Re: Can anyone help ID this rock?

Lydia -
Does it seem dense/heavy for its size?
It appears to be a septarian nodule. Septaria are found in many places with the most famous found in Utah. Often they have crystalline centers composed of the material which cements the pieces of the host rock together.
