1. Glycymeris (ID is in URL)
2. Platystrophia (ID is in URL)
3. Epifaunal, Infaunal (respectively)
4. IDK what you mean...Glycymeris is a bivalve and Platystrophia is a brachiopod (They're in different phylums so idk how you would compare their classes)

Bivalves are bilaterally symmetric, Brachiopods have 1 larger valve(pedicle). Otherwise, its all correct. Your turn
EDIT:wrong person, oops

Oh, you were talking about structural differences...whoops.
I'll post a question later.

Answer
1.By flapping the two valves?
2. Class Anthozoa
3. Scallop, does it even have one besides Heliophyllum, and mammoth.
4. permineralization?
5. B,C,A

Image and questions

1. What is the genus of these specimens?
2. What time range did these invertebrates exist?
3. Would this genus be a good index fossil? Why or why not?

What did this fossil attach to when living?

When did it undergo a selective mass extinction?

Where does the name come from?

Also, does anyone know how to put an image into this? Sorry, I'm new to this.

All correct, but the last one is substrates on the ocean floor. It could also be driftwood.

I assume you mean the first one, not the last one?
