Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| B. S. Kues et al. 2002 | The shell is discoid in shape, with a wide, shallow umbilicus lined with a thickened inductura. The only ornamentation is a row of conspicuous nodes on a raised spiral ridge immediately below the upper suture, numbering from 16 (small specimen) to a maximum of 22 on the body whorl. The observable shell features are all consistent with the characteristics of T. illinoisensis (e.g., Kues and Batten, 2001), but poor preservation precludes positive assignment to that species. |
