Exceptional, Enrolled Morocops Spinifer - Top Quality!
This is an exceptional specimen if one of the less frequently seen phacopids from Morocco, Morocops spinifer. This species is completely covered in small tubercles. It takes a very skilled preparitor and a lot of time to prepare one without abrading away these tubercles. This specimen is enrolled and left partially embedded in the limestone it was found in creating a display base. It's .95" wide and would have been about 1.8" long if outstretched. A true collector specimen!
Trilobites were a very diverse group of extinct marine arthropods. They first appeared in the fossil record in the Early Cambrian (521 million years ago) and went extinct during the Permian mass extinction (250 million years ago). They were one of the most successful of the early animals on our planet with over 25k described species, filling nearly every evolutionary niche. Due in large part to a hard exoskeleton (shell), they left a excellent fossil record.
