The fossil remains of Sinosauropteryx dinosaur recently discovered in China had a thin layer of outline around its skeletal structure suggesting that it had feathers. But critics state that the most common function of the feathers is to enable flight or to provide insulation. Since flight was not possible because of the enormous structure and weight of the dinosaur and insulation was not possible because of the outline’s position, the outline was not that of feathers but rather of frills.

Which of the following, if true, would, together with the information above, provide the best basis for the claim that the layer of outline is the fossil remains of feathers?

A) There were many other Sinosauropteryx fossils found in Germany that also had the same thin layer of outline.

B) Apart from the above discovery, many scientists believed that Protarchaeopteryx belonging to the same genera as that of Sinosauropteryx had feathers.

C) Many carvings depicting flying dinosaurs especially with structures such as those of Sinosauropteryx were discovered recently.

D) In many animal fossils, fiber from skin tissues form a thin layer of outline around its skeletal structure.

E) The chemical composition revealed that the outline was made of white and orange colors, strongly suggesting the display function of feathers as in peacocks.

bkpolymers1617,

I could use the OE. I got the correct answer, but confirming my reasoning would be helpful!

How are you ?
I am struggling with this question could you please provide your reasoning ?

Thanks

Hi arvind910619,

I am doing well and I would be happy to share my thoughts. I hope you are doing well, too!

The fossil remains of Sinosauropteryx dinosaur recently discovered in China had a thin layer of outline around its skeletal structure suggesting that it had feathers. But critics state that the most common function of the feathers is to enable flight or to provide insulation. Since flight was not possible because of the enormous structure and weight of the dinosaur and insulation was not possible because of the outline’s position, the outline was not that of feathers but rather of frills.

Which of the following, if true, would, together with the information above, provide the best basis for the claim that the layer of outline is the fossil remains of feathers?

A) There were many other Sinosauropteryx fossils found in Germany that also had the same thin layer of outline. -- This says that other Dinos had the same outline. But if that outline had just been skin? This does not confirm for us our beliefs

B) Apart from the above discovery, many scientists believed that Protarchaeopteryx belonging to the same genera as that of Sinosauropteryx had feathers. -- The first contender in my book. It is out of scope because it talks about two distinct species.

C) Many carvings depicting flying dinosaurs especially with structures such as those of Sinosauropteryx were discovered recently. -- Contender #2 in my book. I had some trouble eliminating this one. This says that flying dinos were depicted on walls. These drawings look similar in structure to our dino. But how can we say for sure that it is our dino? It could be a similar looking dino. Further, how do we know the time period of the drawings? What if they had been drawn 50 million years before/after our dino? If this had said a picture of our dino, we would have a strong answer. But given this information, it is impossible to tell if this is our dinosaur.

D) In many animal fossils, fiber from skin tissues form a thin layer of outline around its skeletal structure. -- This weakens our conclusion

E) The chemical composition revealed that the outline was made of white and orange colors, strongly suggesting the display function of feathers as in peacocks. -- Here is your answer. Although it seems to compare Peacocks to a dinosaur, it really isn't! It is comparing the chemical composition of the material to show that it STRONGLY matches a feature of a known species today that has feathers. Because of this, we can infer that the dino did indeed have feathers. Though I am not thrilled, this was the way I justified it. It could be that the colors came from the skin and that the skin was used for display purposes. But given the strong relation, I guess this qualifies as the best of the worst.

Does this help?

test takers should also pay attention to question stem.
A,B,C are out of scope.
question stem helps to choose between D and E. -> E

pigmentation cells in the structures shows the structures were feathers, not collagen, because collagen does not contain pigment

"Since flight was not possible because of the enormous structure and weight of the dinosaur" not all not dinosaurs are big, some like Mei long were small.
