Are birds really dinosaurs or are they simply related? That is a question that has gained new life in recent years due to the overwhelming facts the are pouring in from newly found fossils and studies from fossils that have been found in the past. Two groups have formed in the study of this question: those who believe birds are a direct result of dinosaurs and those who feel dinosaurs and birds must have had a common ancestor. Determining which view is correct is a matter of opinion based on fact. The main problem involves the use of cladistics or phylogenetic systematics to group organisms according to characteristics they share. When one looks at dinosaur fossils, he or she may feel that certain characteristics are used for something entirely different than someone else who has looked at the same fossil.
One cannot talk about dinosaur and bird lineage without mentioning Archaeopteryx. Most paleontologists agree that Archaeopteryx was the first bird. Archaeopteryx thus represents what paleontologists would call a “transitional form” between two major groups of animals, the reptiles (dinosaurs) and birds. The main difference between the theropods and Archaeopteryx were the long arms of the Archaeopteryx, adapted as wings, the feathers, and the presence of a wishbone that the theropods did not have. All of these features tie it to birds and its other characteristics tie it to theropods. One might say it was the “missing link” between the ...

- The Link Between Dinosaurs and Birds There have been many recent discoveries pertaining to the finding of dinosaurs. However, there has never been a link between dinosaurs and birds at least not like this before. There has been a discovery in China of a remarkable dinosaur with birdlike feathers on its hind legs and tail including others places. A man by the name of Henry Gee has been researching this topic since 1996 and has come up with new discoveries. This four-winged dinosaur has fueled debate over evolution of airborne birds....

- The Relation Between Birds and Dinosaurs One question that has stumped many paleontologists for centuries is, “Are birds dinosaurs?” Paleontologists have argued back and forth trying to prove or disprove each side of the theory. So far, advocates have supported their side through the facts of similar bone structures, bone organization, and the idea that dinosaurs had feathers. A common reaction that some people might have about the question is that there is no connection between the two species.... [tags: Paleontology Bones Essays Papers]

- Debating the Connection Between Birds and Dinosaurs We live in a world, where every question must have an answer. If that question doesn’t have an answer, somebody is determined to find out what the answer is. One of those very questions is simply, did birds evolve from dinosaurs. Many scientists have theories. There is no definite answer. I will, however, give you information on some theories scientists have, as well as information on a new discovery that may very well be indeed what scientists around the world have been looking for....

- The Debate Over Birds and Feathered Dinosaurs Because dinosaurs are animals that lived millions of years ago, we are entirely dependent on the fossils that they have left behind for any understanding that we hope to gain. As any paleontologist will tell you, fossil hunting is difficult. There are no certainties, no guarantees. A certain amount of luck is as valuable as any scientific knowledge. Every so often a discovery is made that attempts to shake up pre-conceived notions of how the dinosaurs actually lived or how they came to be.... [tags: Anthropology Essays Paleontology Papers]

- Microraptor: The Missing Link Between Birds and Dinosaurs In December of 2000, three Chinese scientists reported the discovery of the smallest adult dinosaur ever found, a species that claims to tighten the evolutionary gap between dinosaurs and birds. The dinosaur’s specie name is Microraptor, and it is slowly restoring the integrity of a sect of paleontology that was discredited in November of 1999 after National Geographic printed a story on the discovery of a species known as Archeoraptor....

- Chinese Paleontologists Create a False Fossil Link Between Birds and Dinosaurs An article published in January of 2000, “All mixed up over birds and dinosaurs”, by Richard Monastersky in Science News Online seems to put an interesting spin on a corresponding article published about six months earlier in the scientific journal Nature. The article in Science News Online seems to imply that the article “A dromaeosaurid dinosaur with a filamentous integument from the Yixian Formation of China,” could be referring to forged fossils made up by Chinese scientists in order to provide the missing fossil link between birds and dinosaurs....

- Dinosaurs are not extinct As time goes on, more and more fossil record of dinosaurs are richly known; more and more relative research project work on. An encouraging imagination that species of dinosaurs are not extinct and they evolve to birds was emerged. Dinosaurs are still here. They are still all around in the Human Age. It sounds crazy. Nevertheless, it seems clues are everywhere. There is a kind of dinosaurs, call Sauroposeidon, could raise its massive head over eighteen meters into the air, but this was only possible because their neck bones were so light, almost 85% hollow (name)....

- Anywhere you go today you can see birds; Dinosaurs however, not so much. These two types of life look very different, and one of them happens to be extinct. Are the dinosaurs really gone, or have they simply taken on a different look and now soar the sky. Birds and dinosaurs are actually one in the same. The evolutionary link between birds and dinosaurs is that “birds are avian dinosaurs and other dinosaurs are non-avian dinosaurs,” this is shown in the fossil record and the birds that inhabit the earth today ("Are Birds Really Dinosaurs?")....

- “...99.9 per cent of all [species] that have ever existed are now extinct.” (Benton 1) After one hundred and sixty million years of domination, the reign of the dinosaurs ended in fire and ice. Sixty five million years ago, the largest volcanoes in the history of the Earth erupted across what is now India, effectively annihilating the dinosaurs by spewing out noxious gas and ash, that effectively blocked out the sun killing off most vegetation and breaking the food chain, leaving the dinosaurs to starve....

- The prominent theory is that dinosaurs died in a fiery death due to an asteroid crash on Earth, but is that really what caused their mass extinction. Every scientist has a theory, and with so many out there it was hard to just pick one, they all made sense. It is completely possible for a volcano to have killed the dinosaurs, or even an asteroid. Another popular theory was the ice age. These were all plausible reasons for the extinction of dinosaurs, and that’s when the combination theory was discovered....
