Catalogue entry no. 182 by Max Loehr:
182 Trapezoidal Plaque with Zoomorphic Ornament
Mottled greenish and light brown jade, with red stains on one side. Along the irregular top and back edges, which like the concave lower edge are recessed, there are incised transverse scores. The front edge, by contrast, is adapted to the profile of an animal head that appears identically on both sides. Adjoining the face, a set of three angular spirals with a claw beneath them extends to the back; a broad, finely grooved band rises above the horn and in consecutive angles swept back, down, upward, and back again, forming a large meander which adds both a contrasting texture and a unifying strength to the design as a whole. A small biconical hole cuts into the lower margin of the relieved design. Shang.
The curvature of the lower projection suggests that this piece was carved from a disk fragment, and the very irregular shape of the edges seems to support this assumption.
