Skeletal. Brain. Behavioral. Behavioral. Behavioral. Behavioral. These three things are stated in the text "Shedding Light on the Dinosaur-Bird Connection." The text uses various classifications of evidence to attempt to prove the claim birds are living dinosaurs. In the text "Shedding Light on the Dinosaur-Bird Connection," it claims that birds are living dinosaurs because of skeletal evidence. Exemplifying "[m]any similarities can be found when comparing a skeleton of a living bird to the fossilized skeleton of a non-bird theropod, like Sinornithosaurus. They both have a hole in the hipbone, a feature that distinguishes most dinosaurs from all other animals. This feature allows an animal to stand erect, with its legs directly beneath its body. All theropod dinosaurs, including birds, have a fused clavicle bone called a furcula, also …show more content…
Discussing "[w]hen scientists look at non-bird theropod fossils they see evidence of behaviors that are common to living birds, such as nest-building, egg-laying, and brooding. These behaviors were first observed when, in 1993, an expedition to the Gobi Desert in Mongolia made an amazing discovery. Scientists unearthed a Citipati fossil brooding a cluster of eggs. Its limbs folded back against its body. It is one of the few fossils ever found that demonstrates behavior—in this case, parental care. It shows that the behavior of brooding the nests that we see all around us today in living birds was already present in the non-bird ancestors of birds." Additionally, this proves that living birds share some of the same behavioral characteristics as dinosaurs. To stay on topic, the text uses expert, factual, history, and example, which is sufficient to prove his claim. The text unquestionably has no flaws, it gives numerous amounts of evidence to understand, which means the text has no gaps to
Ceratopsians and Pachycephalosaurs Around 144 million years ago, began the emergence of the Ornithischian dinosaurs during the Cretaceous period and diversified into North America and Asia. Ornithischians were classified as having a hip structure similar to that of birds, although they are not the descendants of birds. Marginocephalians, meaning "fringed heads" are a group of Ornithischians that have a distinctive skull structure, consisting of a slight shelf or bony frill on the back of the skull, a unique palate, and a short hip structure. These herbivores include two major groups: the Ceratopsians and the Pachcephalosaurians. These plant-eaters include the Ceratopsians, horned dinosaurs such as the Triceratops, Styrachosaurus, Pentaceratops, and the Protoceratops.
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,

Raymond Rogers, David Krause, and Kristina Curry Rogers found significant evidence that the carnivorous dinosaur, Majungatholus atopus, was also a cannibal (Krause et al 2003). The dinosaur remains of the Majungatholus atopus were dated in the late Cretaceous Period from 65 to 70 million years ago. The Majungatholus atopus inhabited the plains of the northwestern Madagascar and bones and teeth continue to be found throughout the Maevarno Formation and within the channel-belt deposits of the Anembalemba Member. The Majungatholus is commonly found, along with other vertebra taxa in ‘bonebeds’ in the Madagascar area, which is probably the reason this dinosaur is still preserved. The trio discovered teeth marks in many bones of the ribs, ilium, and precaudal axial skeleton co...
The reading states that critics have opposes the idea that Sinosauropteryx was a feathered dinosaur and the author provides three reasons of support. However, the professor explains that critics are unconvincing and refutes each of the authors' reasons.
The female moves her head within the avenue walls during the male display, providing her with motion parallax depth cues that will conflict with the false depth cues of forced perspective.
...ories of why dinosaurs went extinct abound, and as there is no theory yet to be truly confirmed as the “right one”, my theory of dinosaur cannibalism is also purely anecdotal. The discovery of the cannibalistic Majungatholus atopus in Madagascar is an important scientific find because it confirms a long-standing theory of cannibalism among certain carnivorous dinosaurs. Behavioral patterns of extinct animals are difficult to establish; however, these bones give authentication to previous unfounded beliefs about the ancient feeding practices of some dinosaurs.
