Is this a geode?

Found this in the creek right acrossed the road from my house. Found some fossils too, does anyone know where I can post them, Thanks.

Yup...at least part of a geode cavity. Nice find. Some people call those rounded shapes "turtleback"

Scroll down the main forum page. The block below the civil war has a fossil and rock/gem category.
