In the 1990s, excavations uncovered the remains of a small Neolithic settlement at Stonehall, at the foot of Cuween Hill, and in 2019 images of a forensic model of one of the dog skulls were published.

Scientists at Edinburgh University's Royal (Dick) School of Veterinary Studies CT-scanned one of the canine skulls, enabling forensic artist Amy Thornton to make a model of the dog's head based on a 3D print of it.
