The specimen displays the characteristic anatomy of the species, with clearly visible cephalon, articulated thoracic segments, and pygidium. The trilobite is naturally preserved within the original matrix, giving the fossil an authentic geological appearance while enhancing its three-dimensional relief. Fine ribbing and segmentation remain well defined, highlighting the structure of the ancient exoskeleton. The dark fossil contrasts nicely with the lighter limestone matrix, creating a visually appealing presentation typical of trilobites from this formation. Elrathia kingi is one of the most iconic trilobite species from the Cambrian Wheeler and Marjum formations, making it a classic and recognizable specimen among fossil collectors. A clean and aesthetically pleasing trilobite, suitable both for fossil collectors and as an attractive natural history display piece. Display stand included (as shown in the photographs).
