Paleoctenophora
''Paleoctenophora brasseli'' is a fossil of a marine species ctenophore,〔http://www.marinespecies.org/aphia.php?p=taxdetails&id=559324〕 found in Devonian slate near the German town of Buntenbach in Hunsrück, Germany, as a member of the Hunsrück Slate Lagerstätte.
==Paleobiology==
It is approximately 400 million years old. Compared to the other Hunsrück species, ''Archaeocydippida hunsrueckiana'', ''P. brasseli'' is poorly preserved. Portions of comb rows are preserved, but the number can not be determined: ''P. brasseli'' is assumed to have around 8 rows, based on comparison with the similar-looking modern sea gooseberry genus, ''Pleurobrachia'', from the North Sea. The specimen does show the statocyst, however.
Both specimens of ''A. hunsrueckiana'' and ''P. brasseli'' are too delicate to be prepared, and all information extracted from them have been done via radiography〔
