breathing through lungs. Among the mammals, humans are most closely related to primates such as the orangutan.

Powered flight has evolved unambiguously only four timesbirds, bats, pterosaurs, and insects (though see above for possible independent acquisitions within bird and bat groups). This indicates that the organisms share a common ancestor. Explain the basis for grouping organisms into five kingdoms. Ans: The children of one of these groups: She raised a large family. The three forelimbs are adapted for different functions, but they are formed from similar bones. Types of bipedal movement include walking, running, and hopping.. Few modern species are habitual bipeds whose normal The children of one of these groups: She raised a large family.

Convergent evolution is the independent evolution of similar features in species of different periods or epochs in time. Powered flight has evolved unambiguously only four timesbirds, bats, pterosaurs, and insects (though see above for possible independent acquisitions within bird and bat groups). Plesiosaurus was not a dinosaur.. Dinosaurs were land animals: despite their success, dinosaurs did not conquer the oceans, and only a few dinosaurs (e.g., Spinosaurus) are thought to have had semi-aquatic lifestyles. Birds are vertebrates they have an inner skeleton that contains a spine, limbs, and a skull; This arrangement is assumed by some to be unique to endothermic animals and thus evidence that dinosaurs are endothermic, but such is not the case.

Pterosaurs (/ t r s r, t r o-/; from Greek pteron and sauros, meaning "wing lizard") were flying reptiles of the extinct clade or order Pterosauria.They existed during most of the Mesozoic: from the Late Triassic to the end of the Cretaceous (228 to 66 million years ago).Pterosaurs are the earliest vertebrates known to have evolved powered flight.

Classifying a family of vertebrates as broad and diverse as mammals is a notoriously difficult undertaking. Breathing through lungs. Body is covered with feathers and forelimbs are modified for flying. The vertebrates began evolving that led to the development of mammals. Mammary glands are present which produce milk to nurture young ones. Types of bipedal movement include walking, running, and hopping.. Few modern species are habitual bipeds whose normal Breathing through lungs. The development of a beak has led to evolution of a specially The vertebrates began evolving that led to the development of mammals. A greater number of living amphibian species spawn egg strings that resemble those figured here (Duellman and Trueb, 1986).

Spinosaurus (meaning "spine lizard") is a genus of spinosaurid dinosaur that lived in what now is North Africa during the Cenomanian to upper Turonian stages of the Late Cretaceous period, about 99 to 93.5 million years ago. Bog turtles live in mountain bogs and muddy, mossy wetlands.

The genus was known first from Egyptian remains discovered in 1912 and described by German palaeontologist Ernst Stromer in 1915.The original remains Ans: Cetacea (from Latin: cetus, lit. The three forelimbs are adapted for different functions, but they are formed from similar bones. Anatomy (from Ancient Greek (anatom) 'dissection') is the branch of biology concerned with the study of the structure of organisms and their parts. Bipedalism is a form of terrestrial locomotion where an organism moves by means of its two rear limbs or legs.An animal or machine that usually moves in a bipedal manner is known as a biped / b a p d /, meaning 'two feet' (from Latin bis 'double' and pes 'foot').

Human beings are categorized under vertebrates as they possess the vertebral column; For categorization of tetrapods; For Tetrapods, the existence of four limbs is taken into consideration; In the case of mammals, the mammary gland is the required part; Q3. The diameters of both the eggs and surrounding sheaths lie within the vertebrate range. It is an old science, having its beginnings in prehistoric times. Such is the case of the forelimbs of mammals. The type species is G. libratus; the specific epithet "balanced" is the past participle of the Latin verb librare, meaning "to balance"..

The cladistic term for the same phenomenon is homoplasy.The recurrent evolution of flight is a classic Warms blooded animals.

21. the lamprey 22. the Rhesus monkey 23. Facebook Twitter. They were the first vertebrates, and the ancestors of all other vertebrates.

This indicates that the organisms share a common ancestor.

Birds are vertebrates they have an inner skeleton that contains a spine, limbs, and a skull; The genus was known first from Egyptian remains discovered in 1912 and described by German palaeontologist Ernst Stromer in 1915.The original remains Teeth are absent from both the front of the premaxilla (the bone forming the tip of the snout) and the front of the dentary (the toothed bone of the lower jaw). Pterosaurs were not only the first reptiles capable of flight. Its name is derived from the Greek /gorgos ("fierce" or "terrible") and /saurus ("lizard"). Convergent evolution creates analogous structures that have similar form or function but were not present in the last common ancestor of those groups. Gorgosaurus libratus was first described by Lawrence Lambe in 1914. Almost all theropods had varied gait and stance but were all bipedal, including extant ones.

The allelic frequency of a population is the ratio of the copies of one specific allele that share the same form compared to the number of all forms of the allele present in the population.

Warms blooded animals. Extinct theropods bodies were almost upright and the forelimbs greatly reduced in length. Share to social media.

From simple life forms that were unicellular to the development of multicellular organisms gave rise to the vertebrates. Among the mammals, humans are most closely related to primates such as the orangutan. The teeth which are present are usually small and bulbous, ranging from basic conical forms to leaf-like shapes with large

In contrast to gliding, which has evolved more frequently but typically gives rise to only a handful of species, all three extant groups of powered flyers have a huge number of species, suggesting that flight If the hypothesis of common descent is true, then species that share a The cladistic term for the same phenomenon is homoplasy.The recurrent evolution of flight is a classic

'whale' (/ s t e /), from Ancient Greek: , romanized: ktos, lit. Birds are vertebrates they have an inner skeleton that contains a spine, limbs, and a skull; 'huge fish', sea monster) is an infraorder of aquatic mammals that includes whales, dolphins, and porpoises.Key characteristics are their fully aquatic lifestyle, streamlined body shape, often large size and exclusively carnivorous diet. Larger vertebrates (whether reptiles, birds, or mammals) may also have this type of bone.

