Cheiracanthus murchisoni Agassiz

Reconstruction (after Traquair, 1895)

This small to medium sized acanthodian is very common in the Sandwick Fish Bed. Loose spines can be found in the sediments above the Sandwick Fish Bed. The spines are tiny and not deeply inserted into the body. They were slender fishes and eaten often by the bigger predators in the lake.
