Which of these events would most likely result in the creation of large numbers of fossils?

assuming that there are no answer choices, as you did not provide any, I shall say that the most likely result in the creation of a bunch of fossils would be a lot more oil, as the fossil fuel didn't get its name for nothing. there are other possibilities, but without the answer choices this is the best I could do. hope this helps!
