Order Monotremata: The defenition of a monotreme is an unusual mammal that lays eggs instead of giving birth to live babies. A few examples are the echidna and the platypus. Their skulls have certain features that resemble reptiles. They have three bodily systems, they have the digestive system, urinary system, and reproductive system. These systems all end up in the same chamber for monotremes called the cloaca. Cloaca means “one hole’’ so it fits perfectly with the monotremes situation. After monotremes give birth they suckle their young after hey hatch out of their eggs. They also have bones like the marsupials called eupubic bones that are connected to the pelvis. The baby monotremes have teeth but they do not go through their gums and real functional teeth are not shown in the adult monotremes. …show more content…
They are covered in fur and in spines. They use their broad feet (which have either three, four, or five claws) for digging. Echidnas are divided into two categories, short-nosed and long-nosed. They hibernate if their food supply begins to decline rapidly, and usually when they wake up from their hibernation, the females are ready to mate. The male echidnas are larger than the female echidnas. They mainly eat bugs and worms and enjoy digging. Platypi are another example of monotremes. They have a bill similar to that of a duck and they are covered with soft, hairless skin. They have streamlined bodies and their tales are similar to the beavers tail except platypi have fur on their tail. Many fossils have been found that ressemble the platypus, but they are mainly fragmentary. Creationists question why platypi would need to be brought onto the Ark because they are semi-aquatic. But the Bible says that it rained for forty days and forty nights, and platypi cannot stay in the water for that long so it is safe to assume that they were on the Ark.
Ana-Mauríne Lara’s Erzulie’s Skirt positions the female body as the scene where lives are interconnected across history and as a dissertation of the human condition. Her protagonists, Micaela and Miriam, tell a story of love, struggle, and survival that echoes the historical significance of slavery and the Caribbean middle passage across time and space. Divided into several sections based on time and location, one particular period in Lara’s novel connects Micaela and Miriam’s experiences most closely with slavery as a whole. After a voyage across the Mona Strait as an attempt to escape from the conditions in the Dominican Republic, they find themselves captured, trapped in a brothel, and forced into prostitution. Many parallels can be drawn to interpret Lara’s use of the brothel as a metaphor for the slave ships used to travel across the original Middle Passage, including the comparable use of people as commodities, the specific imagery and language Lara uses, the historical narrative presented at the beginning of each section, and the larger themes in which identities were simultaneously stripped by oppression and also preserved within the context of community and spirituality.
Claude Monet played an essential role in a development of Impressionism. He created many paintings by capturing powerful art from the world around him. He was born on November 14, 1840, in Paris, France. Later, his family moved to Le Havre, Normandy, France because of his father’s business. Claude Monet did drawings of the nature of Normandy and time spent along the beaches and noticing the nature. As a child, his father had always wanted him to go into the family grocery business, but he was interested in becoming an artist. He was known by people for his charcoal caricatures, this way he made money by selling them by the age of 15. Moreover, Claude went to take drawing lessons with a local artist, but his career in painting had not begun yet. He met artist Eugène Boudin, who became his teacher and taught him to use oil paints.

Ceratopsians and Pachycephalosaurs are closely related in their characteristics. Ceratopsians processed a saddle-shaped boney frill that extended from the skull to the neck and typically had horns over the nose and eyes. The most popular was the triceratops, which could reach over 26 feet and weigh in excess of twelve metric tons. Their frills served as two major functions. It protected the vulnerable neck from being harmed. The second major function that the frill provided was due to the fact that the frill contained a network of blood vessels on its underside, which were used as a means to get rid of excess heat. The Pachycephalosaurs were considered to be bipedal. They were also found to have thick skulls, flattened bodies, and tail that were covered in an array of body rods. Pachycephalosaurs were thought to have been more than fifteen feet long and processed a skull that was surrounded by a rounded dome of solid bone. It was thought that they used their heads in combat or mating contests, but that was disproved fairly recently, which I will discuss later in the paper. Both Ceratopsians and Pachycephalosaurs were “bird-hipped” and both of these suborders contained a backwards pubic bone. Both were Marginocephilia, or “fringed heads”, which is one of three clads under the Orinthiscia order. They were also herbivore dinosaurs that inherited their fringe at the back of the skull from earlier ancestors.(2) Their classi...
If you were to live during the tertiary period, this would be one of the things you would often see. All of the mammals that existed during that time period were terrestrial. They all were land dwelling mammals. Before J. G. M. Thewissen and colleagues’ discovery in Pakistan, many scientists believed, since the constant new discoveries twenty years ago, in what the numerous fossils from North America, Pakistan, and Egypt have revealed, “…these early cetaceans had mobile elbows and external hind limbs with articulated knees. However, they were fully aquatic, except for Ambulocetus, which was amphibious-much like sea lions” (Walking with Whales).
2. Fossils of its pelvis, legs, and feet indicate that it was bipedal, like humans.
It will pay special attention to the similarities of the monotreme reproductive system to those of animals we are more familiar with. Background Monotremes are crepuscular animals only found in Australia and New Guinea.
When someone says the word octopus, an image of an eight legged invertebrate comes to mind. The body structure of a mature octopus is very interesting. Octopuses are extremely intelligent. They have excellent memory can use tools, and are great problem solvers. Only birds and mammals are known to be smarter. Each one of their tentacles, which are used for prying open clam shells, has two rows of suckers that can give them a pretty good grip. An octopus also tastes with its tentacles. An octopus’s third right arm, also called hectocotyli, is also its penis which a male octopus will use to mate at one or two years of age. The only part of an octopus that cannot move or squeeze through small spaces is its beak where it consumes food. This is used for biting and also breaking things apart. Did you know that octopi have three hearts? This is because these sea creatures have extra legs and three hearts are necessary for better bl...
Trilobites are extinct sea creatures that were one of the first forms of life on earth.

extinct for 4000 years, it is difficult to tell exactly what they lived on, but
For instance, the whale, the biggest mammal that lives in the water, was found to have had legs and used to dwell on land millions of years ago. While in Pakistan, Phil Gingrich, a geologist and paleontologist, came across a fossil that resembled that of a wolf but had a “bump” on the back of the skull which was found to part of an inner ear,

along the streams of Eastern Australia in burrows they dig for themselves, and are the only mammal to lay eggs. An adult platypus can be from around 16-22 in. long and have a tail about 4-5 in. long, [1] they are born with spurs on the back of each ankle, but the females lose theirs when they are about 1 year old. On the other hand, male platypus' spurs are connected to poison glands that they use for defense, [1] particularly in the mating season when the poison glands enlarge and are used to compete for females. When the platypus mates, the fertilized eggs will stay in the female's body for about 28 days. [5] The female will then lay the eggs in her burrow using her claoca, an organ used for digestion and reproduction usually found in reptiles or birds [1]. After about 10 days, the baby platypus, or...
