Diademoproetus praecursor

Diademaproetus sp., a Devonian trilobite from Morocco, is similar to Cornuproetus in size and shape, but with a few morphological differences. The anterior border of Diademaproetus is elongated forming a 'tongue' or a sub-triangular cephalic process, whereas in Cornuproetus the glabella is rounded. The genal spines are long sometimes reaching the distal part of the pygidium. Both Diademaproetus and Cornuproetus have holochroal eye lenses.

The trilobite has been liberated from its matrix so it appears to be suspended in air. The trilobite measures 1.20 inches long and 1.0 inches wide. The matrix measures 2.0 inches long , 2.0 inches wide and 1.1 inches high.

The trilobite has been repaired across the cephalon and through the base of the left genal spine.

This trilobite cannot be mailed internationally.
