Sauropod Dinosaurs Name Institution Date Sauropod is Greek word which means ‘footed like a lizard’. Sauropods were a large species of dinosaurs that were herbivorous in their mode of feeding. They had very unique characteristics that could easily differentiate them from other dinosaurs. Sauropods are known to be the biggest dinosaurs that have ever existed (Klein, 2011). These types of dinosaurs are among the most fascinating creatures that have ever lived. Their extinction was a great loss to humanity. Sauropod dinosaurs were extremely big size. They varied in sizes depending on their age. Young Anchisaurids were 8 feet long while the giant ones like diplodocidis, titanosauris and branchiosaurids grew up to 100 feet (Levin, 2012). With such a huge size, they required large amounts of feed to maintain themselves. Drinking large volumes of water was also important. Due to the competition that presented itself naturally in the wild, Sauropods were well adapted in all aspects so that they would maintain their survival. As plant eaters, sauropods were adapted with very long necks. Mamenchisaurus had the longest neck which was about 50 feet long, more than half of its body length (Thomas, 2011). The neck length also varied from one sauropod to another. Sauropods such as Sauroposeidon and Brachiosaurus (the Brachiosaurids) had necks that were vertically positioned like that of the giraffe. In addition, other sauropods had necks that were horizontal-like and parallel to the ground. An example of that type of sauropod is the diplodocus. Long necks were important for them to reach the leaves that were high on the trees (Levin, 2012). They could be able to poke trees in order to obtain foliage that was very unavailable becaus... ... middle of paper ... ...r of all dinosaurs (Thomas, 2011). It is believed that on the sixth day there were all sorts of dinosaurs, many different types hence proving that the prosauropod were only but a different type of dinosaurs. People also believe that the Bible refers the sauropods as the beast of the earth. The remains of these dinosaurs were found on every continent except Antarctica thus proving that they were very widespread. Sauropods had the most long lived life span when compared to other animals. Their existence expanded up to 100 million years. This was a very long time, especially for such a large animal to maintain itself (Klein, 2011). However, after many years, they began to die one by one due to the challenges that presented themselves in the wild. For example, vegetation became scarce. They began to starve and became an easier prey to predators. Eventually, this led to
Around 144 million years ago, began the emergence of the Ornithischian dinosaurs during the cretaceous period and diversified into North America and Asia.
My partner and I researched the amazing dinosaur called the velociraptor. Velociraptors are a dinosaur that has many similar features as a common turkey. For example, this dinosaurs had feathers, but not covered completely like a turkey. They are about 2 and a half feet tall with hollow bones. Like most birds, they have a wishbone and talon feet. They also had quill knobs. They couldn’t fly because they were too small, but they used them to hunt. They had long thin tall to help them balance when they were running. Their strong legs helped the run up to 40 miles per hour! Velociraptors were known as one of the top ten most dangerous dinosaurs in their time (the late cretaceous period) because of their sharp claws and sharp curved teeth. These dinosaurs were great hunters, their claw would puncture the flesh of their prey but not rip through it, yet their teeth would. Their teeth and claws helped
The Jurassic environment that Updike constructs in his short tale invites interpretation. First, the majority of the dinosaurs described were found, as one would expect, in the middle to late Jurassic period. By the Cretaceous period, the era that followed the Jurassic, these species had largely faded into obscurity, replaced by huge sauropods. Indeed, the only species in Updike's tale that falls into this class of Cretaceous sauropods are the brontosaurus and the diplodocus, both of which are held in high regard by the narrator. One can clearly infer from this evidence that, though Updike titles hi...
Dinosaurs held their own, according to studies, for at least 150 million years. After becoming extinct and finding fossilized remains dinosaurs have become a way in which we not only measure the changes that have occurred as the planet evolved, but also how we express ourselves today.
They ruled the world before the time of the dinosaurs, from the Cambrian Period to the
As a result of the animals looking the same, they often act the same too. Dinosaurs have been observed to tend to have actions of protection towards what is there, just as people who watch birds would do today. "When 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." (“Shedding Light on the Dinosaur-Bird Connection.”). The author has told us that the dinosaurs have done these actions just as birds do now in the time that current people are able to see and observe.
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.
The Triceratops was living in the late Cretaceous Era. It lived about 68 to 65 million years ago. The Triceratops were said to live in the Wyoming, Colorado, and Canadian area, where they have cold winters. The Tyrannosaurs dominated all of their prey in North America at that time. Also giant penguin-like marine animals called Polycotylid Plesiosaurs appeared in the oceans towards the south. The Earth was still dominated by dinosaurs at that time. During the late Cretaceous Era, North America was slowly moving westwards, whic...

T-rex stood around 12ft tall at the hips, and was 40ft long from head to tail. And weighed around 7 tons, but some scientists today believe it could weigh more, around 9 tons. Its arms were unusually short for its
The dinosaur weighed around 77 tons. This was found to be false upon further investigation and another recalculation of the numbers the dimensions of the colossal dinosaur were shown to be more likely at 69
Dinosaur Fossils in Antarctica Millions and millions of years ago, the continents lay together as one super-continent known as Pangea. As time went on and the plates underneath the Earth began to separate, the continents land moved towards the poles where glaciation occurred. Glaciation is the process in which glaciers were formed during the ice age. Glaciation causes a drop in temperature which in turn causes water to freeze and form many layers of ice (http://palaeo.gly.bris.ac.uk/Palaeofiles/Permian/intro.html, 1). Due to this layering of ice that has occurred at both poles, it has not been easy to discover new dinosaur fossils.
The dinosaur could not have lived for ever. No creatures, no plants, no tiny bacteria are
The Jurassic period is known as one of the most interesting periods of time in earth’s history, mainly for the awe-inspiring creatures many of which have gone extinct, the most remarkable being the dinosaurs. Life in the ocean during this time was also extremely diversified and amazing for the creatures it beheld. The Jurassic occurred from 199.6 to 145.5 million years ago, following the Triassic Period and preceding the Cretaceous Period within the Mesozoic Era. The supercontinent of Pangea began to drift apart during this time. Right before the Jurassic period began, a major extinction event occurred wiping out much of the life on earth. The events that unfolded afterwards gave life to a new planet.
Reptiles are vertebrate, or backboned animals constituting the class Reptilia and are characterized by a combination of features, none of which alone could separate all reptiles from all other animals.The characteristics of reptiles are numerous, therefore can not be explained in great detail in this report. In no special order, the characteristics of reptiles are: cold-bloodedness; the presence of lungs; direct development, without larval forms as in amphibians; a dry skin with scales but not feathers or hair; an amniote egg; internal fertilization; a three or four-chambered heart; two aortic arches (blood vessels) carrying blood from the heart to the body, unlike mammals and birds that only have one; a metanephric kidney; twelve pairs of cranial nerves; and skeletal features such as limbs with usually five clawed fingers or toes, at least two spinal bones associated with the pelvis, a single ball-and-socket connection at the head-neck joint instead of two, as in advanced amphibians and mammals, and an incomplete or complete partition along the roof of the mouth, separating the food and air passageways so that breathing can continue while food is being chewed. These and other traditional defining characteristics of reptiles have been subjected to considerable modification in recent times. The extinct flying reptiles, called pterosaurs or pterodactyls, are now thought to have been warm-blooded and covered with hair. Also, the dinosaurs are also now considered by many authorities to have been warm-blooded. The earliest known bird, archaeopteryx, is now regarded by many to have been a small dinosaur, despite its covering of feathers The extinct ancestors of the mammals, the therapsids, or mammallike reptiles, are also believed to have been warm-blooded and haired.
