Ornithopod Dinosaurs Evolution and Behavior

In their own way, ornithopods—the small, mostly two-legged herbivorous dinosaurs of the Mesozoic Era—have had a disproportionate impact on the history of paleontology. By a geographical fluke, many of the dinosaurs dug up in Europe in the early 19th century happened to be ornithopods (the most noteworthy being Iguanodon), and today more ornithopods are named after famous paleontologists than any other kinds of dinosaur. Ornithopods (the name is Greek for bird-footed) are one of the classes of ornithischian (bird-hipped) dinosaurs, the others being pachycephalosaurs, stegosaurs, ankylosaurs and ceratopsians. The most well-known subgroup of ornithopods are the hadrosaurs, or duck-billed dinosaurs, which are discussed in a separate article; this piece focuses on the smaller, non-hadrosaur ornithopods. Technically speaking, ornithopods (including hadrosaurs) were plant-eating dinosaurs with bird-shaped hips, three- or four-toed feet, powerful teeth and jaws, and a lack of the anatomical extras (armor plating, thickened skulls, clubbed tails, etc.) found on other ornithischian dinosaurs. The earliest ornithopods were exclusively bipedal, but the larger species of the Cretaceous period spent most of their time on all fours (though its conjectured that they could run on two feet if they had to get away in a hurry). Ornithopod Behavior and Habitats Paleontologists often find it helpful to infer the behavior of long-extinct dinosaurs from the modern creatures they most resemble. In that respect, the modern analogs of ancient ornithopods seem to be herbivorous mammals like deer, bison, and wildebeests. Since they were relatively low on the food chain, its believed that most genera of ornithopods roamed the plains and woodlands in herds of hundreds or thousands, to better protect themselves from raptors and tyrannosaurs, and its also likely that they took care of their hatchlings until they were able to fend for themselves. Ornithopods were widespread geographically; fossils have been dug up on every continent except Antarctica. Paleontologists have noted some regional differences between genera: for example, Leaellynasaura and Qantassaurus, which both lived in near-Antarctic Australia, had unusually large eyes, presumably to make the most of the limited sunlight, while the north African Ouranosaurus may have sported a camel-like hump to help it through the parched summer months. As with many types of dinosaurs, our state of knowledge about ornithopods is constantly changing. For example, recent years have seen the discovery of two enormous genera, Lanzhousaurus and Lurdusaurus, which lived in mid-Cretaceous Asia and Africa, respectively. These dinosaurs weighed about 5 or 6 tons each, making them the heaviest ornithopods until the evolution of plus-sized hadrosaurs in the later Cretaceous--an unexpected development that has caused scientists to revise their views of ornithopod evolution. Ornithopod Controversies As noted above, ornithopods featured prominently in the early development of paleontology, thanks to the fact that an unusual number of Iguanodon specimens (or herbivores that closely resembled Iguanodon) wound up fossilized in the British Isles. In fact, Iguanodon was only the second dinosaur ever to be officially named (the first was Megalosaurus), one unintended consequence being that subsequent Iguanodon-like remains were assigned to that genus, whether they belonged there or not. To this day, paleontologists are still undoing the damage. An entire book could be written about the slow, laborious untangling of the various species of Iguanodon, but suffice it to say that new genera are still being coined to make room for the reshuffling. For example, the genus Mantellisaurus was created as recently as 2006, based on its obvious differences from Iguanodon (to which its still closely related, of course). Mantellisaurus evokes another long-standing fracas in the hallowed halls of paleontology. This ornithopod was named after Gideon Mantell, whose original discovery of Iguanodon in 1822 was appropriated by the egotistical Richard Owen. Today, Owen has no dinosaurs bearing his name, but Mantells eponymous ornithopod goes a long way toward correcting a historical injustice. The naming of small ornithopods also figures in another famous paleontological feud. During their lifetimes, Edward Drinker Cope and Othniel C. Marsh were mortal enemies, the result of an Elasmosaurus head being placed on its tail rather than its neck (dont ask). Today, both of these paleontologists have been immortalized in ornithopod form—Drinker and Othnielia—but theres some suspicion that these dinosaurs may actually have been two species of the same genus! Finally, there is now solid evidence that at least some ornithopods—including the late Jurassic Tianyulong and Kulindadromeus—had feathers. What this means, vis-a-vis feathered theropods, is anyones guess; perhaps ornithopods, like their meat-eating cousins, possessed warm-blooded metabolisms and needed to be insulated from the cold.

Feminism Is An Entire World View Or Gestalt, Not Just A...

â€Å"Feminism is an entire world view or gestalt, not just a laundry list of women’s issues.† (Bunch, 1979:9) A critical quest for feminisms is the development of theories and analyses of power. One only needs to start analyzing the material of historical theorists to identify that there exists the need for feminist theories of power. Feminist contributions throughout history have been typically assumed much more utilitarian in their approach. The focus of historical theorists might often be described as more elusive and often entrenched within the patriarchal systems as opposed to rebelling against them, often adhering within the paradigm of systematic power instead of directly challenging the pervasiveness of power itself. Nonetheless, historical efforts have helped establish the need for contemporary feminisms to interrogate and challenge systematic power. Power has different manifestations whether systemic or hierarchical which can be viewed through a feminist critique. Several influential feminist scholars, including Mary Wollstonecraft, Simone DeBeauvoir, and Audre Lourde to name but a few help gain a deeper comprehension of the issue. It is evident that the manifestation of power has affected historical education, law, social training, and language. Education has often been used as a tool to facilitate power. Who has been provided with an opportunity to pursue an education is interesting to analyze. Historically, women and racial minority men were not provided with

