Cryptolithus Drawing Version 2

Using Adobe Illustrator and then touching up with Adobe Photoshop I created a second version of yesterday's drawing. The thorax and pygidium have been redrawn. The right side of the lace collar was mirrored and the lines of the outer rim of the cephalon adjusted. Shading was added in an attempt to create depth for the cephalong and glabella.

Cryptolithus Trilobite Diagram

Here is a quick rendition of a Cryptolithus trilobite from the Ordovician Period. I needed to make a label for a fossil I was sending out. I took some artistic license with holes in the lace collar, the deformed glabella, and the warped looking thorax segments. Probably when digitally composing a trilobite, it is a good idea to do either the right or left half and then reflect it along the y-axis.
