Ogyginus corndensis Fossil Trilobite Ordovician Wales UK Upper Gilwern Quarry COA

£36.00

Available here is a striking specimen of Ogyginus corndensis, a classic Ordovician trilobite from the Llanvirn Series, collected by our experienced fossil hunting team, Alister and Alison, on 27 March 2024 at the well-known Upper Gilwern Quarry, Wales, UK.

Ogyginus corndensis is a well-known trilobite species notable for its large, smooth exoskeleton, wide cephalon, and crescentic glabella. It is a member of the:

  • Order: Asaphida
  • Superfamily: Asaphoidea
  • Family: Asaphidae
  • Geological Stage: Llanvirn (part of the Darriwilian Stage, Middle Ordovician, ~465 million years ago)
  • Depositional Environment: Deeper marine shelf with fine-grained sedimentation and low-energy conditions

This trilobite is highly sought after by collectors due to its broad shape and excellent preservation in dark Ordovician limestone. Its morphology, especially the broad glabella and semi-circular pygidium, makes it easily recognisable and significant for study or display.

The fossil has been expertly cleaned, prepped, and treated by Alison to reveal its intricate details. The image shows the actual specimen you will receive, and includes a 1cm scale cube to aid with full sizing—please refer to the photo for dimensions.

All of our fossils are 100% genuine specimens and come with a Certificate of Authenticity (COA) to ensure confidence in its origin and authenticity.

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.
