Opis

Diagnosis. — The P1 elements with more or less reduced dorsal process, otherwise the apparatus with a generalized polygnathid-like structure; the prioniodinid affinities disclosed only by the ‘enantiognathus’ appearance of S1 elements.
Remarks. — The oldest undoubted gondolellid Gondolella are known from the late Carboniferous (von Bitter and Merrill 1998). Its apparatus differs from that of Branmehla only in the morphology of element lacking dorsal process but bearing a platform along the ventral process. Juvenile elements of Branmehla closely resemble the paedomorphic Permian and Triassic gondolellid Neospathodus.
