Is it metal? What does the other side look like? Dimensions?

Looks like a Sand Dollar fossil in a rock to me?

Yes, older style of sand dollar. Some of them were pretty big and fat, not flat.

I think it's something else . Starfish , sand dollars , and urchins have 5 points , not 7 .

I agree. Although it’s only a colloquial name, not a scientific name, “sand dollar” would in any case be incorrect even if it were an urchin. The name apples to extremely flattened members from the order Clypeasteroida. There are some less flat members of the order generally known as “sea biscuits” but the form is not correct for either type.

It might still be a member of Echinodermata (which includes urchins, starfish, sea cucumbers, crinoids and others) since the symmetry is not always pentaradial but I don’t think there are any urchins with ambulacral grooves that aren’t multiples of five.

There are some species of starfish that have seven arms (Luidia ciliaris for example) and other Luidia species may have other numbers, including nine and twelve. Or it may not be an echinoderm at all.

How big is it?
