The fauna was dominated by archosaurian reptiles, especially dinosaurs, which were at their most diverse stage.

They survived through the K – T boundary and are currently the most successful and diverse group of living reptiles with more than 6, 000 extant species.

Other types of animals, such as amphibians, reptiles, and most insects, are prohibited altogether.

In the oviparous animals ( all birds, most fishes, amphibians and reptiles ) the ova develop protective layers and pass through the oviduct to the outside of the body.

These were the ancestors to most modern reptiles and the ruling dinosaurs as well as pterosaurs and crocodiles.

Mosasaurs were the most common marine reptiles, with genera including Clidastes and Tylosaurus.

* Diapsida – two fenestrae – most reptiles, including lizards, snakes, crocodilians, dinosaurs and pterosaurs

The cladogram presented here illustrates the " family tree " of reptiles, and follows a simplified version of the relationships found by Laurin and Gauthier ( 1996 ), presented as part of the Tree of Life Web Project, with information on the relationships of the most primitive reptiles after Muller and Reisz ( 2006 ).

Most animals that lay eggs, such as birds and reptiles, including most ovoviviparous species, have an oviduct instead of a uterus.

In amphibians and most reptiles, a double circulatory system is used but the heart is not completely separated into two pumps.

The heart of most reptiles ( except for crocodilians ; see below ) has a similar structure to that of lungfish but, here, the septum is generally much larger.

The lung of most reptiles has a single bronchus running down the centre, from which numerous branches reach out to individual pockets throughout the lungs.

Turtles use their tongues to swallow food, but they cannot, unlike most reptiles, stick out their tongues to catch food.

Crocodiles are more closely related to birds and dinosaurs than to most animals classified as reptiles, the three being included in the group Archosauria (' ruling reptiles ').

In most subsequent forms, many of these early ribs have been lost, and in living amphibians and reptiles, there is great variation in rib structure and number.

In addition to bats, coyotes, ringtails, and spotted skunks are the most numerous riparian predators and prey on invertebrates, rodents, and reptiles.

In most reptiles the perilymphatic duct and lagena are relatively short, and the sensory cells are confined to a small basilar papilla lying between them.

The arrangement of the inner ear in living amphibians is, in most respects, similar to that of reptiles.

In most frogs and toads, it is similar to that of reptiles, but in other amphibians, the middle ear cavity is often absent.

In amphibians and most reptiles, a double circulatory system is used, but the heart is not always completely separated into two pumps.

Peafowl are omnivorous and eat most plant parts, flower petals, seed heads, insects and other arthropods, reptiles, and amphibians.

The duodenum is the first section of the small intestine in most higher vertebrates, including mammals, reptiles, and birds.

Amphibians, reptiles, and birds use the same orifice for excreting liquid and solid wastes, and for copulation and egg-laying ; this orifice is known as the cloaca.

File: TylosaurusDB2. jpg | Tylosaurus was the largest known mosasaur, carnivorous marine reptiles that emerged in the late Cretaceous.

The population of a number of native predatory reptiles has declined, such as the varanid lizards Varanus mertensi, V. mitchelli, and V. panoptes, the land snakes Pseudechis australis and Acanthophis antarcticus, and the crocodile species Crocodylus johnstoni ; in contrast, the population of the agamid lizard Amphibolurus gilberti — known to be a prey item of V. panoptes — has increased.

These included the earliest sauropsid reptiles ( Hylonomus ), and the earliest known synapsid ( Archaeothyris ).

Pteranodon (; from Greek πτερ-" wing " and αν-οδων " toothless ") is a genus of pterosaurs which included some of the largest known flying reptiles, with wingspans over.

Adult male Pteranodon were among the largest pterosaurs, and were the largest flying reptiles known until the late 20th Century, when the giant azhdarchid pterosaurs were discovered.

At least some of these marine reptiles are known to have fed on Pteranodon.

On 10 December 1823, she found the first complete Plesiosaurus, and in 1828 the first British example of the flying reptiles known as pterosaurs, called a flying dragon when it was displayed at the British Museum, followed by a Squaloraja fish skeleton in 1829.

Broom was first known for his study of mammal-like reptiles.

Prehistoric earthworks by mound builder cultures are common in the Midwest, but only in southern Wisconsin, northeast Iowa, and small parts of Minnesota and Illinois exist mounds in the shape of mammals, birds, or reptiles, known as effigies.

In Māori mythology, Tū-te-wehiwehi ( or Tutewehiwehi ) is the father of all reptiles, and is also known as Tu-te-wanawana ( or Māori: Tū-te-wanawana ).

The park ’ s known native fauna includes 34 species of mammals, 89 birds, 17 reptiles, 10 amphibians and three freshwater fish.

The primary food for Great Blue Heron is small fish, though it is also known to opportunistically feed on a wide range of shrimp, crabs, aquatic insects, rodents and other small mammals, amphibians, reptiles, and small birds.

In the wild, kookaburras are known to eat the young of other birds and snakes, and insects and small reptiles and even other small birds, such as finches if they are lucky enough to catch them.

It lived in North America during the Mesozoic era, also known as the " age of the reptiles.

The Rufous Treepie is an arboreal omnivore feeding almost completely in trees on fruits, seeds, invertebrates, small reptiles and the eggs and young of birds ; it has also been known to take flesh from recently killed carcasses.

The best known residents are the giant pandas, but the Zoo is also home to birds, great apes, big cats, asian elephants, insects, amphibians, reptiles, aquatic animals, small mammals and many more.

They have been known to consume a variety of animals including rodents, eggs, birds, reptiles, amphibians, and invertebrates.

Mammals are also known to consume reptiles.

Hahnia is a poorly known genus of meat-eating mammal-like reptiles ( Therapsids ) that lived during the Upper Triassic in Europe.

It shows shows the progression of evolution in fossil fish, and amphibians and reptiles through comparative anatomy, including a list of all the ( then ) known fossil vertebrate genera.

The corpus callosum is found only in placental mammals ( the eutherians ), while it is absent in monotremes and marsupials, as well as other vertebrates such as birds, reptiles, amphibians and fish ( other groups do have other brain structures that allow for communication between the two hemispheres, such as the anterior commissure, which serves as the primary mode of interhemispheric communication in marsupials, and which carries all the commissural fibers arising from the neocortex ( also known as the neopallium ), whereas in placental mammals the anterior commissure carries only some of these fibers ).

Unlike the mammalian and bird malarias those species ( more than 90 currently known ) that infect reptiles have been more difficult to classify.

Within the boundaries of the park, the following number of species are known to live: 53 species of mammals, 272 species of birds, 31 species of reptiles and amphibians, 54 species of fish, about 7000 species of insects, over 1000 species of plants, and over 1000 species of fungi.
