Which of the following is usually most helpful in determining the age of these fossils? A. The size of the fossils
B. The color of the fossils
C. The amount of surface area of the rock layer in which the fossils are found
D. The depth of the rock layer in which the fossils are found

D. The depth of the rock layer in which the fossils are found

Explanation:

Size is irrelevant because a t-rex and ancient hamsters lived together

Color is irrelevant, because with time, almost all fossils are a grey tone look

D.) is the better answer between C.) & D.) because layers of the earth are used in the approximation of the time period in which the dinosaur lived

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.

for example, no new evidence will demonstrate that the earth does not orbit around the sun (heliocentric theory), or that living things are not made of cells (cell theory), that matter is not composed of atoms, or that the surface of the earth is not divided into solid plates that have moved over geological timescales .
