This is an extremely displayable plate of trilobites from the Devonian of Morocco. There are ten ''Devil-Horned'' Cyphaspis on this block of limestone. It is very easy to see how this trilobite got its name - there are two spines projecting upward and outward from the front of the head. All of the trilobites are natural to the plate - none have been composited. The bugs are 3-dimensionally preserved and exhibit very good detail. The free cheeks are all intact and tightly attached. The ''horns'' and almost all of the long thoracic spines have been prepared in a free-standing manner for optimal display. The trilobites have excellent color and contrast and are beautifully showcased on the sculpted block of dense limestone. This is a stunning multiple plate of these unusual spiny trilobites captured in a feeding frenzy.
