Comments

Taxonomy from Fossilworks.org.

I originally identified the fish as Plesioperleidus yangtzensis. The identification was corrected by Prof. Guang-Hui Xu, Chinese Academy of Sciences. It is possibly an undescribed species.
'Dear Thomas,
The specimen Ch2209 has a pterygial formula of D25/P16, A22, C33/T~40, a relatively short and deep body with striated scales. It does not belong to Plesioperleidus yangtzensis (which has 51 lateral line scales). Instead, it resembles Teffichthys wui, but differs from the later mainly in striated scales, a slightly more posteriorly located dorsal fin, a few more lateral line scales. I think it might represent Teffichthys sp.'
