If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.

Diagnosis
ReferenceDiagnosis
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.