Journey Essay Free Essays

English Speech- Journeys â€Å"To travel hopefully is a better thing than to arrive. † In other words a journey and the experiences you have are better than the actual destination. The novel â€Å"The Adventures of Huckleberry Finn† by Mark Twain and the poem â€Å"The Road Not Taken† by Robert Frost have taught me that journeys may involves barriers and hardships, they can lead to significant personal change and more importantly journeys facilitate reflection about how you see yourself, others and the world. We will write a custom essay sample on Journey Essay or any similar topic only for you Order Now Journeys are very important in personal change and growth. They can also help us in comparing and contrasting new and old experiences. Journeys may involve many barriers and hardships and overcoming them can lead to personal change and growth. â€Å"The Adventures of Huckleberry Finn† is an episodic novel that involves the physical and emotional journey Huck and Jim Take down the Mississippi River. Jim is an African American slave who escapes and joins Huck on his adventure. The river symbolises the physical journey they both take and along this journey they discover many barriers and hardships. These barriers and hardships are both emotional and physical. This is evident when Huck is torn between following society’s rules (turning Jim in) or following his heart (helping Jim escape). Huck has come to an obstacle on the journey and has to try and overcome it. He has to make a decision on which ‘path’ he will take. Huck constantly battles with trying to decide what’s wrong from right and asking himself is he doing the right thing. Even though Huck see’s Jim as a friend he still carries on society’s values of racism and prejudice. Twain uses irony and satire to show how society is stupid, racist and oblivious to how they treat others. This is seen when the reward for the capture of Jim is higher than the reward for pap. Society sees that the escape of a slave is far worse than murder. Likewise, â€Å"The Road Not Taken† also demonstrates that journeys may have barriers and hardships. The poem represents how sometimes people who are on life journeys come to a fork in the road or a decision that they have to make. The traveller wants to take both paths but he can’t. He has to weigh up his decision and go with it. Robert Frost uses the path to symbolise the journey the traveller goes on and to create and image for the reader. Repetition and punctuation is also used to create emphasis and to reinforce what has been said. As Robert Frost states ‘Oh I kept the first for another day! Adding and exclamation mark at the end of the sentence. The repetition of the word ‘and’ in the first stanza also adds emphasis. Journeys facilitate reflection about how you see yourself, others and the world. I believe that a journey gives you the opportunity to really see everything in a different light. Journeys may involve obstacles and with these difficulties people experience new situations and therefore change. Whether that be physically, emotionally or psychologically. A journey also assists with the comparison of yourself, others and society. In â€Å"The Adventures of Huckleberry Finn† Huck gets to experience life on a whole new level. He learns how wrong and prejudiced his society Is and how life on the raft is far better in comparison to life on shore. This is shown when Huck is so infatuated with the freedom and care-free nature of life on a raft compared to the cruel, racist and unjust way of life on shore. As Huck states ‘you feel mighty free and easy and comfortable on a raft’. Mark Twain uses juxtaposition and again symbolism to compare and contrast the difference between life on shore vs life on the raft. Twain describes the town life as harsh, dirty and confined in comparison to the life on the shore as care-free, relaxed and independent. This highlights how good life on the raft is. The journey Huck and Jim take allows for both of them to reflect and compare life on shore in comparison to life on the raft. Huck and Jim don’t have to follow society’s rules they are free and with freedom comes opportunity to explore and experience many things they normally wouldn’t get to do. In addition, â€Å"The Road Not Taken† also shows us how journeys allow for our reflection on many things. In the poem the traveller experiences an obstacle or fork in the road. This allows the traveller to take in his surroundings whether that be the path ahead or the people around him. This is shown when he states ‘two roads diverged in a yellow wood’. The traveller has two options and to make a decision he has to really explore both of them. Robert Frost uses this poem to express his belief in not always following the crowd and being an individual. Robert Frost uses conversational language to create a sense of communication between the traveller and the reader and to enlighten the reflection that the traveller has made. After comparing both paths and seeing every option his reflection about his journey changes. The traveller decides to go with the path less travelled. He decides to be different. Journeys can lead to significant personal change. The experiences you have on a journey can shape and change your perception of yourself and the people around you. In ‘The Adventures of Huckleberry Finn’ this is shown when Huck’s beliefs change and he becomes more mature. Huck and Jim’s relationship also develops throughout the journey. Huck’s perception of Jim at the beginning of the journey is very different compared to the end. At the start Huck doesn’t take Jim very seriously and has no compassion or respect for him. The influences of society have taught him that Negro’s are useless and unintelligent. Jim still has feelings and emotions and throughout the journey Huck still feels he has to lower himself to talk to Jim. Huck learns from the experiences they have encountered that Jim is exactly the same as himself. Huck’s beliefs and values change and this is shown when Huck states ‘I do believe he cared just as much for his people as white folks does for their’n. It don’t seem natural, but I reckon it’s so’ Huck eventually notices that Jim is in fact just the same as him. Journeys are very important in shaping, changing and discovering the world around you. â€Å"The Adventures of Huckleberry Finn† and â€Å"The Road Not Taken† have taught me that a journey maybe involve barriers or hardships, a journey can facilitate reflection about yourself, others and the world and lastly a journey can lead to significant personal change.
