« backFOSSIL TRILOBITE
(negative impression)
465 million years old
Ordovician period
Builth Wells, Wales
A good example of a trilobite from Wales. It is from Ordovician rocks exposed in a quarry at Gilwern Hill, near Builth Wells in mid Wales.
Trilobites, an extinct class of marine animals, are the oldest of all the familiar fossils. They flourished in the seas during the Ordovician period, an early division of geological time.
This is a negative impression, but no less impressive. Collected in 1993. Presented in a lidded gift box.
Please note: Some photographs are taken using oblique lighting to make the fossil easier to see.
