Geologists discovered many Cenozoic fossiliferous rocks in Virginia's Coastal Plain. A large number of fossil clams, snails and sand dollars can be found in these marine rocks; along with fossilized whale bones and shark teeth. What can you infer is the reason?

What can be inferred as the reason for this is that many Cenozoic fossiliferous rocks in Virginia's Coastal Plain are likely to be coastal Plain sediments, which contain a rich record of Cretaceous and Tertiary continental shelf marine life.

Explanation:

The Coastal Plain sediments contain a rich record of Cretaceous and Tertiary continental shelf marine life. These marine organisms are an interesting contrast to the Paleozoic marine fossils of the Inland Basin and are evidence of the significant changes in sea life over the last several hundred million years. The most common fossils include mollusks (clams, snails and cephalopods), corals, barnacles, and sharks' teeth. The degree of preservation of Coastal Plain fossils varies widely, with many looking much like modern shells.

The correct answer is A) Dramatic changes in sea-level.

Explanation:

the unequal cytoplasmic division that  results  in  one egg  and three polar bodies ensures that a fertilized  egg has  ample nutrients  forits journey  to  the uterus.
