Free trilobite pattern -- Phacops

I went looking for small cross-stitch patterns of trilobites, especially ones that are accurate to actual species, because I'm thinking I want a sampler of trilobites.  The variation in these little fossilized critters is so endless, it will be interesting to see how they'd work set out like the old quaker or vierlande traditional samplers, with lots of motifs that are very similar in general outline, but very very different in the details.  My google-fu is strong, so I found...

None.  Go figure, I guess the community of nerdy, cross-stitching geologists is a small one indeed.

But, not to be deterred, I decided to make my own trilobite patterns.

For those who might not have been paying attention in school that day, trilobites, early arthropods, ruled the seas millions of years ago and went extinct before the dinosaurs even existed.  They were the single most diverse group of organisms that have lived on this earth and ranged in size from a couple feet to only a few millimeters across.   In the interest of science education and encouraging our small community of scienc-y stitchers, I'll post the patterns up here as well.  If you would like to share these freebies with others, please do so, but please forward them here and do not copy or sell the patterns. 

With all that out of the way, here is numero uno, the famous Phacops!

The Phacops genus of trilobites was common about 400 million years ago and is well-known because of their large compound eyes and rounded shape.  Fun fact:  phacops is latin for "lens-face".  Ha!
