Which statement should Marley use to support her scientific explanation? Options: I have shared my thoughts with other scientists who seem to agree with my explanation. Based on my knowledge and experience at the Natural History Museum and the age of this bone, I would argue that it belonged to a flying dinosaur. After reviewing our results, and comparing it to the research conducted by other scientists, the evidence supports the possibility that the bone belonged to a flying dinosaur. In my observation, I noticed that the bone was hollow. I remember learning in college that birds have hollow bones, and considering the age of the bone I believe that the fossil belongs to a flying dinosaur.
