Excellent fossil trilobite specimen, attributed to the genus Crotalocephalina gibbosa, from Morocco. The trilobite displays well-defined thoracic segments, a smooth and compact cephalon, and a rounded pygidium, perfectly closed against the head. Preservation is authentic and three-dimensional, with no evident reconstructions. The fossil shows a dark natural coloration that creates a very attractive contrast with the lighter sedimentary rock matrix, enhancing both its visual impact and display quality.
