This is a very rare Scutellid trilobite. It is a distinct spiny Thysanopeltis new sp. from Morocco. This type differs from Thysanopeltis speciosa in that the row of spines emanating from the border edge of the pygidium are very long, very thick, and very pointed. This bug showcases this feature beautifully. The inflated trilobite is complete and has both free cheeks intact and tightly articulated. The thick shell exoskeleton is well preserved - the ribs and spines on the tail are wonderfully showcased. This specimen is quite large and nicely showcased on the sculpted matrix block. This is a very displayable and very collectible example of this rare, spiny Scutellid trilobite.
