Quizplus · Accepted Answer

The oldest fossils found so far are about 3.5 billion years old. A is incorrect because that is the age of the Earth, not the oldest fossils. C is incorrect because 250 million years is the age of some dinosaur fossils, not the oldest fossils overall. D is incorrect because 10,000 years is relatively recent in geological time and not even close to the age of the oldest fossils.
