Insane Devonian Spiny Brachiopod (aff. Echinaurus) Fossil - 3.3"
An incredible amount of preparation work under microscope using airscribes and air abrasives went into this specimen to free all of the spines from the hard limestone surrounding it. This is only the forth specimen I've seen of this brachiopod and is well prepared. Including the spines the specimen is about 3.3" wide, just the shell itself is about 1.4" wide. The white mineral you see on the surface of the brachiopod is natural, not an adhesive or other substance.