The idea of cloning dinosaurs and other prehistoric life became popularized by the 1992 film Jurassic Park (based on Michael Crichton’s 1990 novel). Though it may have sparked new interest into the field of paleontology, it did so with deceiving inaccuracies. However, the technical fallacies of the actual dinosaurs are somewhat forgivable as it added to the film’s dramatic appeal. Velociraptor, as depicted in the film, was about the size of a grown man. In reality, velociraptor came to about the kneecap. Furthermore, velociraptor would more likely have been covered in feathers rather than the lizard-like skin portrayed in the movie. One scene shows velociraptor fogging the window of a door. This is an endothermic or warm blooded trait as it implies the dromaeosaurid’s body temperature is above the temperature of his environment. There is also no evidence of dilophosaurus bearing a neck frill, and brachiosaurus did not have the ability to chew his food in a circular motion (iguanodon was the first dinosaur to develop this technique by acquiring back molars to allow for equine or bovine-like chewing). Fortunately, tyrannosaurus remained very close to his biological authenticity, with the only paleobiological errors stemming from a lack in computer animation such as rudimentary ball and joint programs. However, the erroneous nature of the deoxyribonucle...
Jurassic Park is the story of how one man’s idea puts many lives in danger. With lots of experimentation, scientists who worked for him were able to extract blood from prehistoric mosquitoes and other biting insects caught in amber then examine it for foreign blood cells. After that, they would extract them. Doing that, they could obtain DNA of extinct animals; dinosaurs who have been extinct for millions of years. Through a long process, they could recreate dinosaurs. Jurassic Park is a book full of suspense and horrifying murders. I wouldn’t recommend this book to everyone, but just people who enjoy science fiction and suspense. I also recommend not read Dennis Nedry’s death multiple times because it’s gross and...just gross. But other than that, I would give this five dinosaurs out of five dinosaurs!
In an article entitled Tyrannosaurus was not a fast runner, those experts, John R. Hutchison and Mariano Garcia provide us with a detailed account of a recent study they did. Their study is described in an article entitled Biomechanics: Walking with tyrannosaurs by Andrew A. Biewener. Biewener states that Hutchinson and Garcia, “introduce a new biomechanical approach,” to the question of dinosaur movement and provide an, “a...
Jurassic Park is a science fiction novel written by Michael Crichton which was published in 1990. The book follows a mysterious island that is inhabited by genetically engineered dinosaurs created by a bioengineering firm. The story lets us watch as visitors land on the island at the request of the rich billionaire who owns the island and the bioengineering firm, which is named InGen to revel in the wonder that they have created. We follow all the miss-steps until all is lost and the island has to be destroyed. The novel is one to give us insight into what can happen when we try to play god and foreshadows what possibly could go wrong by taking that next step into genetics that could be considered reckless and dangerous. Crichton lets us in on an evolutionary tale that questions biological genetic advancements and what cost come along with possibly stepping over the moral line of right or wrong. The genetic engineered dinosaurs in Jurassic Park are dangerous and are an ill-advised step into the evolutionary development of our planet. Crichton lets us in on an evolutionary tale that questions biological genetic advancements and what cost come along with possibly stepping over the moral line of right or wrong and how we use knowledge and technology to continue to move forward.
The debate of whether dinosaurs were cold blooded or warm blooded has been ongoing since the beginning of the century. At the turn of the century scientists believed that dinosaurs had long limbs and were fairly slim, supporting the idea of a cold blooded reptile. Recently, however, the bone structure, number or predators to prey, and limb position have suggested a warm blooded species. In addition, the recent discovery of a fossilized dinosaur heart has supported the idea that dinosaurs were a warm blooded species. In this essay, I am going to give supporting evidence of dinosaurs being both warm and cold blooded. I will provide background information on the dinosaur that was discovered and what information it provides scientists.

Juvenal probably had D.H Lawrence's short story "Tickets Please" in mind when he said, "Revenge is sweeter than life itself," because revenge is exactly what Lawrence focuses on in this story (Quoteland). Lawrence writes about how a few women, after having gone through a similar experience, get together and avenge a common enemy, John Thomas Rayner and have fun doing that, because beating Rayner is their sport. By doing so, Lawrence makes it a game betweenn John Rayner, the man, and the opposite sex, comprised of the women. In fact after a certain point the story ceases to be a game between John Rayner and the women, but rather becomes, according to Paul A. Wood, a "Battle of Sexes" (Wood, 77).
Proposals have been made to reclassify the pterosaurs, dinosaurs, and certain other groups out of the class Reptilia into one or more classes of their own. The class Reptilia is divided into 6 to 12 subclasses by different authorities. This includes living and extinct species. In addition, a number of these subclasses are completely extinct.
