this is what it looks like. I'm so bad at this and don't understand it. Help meeee!

Layer W is the same age as Layer Q, because they both have the same fossils.
Layer X appears to have existed in the past and eroded, because it only shows up once.
Layer Z is the same age as Layer R, because they both have the same fossils.
Layer S is the oldest layer, because it is on the bottom.
