From the portion of the Glyndwr’s Way walk that passes through the woods on Gallt yr Ancr hill, west of Meifod, fossiliferous sandstone blocks can be collected. These, when split, can yield excellent brachiopod fossils.


♦ Parking can be found in a small layby next to the start of the walk into the woods at Gallt yr Ancr hill.
♦ Walk into the woods and after perhaps a hundred metres you will come to a gate.
♦ The hillside to your left as you come to this gate has many sandstone blocks scattered over it.
♦ Just past the gate there is a side path that climbs into the woods. Blocks can be found close to this path also.
♦ Ref: 52.70895°N, 3.26565°W


FIND FREQUENCY: ♦♦♦ – The right sort of blocks yield many good quality fossils; these blocks are fairly abundant but can be difficult to find.
CHILDREN: ♦♦♦ – It is a short walk into the woods over easy terrain. Children should have no problems with this location.
ACCESS: ♦♦♦♦♦ – The hill is very close to Meifod and the path into the woods is short and easy.
TYPE: – Fossils are found in sandstone blocks which litter the hillside. These blocks are largely derived from old quarries.


Many sandstone blocks have evidence of seams of brachiopods within them. These are shown by hollow brachiopod sections in the sides of the rock. When split open, these will often yield brachiopod assemblages on the bedding planes. Small trilobite pieces can also be found among the brachiopods.

You should look for these blocks at the sides of the side path as it rises into the woods after the gate, approximately 100m into the wood. There are also blocks to be found a few metres off of the path just before the gate.

Brachiopod mould


The Ordovician Sandstone at Meifod is around 450million years old. It is of Caradoc age and part of the Ogwen Group. The sandstone is from the Nod Glas Formation.

As this is a remote location it is best to visit in pairs or as a group. A mobile phone should be taken and someone should be told where you are going and when you expect to be back.


As this is a peaceful setting alongside a tranquil path it is best to take blocks home to split them there. In this case, just a sturdy bag and some packing material is required. When home, the blocks can be split using a geological or lump hammer.


There is a public footpath into the woods, stone blocks can be collected within a few metres of the path.
