Ogygiocarella angustissima Trilobite

Travel back approximately 458 million years to the Late Ordovician with this impressive Ogygiocarella angustissima trilobite fossil from the Llanfawr Mudstone Formation near Llandrindod Wells, Wales. This distinctive specimen offers a fascinating glimpse into the ancient marine environments that once covered parts of present-day Britain.

Measuring approximately 2 inches, this trilobite features an elongated, oval-shaped body with a rounded head, numerous finely defined thoracic segments, and a broad, rounded tail section. Its detailed segmentation and prominent central axis remain visible against the dark gray mudstone, revealing the intricate anatomy of this prehistoric marine arthropod.

The fossil is preserved on an approximately 5 x 2.25-inch natural matrix with irregular edges, subtle color variations, and visible fractures/repair extending across portions of the stone and fossil. The dark, fine-grained matrix creates an attractive, understated presentation that highlights the trilobite's distinctive features.

Ogygiocarella angustissima is an asaphid trilobite known from the Ordovician rocks of Wales. Like other trilobites, it possessed a segmented exoskeleton that provided protection while allowing flexibility and movement along the ancient seafloor. Fossils from the Llanfawr Mudstone Formation offer valuable insight into the diverse marine ecosystems that existed hundreds of millions of years ago.

With its elongated form, finely preserved segmentation, and natural dark mudstone matrix, this specimen makes an interesting addition to any fossil collection or natural history display.
