Diagnosis: Discrete oval chambers embedded in bone with walls perpendicular to the bone surface; the base is flat and runs parallel to the bone surface. The contact between the base and the walls is predominantly sharp but occasionally slightly rounded. The length of these traces roughly doubles their maximum width. These are found isolated or in clusters of two or four borings, rarely intersecting each other, and most often in different orientations relative to one another (Serrano-Branas ˜ et al., 2018)

Diagnosis: Discrete oval borings embedded in bone with straight walls running perpendicular to the bone surface. Bottoms are flat and run parallel to the bone surface (Figs. 2B, 4B, 4C). The contact between the walls and the bottom are predominately sharp but may be slightly rounded. The length is roughly double the maximum width. The trace either occurs individually (Fig. 4C) or in clusters (Fig. 4B) of two to four borings. In clusters traces infrequently intersect (Fig. 4B) but in general show no consistent orientation to one another.
