Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| Z. Zhang et al. 2015 | The shell valves are biconvex and equivalved, circular in outline. They are relatively large, with a maximum width at mid-valve, about 12.8 mm from the posterior margin. The maximum shell length is approximately 13.6 mm. The pseudointerareais not preserved, most likely due to the strong compression andflattening during preservation. It is apparent that there are some impressions delineated by reddish-grown tints of haematite, probably representing some remains of soft tissues. Just beyond the posteromedian margin of the shell, there is a rope-like structurewith annulations, interpreted as the pedicle (Fig. 4.1, 4.3). The number of annulations is estimated to be 8–10 in the preserved 2.3 mm long proximal pedicle (Fig. 4.3). The pedicle is thin and around 1.1 mm in width, approximately 8.6% of shell width. There is no evidence of a coelomic canal in the preserved pedicle. |
