1) Identify the class.
2) Identify what body part this is.
3) When did this class first evolve?
4) Explain the difference between the two types of this class of organisms.

1. Class Echinoidea
2. The chewing apparatus, Aristotle's lantern.
3. Middle Ordovician??
4. One's habitat is below the sediment surface (sand dollars) and the other lived above it (sea urchins).
Two years ago I knew stuff about rocks, minerals, experiments, and ecosystems, yay!
Last year I knew stuff about amphibians, reptiles, freshwater, and more experiments, yay again!
Now I know stuff about oceanography, saltwater, birds, and fossils, yay for the third time!

Yep, your turn, although I would elaborate more on the difference between regular and irregular echinoids.

(The order is in the URL, so you can check your answer if you quote this.)
1. What order is this fossil classified as?
2. What are the names of the three sections of its body?
3. A species in this order is a state fossil. Which state and what species?
4. What are the names of this order's two pairs of eyes?

I'd just like to take a moment to appreciate that we've had three questions on eurypterids already this year. This year's shaping up to look pretty fun.

Yikes, sorry. I didn't realize there were questions on those before (and I honestly only chose the order because of E. remipes and New York.) I'll make a question about something more obscure next time.

Nah, it's fine. It was just a joke. You don't have to choose obscure stuff though—it's kind of nice to start off the season with some common questions so that newcomers can get a feel for the event.

I guess you're right, but having so many questions about one order is a little excessive.
Two years ago I knew stuff about rocks, minerals, experiments, and ecosystems, yay!
Last year I knew stuff about amphibians, reptiles, freshwater, and more experiments, yay again!
Now I know stuff about oceanography, saltwater, birds, and fossils, yay for the third time!
