I believe it's the other way around, if I'm not mistaken, with the order of layers R and H swapped.

So like this: R, H, M, F, B, I
Your turn!

Wait, why would you ever go youngest to oldest? That's just not right smh.

I am a duck billed dinosaur who went extinct 76 million years ago.

1)Who am I?
2)Recent studies have suggested that this specimen had 2 genders, one was about ___________ larger in body size than the other.
3)Which gender was larger?
4)Name one of the 2 scientists who classified this organism.
5)Where were the teeth located in this organism? How does this help them eat?

Your turn!
Wouldn't the answer be H, R, M, F, B, I, since the igneous intrusion represented by H juts into the sedimentary rock layer represented by R?

I believe the consensus on the Scioly chat was that you can go ahead and ask a question now

Ok! (sorry about taking so long to respond oops)

1. Compare life before and after the Cambrian Explosion

2. The Marine Mesozoic Revolution was the adaption to what type of predation? Name one example of a predator who exhibited this behavior.

3. What are microbial mats and why are they significant to the Cambrian Substrate Revolution?

2.
Shell-Crushing?, Crinoids
3.