These forelimbs also varied in different species but had three fingers with claws.

pterosaur, any of the flying reptiles that flourished during all periods (Triassic, Jurassic, and Cretaceous) of the Mesozoic Era (252.2 million to 66 million years ago).

The Class Aves or Birds is just one of the classes of the bigger Kingdom Animalia.The birds share some characteristics with another closely related class Reptiles, but they also have some features that are unique to these fantastic creatures.Let us go through their main traits. Mammals (from Latin mamma 'breast') are a group of vertebrate animals constituting the class Mammalia (/ m m e l i. /), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones.These characteristics distinguish them from reptiles

Pterosaurs (/ t r s r, t r o-/; from Greek pteron and sauros, meaning "wing lizard") were flying reptiles of the extinct clade or order Pterosauria.They existed during most of the Mesozoic: from the Late Triassic to the end of the Cretaceous (228 to 66 million years ago).Pterosaurs are the earliest vertebrates known to have evolved powered flight. They share a common ancestor.

The diameters of both the eggs and surrounding sheaths lie within the vertebrate range. Among extant vertebrates, at least five species within the Teleostei spawn egg ropes or ribbons (Breder and Rosen, 1966). The cladistic term for the same phenomenon is homoplasy.The recurrent evolution of flight is a classic Skin is covered with hairs and has sweat glands and sebaceous glands. These forelimbs also varied in different species but had three fingers with claws. The three forelimbs are adapted for different functions, but they are formed from similar bones. Powered flight has evolved unambiguously only four timesbirds, bats, pterosaurs, and insects (though see above for possible independent acquisitions within bird and bat groups). The allelic frequency of a population is the ratio of the copies of one specific allele that share the same form compared to the number of all forms of the allele present in the population. The skull of aetosaurs is relatively small compared to the body, and is quite distinctive in shape. The skull of aetosaurs is relatively small compared to the body, and is quite distinctive in shape. Mammals (from Latin mamma 'breast') are a group of vertebrate animals constituting the class Mammalia (/ m m e l i. /), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones.These characteristics distinguish them from reptiles Larger vertebrates (whether reptiles, birds, or mammals) may also have this type of bone. Osteons are complex concentric layers of bone surrounding blood vessels in areas where the bone is dense. Classifying a family of vertebrates as broad and diverse as mammals is a notoriously difficult undertaking. This arrangement is assumed by some to be unique to endothermic animals and thus evidence that dinosaurs are endothermic, but such is not the case.

Classifying a family of vertebrates as broad and diverse as mammals is a notoriously difficult undertaking. Bipedalism is a form of terrestrial locomotion where an organism moves by means of its two rear limbs or legs.An animal or machine that usually moves in a bipedal manner is known as a biped / b a p d /, meaning 'two feet' (from Latin bis 'double' and pes 'foot').

Share to social media. Bird anatomy, or the physiological structure of birds' bodies, shows many unique adaptations, mostly aiding flight.Birds have a light skeletal system and light but powerful musculature which, along with circulatory and respiratory systems capable of very high metabolic rates and oxygen supply, permit the bird to fly. The evolution of fish began about 530 million years ago during the Cambrian explosion.It was during this time that the early chordates developed the skull and the vertebral column, leading to the first craniates and vertebrates.The first fish lineages belong to the Agnatha, or jawless fish.Early examples include Haikouichthys.During the late Cambrian, eel-like jawless fish called The four-chambered heart is present. Human beings are categorized under vertebrates as they possess the vertebral column; For categorization of tetrapods; For Tetrapods, the existence of four limbs is taken into consideration; In the case of mammals, the mammary gland is the required part; Q3. They were the first vertebrates, and the ancestors of all other vertebrates. The development of a beak has led to evolution of a specially Anatomy is a branch of natural science which deals with the structural organization of living things.

Such is the case of the forelimbs of mammals. Unlike other classes of animals, female mammals produce milk to nourish their young. pterosaur, any of the flying reptiles that flourished during all periods (Triassic, Jurassic, and Cretaceous) of the Mesozoic Era (252.2 million to 66 million years ago). Although pterosaurs are not dinosaurs, both are archosaurs, or ruling reptiles, a group to which birds and crocodiles also belong.

A fundamental social group in society typically consisting of one or two parents and their children. Examples: Sparrow, Eagle, Crow, Parrot; Mammalia. 21. the lamprey 22. the Rhesus monkey 23.

One of the strongest evidences for common descent comes from gene sequences. Pterosaurs were not only the first reptiles capable of flight. pterosaur, any of the flying reptiles that flourished during all periods (Triassic, Jurassic, and Cretaceous) of the Mesozoic Era (252.2 million to 66 million years ago). Abstract: Only two ornithomimid genera, Ornithomimus and Struthiomimus , are currently known from the Upper Cretaceous of North America.However, a number of ornithomimid elements from Albertas Dinosaur Park Formation (Upper Campanian), cannot be assigned to either Ornithomimus or Struthiomimus .These bones, including a frontal, caudal vertebrae, and

The family to which human beings belong is called Hominidae.

Dinosaurs did, however, share the Mesozoic world with large, fully-aquatic, ocean reptiles such as plesiosaurs, ichthyosaurs and, from the Late Cretaceous, mosasaurs. Vampire bats, species of the subfamily Desmodontinae, are leaf-nosed bats found in Central and South America. Vampire bats, species of the subfamily Desmodontinae, are leaf-nosed bats found in Central and South America.
