Description
Asaphid Pygidium Fossil Trilobite
This fossil is identified as an asaphid pygidium, the preserved posterior section of a trilobite, and is associated with the Ordovician of Sweden. Its scientific identification and geological age make it an appealing addition to collections focused on trilobites, Ordovician fossils, palaeontology and the history of ancient marine life.
Identification and Geological Context
Trilobites were extinct marine arthropods that lived during the Palaeozoic Era. Their bodies were divided into three longitudinal lobes, a feature reflected in the name “trilobite”, and were protected by a segmented exoskeleton. The pygidium is the rear portion of that exoskeleton. In many trilobites, the pygidium preserves important structural features such as segmentation and the overall shape of the posterior shield, making it a particularly recognisable and scientifically interesting part of a trilobite fossil.
The specimen is identified specifically as an asaphid pygidium. Asaphid trilobites are associated with the diverse trilobite faunas of the Ordovician Period, a significant interval in the development of marine ecosystems. This fossil therefore offers a tangible connection to Ordovician palaeontology and the ancient marine environments represented by fossil discoveries from Sweden.
Collection History and Display Appeal
This specimen is from the Alice Purnell Collection, giving it a documented collection association for collectors who value the background and history of individual fossil pieces. Its compact pygidium form makes the fossil suitable for a trilobite collection, geological display, educational setting or palaeontology-themed interior. It can also serve as a useful study example when examining the distinctive posterior anatomy of trilobites and the way fossilised exoskeletal elements preserve evidence of extinct organisms.
The supplied identification, Ordovician age and Swedish association are central features of this fossil. No additional formation, zone or species-level identification is stated, allowing the piece to be appreciated accurately without attributing unsupported details. The fossil is offered as the actual specimen shown in the listing photographs.
