1.7" Red Barrandeops Trilobite With Enrolled Specimen

This is a unusual, red Barrandeops granulops trilobite from Hmar Laghdad, Morocco. The shell preservation is a deep red coloration which is very unique to the location. It's 1.7" long which is large for the trilobites from this location and perfectly prone. There is also an enrolled specimen associated with it.
Trilobites are very tough to find complete at the site that produces these red specimens. The red coloration is due to high levels of iron in the silicified exoskeleton. A paper on this unique preservation can be found below.
