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
| Reference | Diagnosis | |
|---|---|---|
| W. Hantzschel 1975 | “Trumpet pipes”; funnel structure penetrated by central straight or slightly curved plugged tube, perpendicular to bedding plane, never branched; diameter commonly 5 mm, up to 8 cm (max 16) long; funnel simple or multiple (latter discernible in transverse section as a series of concentric rings); diameter of funnels usually 1 to 4 cm, greatest depth about 2 cm; tubes commonly abundant but never crowded like Skolithos. Funnel obviously constructed by upward migration of animal inhabiting tube is reflected by downward warping of surrounding bedding planes toward central tube. |
