Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| C. B. Skovsted and J. S. Peel 2007 | Laterally compressed internalmoulds of helcionelloid molluscswith a strongly overhanging apex and a large, hemicircular protoconch recall Planutenia from the upper Lower Cambrian of eastern Germany and the probably related Stenotheca emeiensis Yu, 1987 from North China (Feng et al. 1994). Elicki (1994, 1996) described seven specimens of two coÅ|occurring species of Planutenia, P. flectata, and P. incli- nata, but the differences between these forms are very slight and are likely to be artefacts of variation or preservation. Parkhaev (in Gravestock et al. 2001) synonomised Planutenia with Anabarella Vostokova, 1962, but Planutenia differs from the similarly compressed Anabarella by its lower rate of whorl expansion and the larger protoconch. |
