Answer:
A) the fossil record along the edges of continents
Step-by-step explanation:
if you find the pieces to the same dinosaur fossil on continents that are separated, it means that the fossil used to be living on one massive continent, and when it died, the fossils got burried underground. overtime, the continents drifted apart and the fossil got split, so some of it is still on one continent, and the parts are on another continent.
