1.5" Diademaproetus Trilobite - Multi-Colored Shell
This is a beautifully preserved and prepared, 1.5" long specimen of Diademaproetus antatlasius from Ofaten, Morocco. This elengant species features long swept back genal spines and a distinctive rostrum. The trilobite has a naturally, multi-colored shell which sometimes is seen on trilobites from this location. Both of the genal spines have been prepared free-standing.
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 currently described species, filling nearly every evolutionary niche. Due in large part to a hard exoskeleton (shell), they left an excellent fossil record.
