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 the rostrum is more shovel like instead of having 3 prongs, and many of the spines are longer. This species just appeared on the market in the couple years and I'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 piece is excellent. Clean eye facets in both eyes and dozens of free standing spines. Only about 1% shell restoration along repaired cracks.
