As everyone knows, complete Mississippian trilobites are very rare and highly collectible. This is a top quality example of Hesslerides bufo from the Mississippian of Indiana. This trilobite was collected from the famous Crawfordsville crinoid beds, and was in a major collection for the last ten years. This specimen is complete and very 3-dimensionally preserved. Both free cheeks are present, and the right genal spine was prepared free-standing - amazing!. The chocolate-brown bug contrasts wonderfully with the blue-grey matrix. The trilobite is well showcased on the large block of limey siltstone that also contains a Platyceras gastropod, an Archemedes screw bryozoan, Cladochonus corals, and numerous crinoid fossils. This is a spectacular Hesslerides trilobite that is preserved, as in life, sitting on the Mississippian sea floor bottom.
