Guizhoudella dinodontoides Dzik, 2006 from the L. styriacus Zone at Miedzianka, Jabłonna and Kowala in the Holy Cross Mountains.

Apparatus composition of Guizhoudella dinodontoides.

Diagnoza

Relatively small basal cone and wide, flat denticles; processes of ramiform elements with a low platform forming a ribbon-like structure along their basal parts.

Porównanie

Similar to the type species, the new species is also long ranging and extremely variable, but species distinction is rather certain. Only juveniles lacking characteristic denticulation and ribbon-like platform may be misidentified. Much less certain is identification and homology of particular element types. Two elements from Miedzianka may represent the platform series  if they truly belong to the species (they lack the tuberculation occurring in undoubted specimens). Alternatively, the platform series is represented by elements with relatively straight processes but otherwise similar to other element types. The elements S₀ and S₁ may or may not have the medial process, but it seems to be always rather short in length, unlike the probably homeomorphic Carboniferous Dinodus.
