Oldhamia curvata Lindholm et Casey, 1990

Emended Diagnosis: Oldhamiawith thin, uniformlycurved, unbranched probings, commonly forming al-most symmetrical fan structures and leaving a gap inthe center. Probings commonly regularly spaced, maintaining the curvature along their trajectory.Asymmetric forms rare.

Diagnosis. Thin, curved, unbranching, unlined burrows that form two opposing fan-shaped traces. Both fans generally of similar size and geometry but not necessarily identical in number of burrows or amount of curvature. All burrows converge at either a central area (Fig. 8D) or connect to a common burrow (Figs. 8F, 8G)
