Diagnoza

The elements P₁ are generally robust but highly variable, some having prominent high ribs at the occlusal surface that look almost like denticles, others have a relatively thin platform ornamented with rather low sharp ribs.  

Porównanie

Juvenile specimens develop a platform much above the base but still below the main row of denticles, which makes them distinct from the co-occurring Pseudopolygnathus primus which still preserves an ancestral icrion-like arrangement of denticles, with only an incipient plafform.
