Gogia spiralis, (1:1) 8 cm.
The model was made in oversize and shrunk to achieve a high degree of details.
Supervised by Günter Bechly.
This animal is an extinct member of the echinoderms - this is where sea stars and sea urchins belong. The group that Gogia wa a part of is called blastozoans. It is distinguished from sea lilies, and most other blastoids, in that the plate-covered body was shaped like a vase, or a bowling pin (with the pin part stuck into the substrate), and that the five ambulacra were split into pairs of coiled or straight, ribbon-like strands. Six specimens of Gogia are known from the Greater Phyllopod bed, where they comprise < 0.1% of the community.
As a whole, the Eocrinoids are regarded as basal blastozoans very close to the ancestry of the entire subphylum.
