On the edge of the Brecon Beacons, Upper Gilwern Hill is a site long known for its well-preserved and complete trilobites. The hill is made up of rocks from the Lower and Middle Ordovician, and the privately owned quarry is accessible to parties staying at the onsite Shepherd’s Hut self catering accommodation. The trilobite fossils here are plentiful and the chances of finding a good number is very high.

Many fossils can be found on the scree surface, but the use of a geological hammer and a bolster chisel to split the shale along the bedding plane will reveal many and often complete specimens. Safety goggles are essential. The sheer number of trilobite fossils indicates a rapid burial and death, probably from hot, burning ash raining down from sub-aerial volcanoes, followed by poisoning from noxious fumes.

The fauna here is dominated by the large asaphid trilobite, Ogyginus cordensis. Other common trilobites are the trinucleidsBettonolithus chamberlaini and Trinucleus abruptus, as well as the rarer, Anebolithus simplicior. Other fossils include orthocones, sponges, brachiopods and graptolites
