Similarities And Differences Between Rusingoryx And Hadrosaur Dinosaurs

I will determine whether [æ] and [eʌ] appear to be allophonic or contrastive by examining those target sounds in “Dataset B” and “Dataset A”. Both sounds are present in the datasets but they are never seen together in the same word. The environments of the sounds are determined in (i) and organized by sound to see if there are any patterns that arise.

Researchers believe that dinosaurs shrunk in size while adapting to new changes in the environment. Researchers believe birds descended from two-legged dinosaurs, Theropods. The skull itself is believed to have gone from a Velociraptor, to Archaeopteryx, to modern day chickens and pigeons. Some differences from the Archaeopteryx and chicken are the size of the brain, eye cavities, and beak. The Archaeoptreryx had teeth, where as the chicken does not.

Phonology – use of sounds and how sounds are organized and used in natural languages.

The teeth analyzed in the study were from eight different localities in Spain, including Treviño County, Huesca, Lerida, and Laño. Though two species of theropod were already known, the researchers happened across six additional species during their research on dinosaur evolution at the final stages of the Cretaceous period.

However, some of these injuries do not match with the size and shape of a tooth. Another interpretation is that these lesions came from claws. Claws have not been thought to have caused these injuries because they are made of keratin, which is softer than bone. It would not seem likely then that claws would able to penetrate bone. This was disproved by testing whether tiger claws could damage bone. Tigers were provided an enrichment activity that only exposed their claws to bones bolted to a log. It was shown that tigers were able to scratch and puncture the bones. Substantial evidence of clawing is seen in the T. rex specimen “Peck” (MOR 980). A Tyrannosaurus claw aligns perfectly with the hole in this specimen’s mandible. The reexamination of these specimens indicate that these tyrannosaurs were not only attacked with manual claws but also pedal claws. This conclusion was established by comparing the size and shape of these holes to manual and pedal claws. Further evidence of aggression is supported by stress fractures in the metacarpal and phalanx of tyrannosaurs. These stress fractures may indicate that tyrannosaurs were frequently fighting with one another (Rothschild,

Both the passage and the lecture talk about the dinosaurs survived during the wintertime by migration. The writer supports the idea that the dinosaurs like the Edmontosaurus could survived by the migration while the professor holds the opposite idea.

A study conducted in Alberta, Canada, has identified a new dinosaur species, Ornithomimus (Science Daily, 2015). This discovery, made by an undergraduate paleontology student, unveiled a species with soft tissue as well as preserved tail feathers (Science Daily, 2015). Learning about the existence of this particular species has helped fill in unknown gaps about the convergent evolution between dinosaurs and ostriches (Science Daily, 2015). Due to sediment compaction, the obtained evidence of the feathers was crushed, however, by using technology, researchers determined a three-dimensional keratin structure to the feathers on the tail and body of the species (Science Daily, 2015).

The reading passage states that paleontologists intentionally split a fossilized bone of a 70 million-year-old dinosaur, called T-Rex, and discovered several substances that might be the original tissue of the dinosaur, such as blood vessels, red blood cells, and collagen. However, the lecturer casts doubt on it and provides conclusive evidence to support his statement.

The actual evolutionary origin of the hadrosaurs first began in the late cretaceous period roughly 70 million years ago. These dinosaurs “were members of the Ornithopoda, and close relatives and possible descendants of iguanodontid dinosaurs.” (Carroll, R.L. 1988). They lived in a variety of different environments which led to theories of why hadrosaurs had a crest shaped head piece. Some of these theories included the headgear being used as a snorkel, reservoir for warming air to breathe, and even farfetched theories such as fire breathing. These theories would only be possible through finding evidence of hadrosaurs, such as studying their remains. Luckily, hadrosaurs have a “large number in fossil records for many areas that they often appear in 75% of the dinosaur biomass in a region” as the population of them was also large. Most came and were found in Asia, Europe, and North America and began to be preserved during the cretaceous

Joseph Tyrell made the first significant dinosaur discovery as the leader of his first expedition to find coal. He found Alberta’s “. . . first good dinosaur specimen – the skull of an Albertosaurus on June 9th, 1884.” (Tanke and Currie, 1198). The skull was very damaged by the extraction because Tyrell and his team were not paleontologists and had no experience in digging or preserving fossils. They did not even have the correct tools.

Tim Elam informed us about dinosaurs being similar worldwide, with evidence of fossils, because the land was one at that time. Through time and division of land they began to adapt and change slightly.

Jurassic Park by Michael Crichton demonstrated many dinosaur characteristics and behaviors. The dinosaurs were fictionally characterized to appeal to the readers. By examining the dinosaur’s appearance and behaviors of dinosaurs such as the duckbilled dinosaur, velociraptor, hypsilophodontids, dilophosaurs, Triceratops, apatosaurs, Tyrannosaurus rex, stegosaurs, and maiasaurs distinguished whether the evidence existed in the field of paleontology. The behaviors and characteristics of the dinosaur are divided into three factors as behaviors that were supported, not supported, and no evidence to support or refute the behavior.

Further ambiguity was found in the transcription for the word “urge” as to our untrained, English ears the two vowels sounded relatively similar with the second vowel being longer. (approximately 2-3x longer according to the oscillogram/spectrogram) However upon further prospection of the formants, we found that the F2 of the second vowel in “urge” was slightly smaller (by ~150-200 Hz), which put it at about the same F2 value of the [ʉ] in “gold,” and according to vowel charts [ø] is directly below [ʉ]. Due to the presence of the [ø] and [e] phones in Norwegian,

Therefore, SLM predicts that when a new phonetic category is established for an L2 sound that is close to an L1 sound,

Every language constitutes its own sound system, and this sound system is a very important aspect when learning or studying a language. Along with this sound system are the prosodic features of a language. This study is about the phonological system and the prosodic features of
