Diagnosis
Reference | Diagnosis | |
---|---|---|
W. Hantzschel 1975 | “Form genus” in widest possible sense; plantlike dendritic patterns of small cylindrical ramifying tunnel systems; individual tunnels neither crossing each other nor interpenetrating (perhaps only between tunnels of different systems); one or few main axes open to surface; branching tunnels trending downward across bedding and then (at least their distal portions) mostly lying parallel to bedding planes; may branch in regular or irregular patterns (highly variable); angle of branching may also be variable or constant, between 25 and 40o; branches may be arranged in pinnate or radial patterns or form compact groups; diameter of tunnels 0.5 to 5 mm, remaining constant within entire tunnel system; otherwise varying from large to small; some tunnels with transversely built-in ellipsoidal pills (their probably fecal origin doubted); preservation of fillings of tunnels controlled by stratinomic factors. |
