So the question is about sedimentary rock yeah.

Ammonites are sea creatures with a hard shell.They descended from organisms that date back over 400 millions years.They were first evolved 240 million years ago and became extinct 65 million years ago.

Question: What is the youngest age that the sedimentary rock can be? Explain your answer.



I’m guessing it’s 65million years but i dont know how to explain.....

65 million is correct.

Youngest = most recent

It's kind of strange because geologists tend to figure out the age of the sedimentary rock before they date the fossils. It's weird that it's the other way round in this question.

In any pile of sedimentary strata that has not been disturbed by folding or overturning since accumula- tion, the youngest stratum is at the top and the oldest is at the base

Your answer provided above is indeed correct.
