Differential weathering of the less resistant burrow- fill and lining results in a bedding surface crowded with holes perpendicular to bedding. Scale = 5 cm. Interpretation These vertical burrows are broadly similar to Ophiomorpha but lack the typical dichotomous branching of that ichnogenus. If the openings were more distinctly funnel-shaped and the plugged tubes curved in vertical section, Mono- craterion might
