RARE Parabolinella bucephalus Trilobite Fossil

Mawddach Group, Cambrian – North Wales, UK

This specimen is a genuine fossil of Parabolinella bucephalus, a rare and scientifically important trilobite species from the Cambrian period, specifically from the Mawddach Group of North Wales. This group represents part of the classic Lower Palaeozoic succession of the Welsh Basin and is internationally recognised for its rich fossil content and contribution to trilobite biostratigraphy.

Geological and Palaeontological Details:

  • Fossil Type: Trilobite (single specimen, may be complete or partial depending on specimen)
  • Species: Parabolinella bucephalus
  • Geological Group: Mawddach Group
  • Geological Period: Upper Cambrian
  • Stratigraphy: Typically within the Cwmhesgyn or Dolgellau Formations
  • Location: North Wales, UK
  • Depositional Environment:
  • Deep marine, outer shelf to slope settings
  • Fine-grained siliciclastic sediments, often dark mudstones or siltstones
  • Morphology Features:
  • Crescentic cephalon (headshield)
  • Narrow glabella with reduced or no frontal lobe
  • Long genal spines extending from the cephalon
  • Tail (pygidium) small and subtriangular
  • Notable:
  • P. bucephalus is an indicator species within Upper Cambrian biozones
  • Frequently found in mass mortality layers, possibly linked to low oxygen or storm events
  • Biozone: Often associated with the Parabolina spinulosa or P. bucephalus Zone depending on context
  • Family: Olenidae
  • Superfamily: Olenoidea
  • Order: Ptychopariida
  • Identified by: Originally described by Salter in 1864 under earlier taxonomic revisions; later assigned to the genus Parabolinella

Cambrian Information

The Cambrian Period (541–485 million years ago) was the first period of the Paleozoic Era, marking a dramatic explosion of life known as the Cambrian Explosion. During this time, complex multicellular organisms rapidly diversified, giving rise to the first arthropods, mollusks, echinoderms, and chordates—early ancestors of vertebrates. The climate was generally warm, with high sea levels covering much of the continents, creating vast shallow seas where life thrived. Iconic creatures such as Trilobites, Anomalocaris, and Opabinia dominated the oceans, while the first primitive reefs formed. The Cambrian set the stage for the evolution of modern animal groups and the complexity of marine ecosystems.
