Question

Suppose you believe a dinosaur fossil to be 70 million years old based on the type of rock it was found in. What evidence would support this?

A. similar dinosaur fossils dating to 65 million years ago
B. different dinosaur fossils dating to 65 million years ago
C. radiometric dating of the rock layer in which the fossil was found to 70 million years ago
D. radiometric dating of fossils of different dinosaurs found several miles away to 70 million years ago

Answer 1

c

Step-by-step explanation:

Answer 2

C. radiometric dating of the rock layer in which the fossil was found to 70 million years ago

Step-by-step explanation:

Since the estimation was based on the rock that was found around the dinosaur, then the best way of supporting the above claim would be radiometric dating of the rock layer in question.

Radiometric dating is a scientific dating technique used to date materials such as rocks and carbon where trace radioactive impurities were selectively incorporated when they were formed.

Thereby our answer shall be C.
