RARE Beltella depressa Trilobite Fossil

Upper Cambrian – Pont Abergeirw, Afon Mawddach Valley, North Wales, UK

This listing offers a rare opportunity to own a scientifically significant
trilobite fossil of the species Beltella depressa, discovered at Pont Abergeirw near the Afon Mawddach river in North Wales. This fossil comes from Upper Cambrian strata and represents a less commonly encountered genus within the Olenidae family.

Geological & Palaeontological Details:


• Fossil Type: Articulated trilobite impression or partial fossil
• Species: Beltella depressa
• Locality: Pont Abergeirw, Afon Mawddach, Wales, UK
• Geological Stage: Upper Cambrian (Furongian)
• Formation: Likely part of the Mawddach Group of North Wales
• Depositional Environment:
• Marine basinal mudstones
• Likely deposited under low-oxygen (dysoxic) conditions favourable to Olenid trilobite preservation
• Family: Olenidae
• Superfamily: Olenoidea
• Order: Ptychopariida
• First Described By: Beltella was established by Howell in 1935
• Zone/Biozone: No formally assigned trilobite zone for this exact species, but consistent with Olenid biofacies in upper Cambrian of Wales

Morphology Features:


• Beltella depressa typically exhibits:
• A low-profile cephalon with reduced glabellar inflation
• Elongated thoracic segments
• Smooth, streamlined pygidium
• Delicate exoskeletal features often preserved as impressions in fine-grained matrix
• Morphology suggests an adaptation to soft-bottom, low-oxygen seafloor environments

Scientific and Collectible Value:


• This is a less frequently encountered genus in Welsh Cambrian trilobite faunas
• Important for understanding regional biodiversity and trilobite adaptation to dysoxic depositional settings
• Rare fossil from a restricted locality in the Mawddach Basin
• Excellent specimen for educational, comparative, and collection purposes
