4" New Trilobite Species (Affinities to Quadrops) - Very Large!

This is a spectacular new species of spiny trilobite from Morocco which appears to have close affinities to Quadrops flexuosa. The main difference is that the rostrum is more shovel-like, instead of having 4 prongs, and many of the spines are longer. This species just appeared on the market in the couple years and we've only been able to acquire a few examples.

It has a reverse arch to it but would be over 4" long if outstretched. The preservation and preparation on this specimen are excellent. Clean eye facets in both eyes and dozens of free standing spines. Only about 1% shell restoration along repaired cracks.

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.
