Ceratarges Couche
Middle Devonian Period

The 3rd locality of Day 2 was a Devonian couche, named for a spiny trilobite.
Its up this hill somewhere. Its Silurian at the base, then transitions to Devonian and gets younger as you go further.

The previous excavations mark the spot.

A line of dig holes follow the productive layer.

To get the freshest material, one has to dig a cavity into the layer and extract large chucks of rock.

Having no heavy equipment, we opted to look through the tailings, splitting them further in hopes of finding some that had been missed.

This is what they look like when you split the rock and find something.

The strategy was reasonably effective as we found about 10 potential pieces and several practice pieces.
