Phacops speculator is a classic Devonian Era trilobite from the Atlas formation. The prominent pustulose surface on the glabella and the wonderful compound eyes are features one can never tire of admiring. The trilobite has its tail curled in and is in a partially enrolled pose believed to be a behavior of trilobites when subjected to death or danger, similar to modern Pill bugs. Both eyes are complete with full lens detail and top preservation. Excellent pustulose detail throughout. This example features the finest preservation and detail. Entire trilobite is well-preserved with very full inflation and no damage or distortion.
