This elegant specimen of Asaphus lepidurus, partially enrolled in its characteristic defensive posture, offers a striking glimpse into the survival strategies of trilobites during the Paleozoic era. Originating from the Ordovician period, this fossil preserves the fine details of the exoskeleton, with the distinct segmentation and gently curved form still clearly visible. Partial enrollment was a protective response, allowing the trilobite to shield its softer underside — and in this specimen, that behavior has been frozen in time for over 450 million years. A beautiful balance of form and function, this Asaphus represents both the artistry of nature and the resilience of ancient marine life. Trilobite is 3,5 cm
