Mozerkite? Chert? Banded like agate

*mozarkite

Thanks!

rock

Greetings @elizabeth-henson and @kyle-griffiths! I agree with Kyle that this is a rock, most likely quartz or quartzite (metamorphosed sandstone).

they all look like rocks to me. This might be a nice agate, it looks like some banding might be visible under the skin. if you put it on a strong flashlight it might “glow” as it’s not totally opaque.

Thanks!

Greetings, @elizabeth-henson and @corinne-daycross! I agree that this is only an interesting rock and not a fossil, although it does not fulfill the definition of agate (which is a primarily translucent piece of cryptocrystalline silicate with banding from the incidental elements within).

part of the hinge of ancient Gastropod

Greetings, @mike-steinhorst! I doubt it could be a “hinge of an ancient Gastropod” because this specimen would have a more concavo-convex geometry in addition to a different texture.

Thanks!
