Schematic depiction of a bird facing right and downwards, which measures 14.5 cminlength,7 cmin width, andamaximum between parallels of11.5 cm. It has a negative inclination of 6° east and its orientation is 60° north. This figure is particularly difficult to describe since it is impossible to associate it with any image known to us, or it is depicted in such a way that it cannot be interpreted correctly. Its upper part starts with a sinuous line, convex at first and then concave, the latter being what we think represents the globular head. Inside it there is an elliptical groove which doubtless is intended to depict the eye, and from here there extends the convergent line that forms this bird's broad beak. At left, in some places the line is superimposed on, or is parallel to the bird's bill described above. Another discontinuous incision, at first convex and then concave, ends the depiction. As we have said, it is complicated to classify this representation taxonomically, but there is no doubt that with such a broad beak it must be a grulliform or a coniform. The groove is V-shaped in section, relatively wide (<3 mm) and deep (<3 mm) and is totally patinated.
