Description
U-shaped burrow with spreite; vertical to bedding plane; limbs of U parallel; both limbs of each successive U-tube confluent with limbs of preceding U-tube (see KNOX, 1973, p. 134); openings of tubes mosdy funnel-shaped (but apparendy often truncated by erosion); commonly protrusive, but also retrusive forms observed; bottom of burrow semicircular, rarely straight; horizontal cross section on bedding planes dumbbell-shaped; diameter of tubes 5 to 15 mm., distance between limbs I to 7 em. (average, 2-3 em.), depth of burrows 2 to 15 em. (max. 35). [Dwelling burrow of suspension feeding animal, probably living in environment of high wave energy; several stages of erosion and sedimentation may be recognized from various levels of tube (e.g., D. yoyo; see GOLDRING, 1962, p. 235, and Fig. 16); intermediate forms between Diploeraterion and Rhizocorallium observed in the Carboniferous of Scotland (CHISHOLM, 1970b, p. 49).]
