RARE Parabolina spinulosa Fossil Trilobite

Upper Cambrian – Dolgella Series – P. spinulosa Zone – Foel Gron, Meirionnydd,
Wales.

This listing features an authentic and exceptionally rare fossil specimen of the trilobite Parabolina spinulosa, originating from the world-renowned Upper Cambrian strata at Foel Gron, Meirionnydd, North Wales. Collected from the Dolgella Series, specifically the P. spinulosa Zone, this fossil is both scientifically important and a beautiful collector's piece.

Geological and Stratigraphic Details:

• Formation: Dolgella Series
• Zone: Parabolina spinulosa Biozone
• Location: Foel Gron, near Trawsfynydd, Meirionnydd, Wales
• Geological Period: Upper Cambrian (~497 to 485 million years ago)
• Depositional Environment:
• Outer shelf marine basin
• Deep-water, anoxic, fine-grained mudstone facies
• Low-energy, sediment-rich paleoenvironment
• Stratigraphic Significance: This zone is used for high-resolution biostratigraphic correlation within the Cambrian, across parts of Wales and Scandinavia.

Taxonomy:

• Kingdom: Animalia
• Phylum: Arthropoda
• Class: Trilobita
• Order: Ptychopariida
• Superfamily: Olenoidea
• Family: Olenidae
• Genus: Parabolina
• Species: spinulosa
• Described by: (Angelin, 1854)

Morphological Features:

• Elongated and narrow body profile
• Distinctive spinose features on the pygidium (tail)
• Fused facial sutures and well-defined glabella
• The trilobite is often preserved in full dorsal profile or as detailed impressions, depending on preservation conditions
• Often found as moults (exuviae), indicating high fossil abundance and biological turnover in the zone

Why This Fossil Is Notable:

• Parabolina spinulosa is the index fossil for its biozone, making it vital for stratigraphic correlation
• Commonly used in academic and geological research as a marker species for the Upper Cambrian
• Specimens from Foel Gron are prized for their preservation quality and scientific relevance
• Excellent educational and display specimen from a historically important trilobite site in Britain
