Trilobites were among the first arthropods in the world. They represent a phylum of hard shelled creatures with multiple body segments and jointed legs. They make up an extinct class of arthropods (Trilobita), that includes over 15,000 species.
It has been reported that, in the Atlas and Anti-Atlas mountain region of Morocco, four or five new species are discovered every year. This area is considered to be the most diverse and richest source of these ancient sea creatures in the world.

Painting instructions for: Onnia
Matrix: for the matrix we use stains (with solids) from Sherwin Williams. Colors can range from grey to tan or brown and can be blotchy. Whatever you feel will give you a natural looking stone. You may need to expirament until you get something you are satisfied with.
1. Paint entire piece with the color you have chosen (top, sides, and bottom) for the matrix. Make sure that there are no areas which did not get painted.
2. Using a soft rag (an old t-shirt works well), lightly wipe off high points of matrix and trilobite. This should help bring out the details of the matrix. You might want to wear plastic gloves so you don't leave finger prints.
3. Set aside and let dry
Trilobite: for the trilobite we use artist oil paints. Any paints you wish to use should do. It just depends on the final finish you are looking for. Oil or acrylics should work equally well. This one can be painted just black. If you choose to use the small bottles of paint used for model cars and airplanes, I would choose a flat black.
1. Choose a starting point which seems logical to you. Usually a point which will not create a handling problem later on as you progress with your painting. Use mixture of raw sienna and raw umber.
2. Use a fine point artist brush so you can accurately paint the fine detail of the trilobite (#1 through #3 usually work best for me). The important thing here is that they are able to make a fine point at the end, for detail.
3. The first photo above is provided to help you figure out what and how the piece should be painted.
4. You may have to paint both sides of the slender legs and spines or you may be able to accomplish the job by painting just the very top. The choice is yours.
5. In any case you want to make certain the edges are smooth and clean to make it look as realistic as possible.
6. When finished, set piece aside and let dry.
Finish: After the piece has finished drying (this depends upon what types of paint you used), spray the entire piece with a clear matte finish (we use KrylonTM Matte Finish) a couple of times to preserve your paint job.
