This is a nice Gerastos granulosus from the Devonian of Morocco. This trilobite was acquired from the Eugene Thomas Collection. This trilobite is nicely articulated and exhibits very good detail. Both free cheeks are intact, the pustulose nature of the large glabella is quite evident, and the eyes are easily seen. The black color of the bug contrasts wonderfully with the light-grey matrix. The fossil is well presented on the sculpted block of dense limestone. This is a fine example of a complete Gerastos granulosus from the Atlas Mountains.
