Here we have a interesting  specimen of a pathological brittle star fossil of the species Ophiurina lymani.
The brittle star exhibits bite marks, which were likely fatal, as more than half of the central disc is missing. Even the remarkable regenerative abilities of the Ophiuroidea clearly have their limits.

This is a small but detailed regular sea urchin which belongs to the genus Phymosoma. 
This fossil echinoid from Painten snows many spines.
These spine  have a longitudinal striated ornamentation

Here we have a very detailed preserved caproid  of the species Rhenocystis latipendunculata from the Lower Devonian of Bundenbach.

Here is a cropolite of the species Lumbricaria intestinum together with a fossil Crinoid of the species Saccocoma tenella.

Here is a solutan carpoid echinoderm from the Fezouata Shale of Morocco. The carpoid shows some affinitiy some to Plasiacystis mobilis but it is likely a not described species.

Here is a rarely offered plate with several fossil brittle stars of the quite rare species Stephanura belgica from the upper Devonian by Velbert near Langenholz in Germany.
 

This is a Cystoid of the species Cystoid Sucocystis theronensis from the middle Cambrian of France.
 

Here is a fossil Solnhofen echinoid from the Painten Site. The fossil Tetragramma is completely preserved with the spines and the Aristotle's lanten.

This is a fossil starfish of the species Urasterella asperula from the Devonian of Bundenbach.
