RARE Enrolled Brongniartella minor Trilobite Fossil

Caradoc Stage, Ordovician Period – Coed Maes Newyddion, Eryri (Snowdonia), Wales

An exceptional and rare example of an enrolled trilobite fossil from the Caradoc-aged rocks of Coed Maes Newyddion in the Eryri (Snowdonia) region of North Wales. This specimen is identified as Brongniartella minor, a distinctive trilobite from the Middle to Late Ordovician and notable for its compact, tightly enrolled preservation.

This well-preserved fossil captures the ancient defensive posture of trilobites, coiled into a ball to protect their soft undersides—making this a prized example of behavioral fossil evidence.

Geological & Stratigraphic Information:

  • Formation/Locality: Coed Maes Newyddion, Eryri (Snowdonia), Wales
  • Geological Stage: Caradoc (Middle to Upper Ordovician, ~460–450 million years ago)
  • Depositional Environment:
  • Marine shelf environment
  • Fine siltstones and mudstones, likely deposited under relatively low-energy conditions
  • Fauna-rich marine strata supporting trilobites, brachiopods, and graptolites
  • Biozone (if inferred): Likely in the Nemagraptus gracilis Biozone or equivalent, typical of Caradoc faunas
  • Preservation: Calcareous or siliciclastic shale preservation, fossil shows natural articulation

Taxonomic Details:

  • Kingdom: Animalia
  • Phylum: Arthropoda
  • Class: Trilobita
  • Order: Phacopida
  • Family: Encrinuridae
  • Genus: Brongniartella
  • Species: Brongniartella minor
  • Described by: Reed, 1896

Morphological Features:

  • Compact, enrolled specimen—head (cephalon) and tail (pygidium) tightly joined
  • Moderate cephalic spines and well-developed axial lobe
  • Crescentic eyes visible under magnification
  • Exoskeleton shows detailed segmentation and pleural lobes

Scientific & Collector’s Value:

  • Excellent example of enrolment in trilobites—an important behavioural adaptation
  • Rarely found in such complete and naturally enrolled state
  • Important representative of Ordovician faunal assemblages in the UK
  • Desirable for both scientific reference and high-end fossil collections

Specimen Details:

  • Fossil Type: Enrolled trilobite
  • Species: Brongniartella minor
  • Origin: Coed Maes Newyddion, Eryri (Snowdonia), North Wales
  • Authenticity: 100% Genuine Specimen

Ordovician Information

The Ordovician Period (485–443 million years ago) was a time of marine expansion and biodiversity growth, following the Cambrian Explosion. Warm, shallow seas covered much of the continents, supporting trilobites, brachiopods, corals, and the first true reefs. Jawless fish (early vertebrates) diversified, and the first sea scorpions (eurypterids) became dominant predators. On land, the first primitive plants (moss-like bryophytes) began colonizing damp environments. The climate was initially warm, but by the late Ordovician, a major ice age caused a drastic drop in sea levels, triggering the Ordovician-Silurian mass extinction, which wiped out nearly 85% of marine species. Despite this, the period laid the foundation for the rise of more complex ecosystems in the Silurian.
