Good morning folks. I have another puzzling fossil requiring identification/verification. This fossil came from the Tucson show in 2008 and was thought to be a fossil insect (wasp) nest. There were seven unlabeled fossils in the group I purchased. I have identified five of them but this is one I need your help with. Sounds like china when it's tapped with a spoon and appears to have a small section of fossil tree branch attached to it. Help!
