When archaeologists make an interesting discovery, they often make overly ambitious claims about the value of their finds. The case of the Archaeopteryx is a case in point. The discovery of the first Archaeopteryx fossils made quite an impression on the field of dinosaur studies when researchers proposed that the Archaeopteryx was, in fact, not a dinosaur at all, but was instead, a bird. However, a careful consideration of the physical evidence suggests that such claims may have been made prematurely in that Archaeopteryx fossils have a large number of characteristics that are classic features of dinosaurs, rather than birds. First, when you consider the overall body structure of an Archaeopteryx fossil, you can't fail to notice that all specimens possess a long, tail composed of bony vertebrae. The similarity to the tails of many species of dinosaurs, or to the tails of modern day reptiles for that matter, is obvious. The presence of this type of tail is decidedly not birdlike. Next, careful examination of the mouths of Archaeopteryx reveals a strong kinship to dinosaurs. Specifically, Archaeopteryx had teeth; modern-day birds lack this rather obvious physical trait. The teeth discovered with Archaeopteryx fossils are similar to those of smaller, carnivorous dinosaurs of the same era. A third point to emphasize is perhaps the most convincing of all. According to the analysis of many researchers, Archaeopteryx lacked a key characteristic that most people would consider practically synonymous with the nature of birds: flight. While a casual glance at an Archaeopteryx fossil might leave one with the impression of a generally birdlike shape, a careful analysis of the structure of the wings indicates that Archaeopteryx could not have flown.
Recently, there has been a ton of debate as to the classification of Archaeopteryx. More specifically, in regards to the passage, the writer puts forth the idea that all evidence shows Archaeopteryx was a dinosaur. In the listening passage, the lecturer is quick to point out there are some serious flaws in the writer's claims. In fact, the professor believes that the Archaeopteryx was actually a bird and their body structure shows that fact.
First and foremost, the author of the reading states that the tail of Archaeopteryx shows that this species belonged to dinosaurs. Some professionals in the same field, however, stand in firm opposition to this claim. In the listening, for example, the professor states that Archaeopteryx weighed one to two pounds, similar to the penguin's weight. He adds that the compact size of Archaeopteryx indicates that they should be classified as birds, not dinosaurs.
One group of scholars, represented by the writer, thinks that the presence of the teeth in Archaeopteryx's mouth indicates that they might be dinosaurs. Of course, though, not all experts in the field believe this is accurate. Again the speaker addresses this point when he states that the head and the mouth of Archaeopteryx are strong evidence that they should be classified as birds. He elaborates that Archaeopteryx's mouth was long and pointed and looked exactly like a peak, and the development of a peak always means that the species was a bird.
Finally, the author wraps his argument by posting that the analysis of wings' structure indicates that Archaeopteryx could not fly from one place to another.
Not surprisingly, the lecturer takes issue with his claim by contending that Archaeopteryx's wings were covered with feathers. He states that the primary characteristic of birds is the feather on the wings.
To sum up, the writer and professor hold conflicting views about Archaeopteryx's classification. It is clear that they will have trouble finding common ground on this issue
