Description: | Specimen of a fossil trilobite, Niobe homfrayi Salter, collected from unspecified rocks of Early Ordovician, Late Tremadoc age from Penmorfa, Porthmadoc, Gwynned (Wales). Collected by E.J. Garwood.
Trilobites are very common fossils in Ordovician rocks. They grew in stages by moulting (shedding) their shells at regular intervals and growing a new one. This is why incomplete bits of the moulted shells of trilobites are much more commonly found than complete specimens. This specimen of Niobe is the moulted tail (pygidium) of the animal.
The specimen was found in Wales.
It is from the Ordovician period (495 - 443 million years ago) | Publisher: | Tyne & Wear Archives & Museums | Subjects: | Classification: Animalia E.J.
