Calymene Update Part 2

A Calymene trilobite I have been prepping for weeks now.  Using a DSLR camera now but it needs a macro lens.  Changes since last update used diluted hydrochloric acid on the limestone around the trilobite to smooth out engraver lines.  Used a Dremel tool with two types of stainless steel brushes to clean limestone out of ridges in thorax.  Also used brush to smooth out engraver lines.  More touch up work using a needle tool and Dremel engraver to remove matrix around cephalon.
