Insane Devonian Spiny Brachiopod (aff. Echinaurus) Fossil
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 third specimen I've seen of this brachiopod and it is by far the best prepared of the three. Including the spines the specimen is about 3" wide, just the shell itself is about 1.2" wide.
