Ancyrodella lobata Branson & Mehl, 1934 from the lower cephalopod limestone of the late Frasnian of Płucki.

Diagnoza

A very few ramiform elements have been identified in sample Wł-R/C1 as possibly belonging to this species which is characterised by a wide and frequently bifurcating rostral lobe. Sample Pł-22 from the lower cephalopod limestone at Płucki yielded unnumerous robust ramiform elements which may belong to the species but they show a very wide variability and the differences from associated polygnathids are not clear.
