Three Recumbent Animals on a Plaque

Three quadrupeds rest on top of a more or less rectangular plaque. The animals are virtually identical. They are alert, with the head raised and pointing forwards; the legs are bent and extend to the edges of the plaque. The animals have flat and broad tails, somewhat pointed muzzles, ears extending sidewards, and short horns or antlers. Due to the corrosion, it is difficult to determine their species with certainty, but they resemble deer, or perhaps goats. The underside of the plaque is uneven; at its center is a tang of roughly square section. Green patina over red; with a spot of turquoise underneath.
