Next to the ceratarges, the other smaller trilobite on the side was probably one of the drotops. Due to the fact that its head is mostly inside the matrix, making it hard to tell the exact. By examining the matrix, it seems that the two specimens are probably artistically put together. The two pieces are merged in a very skillful way, and the line is almost seamless, giving an impression of a small crack in the original matrix.
This is a spiny trilobite from Morocoo. It is Ceratarges sp. from the Devonian period. The three-dimensionally preserved trilobite has many long, sweeping spines. The bug has extended genal spines and two pair of broad, flowing spines emanating from the pygidium. Its pair of long curving “horns” and its stalking eyes are there, but are not completely free from the matrix. The bug has thick, dark exoskeleton that contrasts with the light-colored matrix.
The matrix is about 3.5 inches in diameter and weights 10.7 oz. The bug is about 1.375 from the tip of its nose to the end of its spines.
