Brasilennea

Brasilennea is a fossil genus of small to medium-sized air-breathing land snails, terrestrial pulmonate gastropods in the family Cerionidae. The genus is known only from the Brazilian Paleocene Itaboraí Basin, in Rio de Janeiro.[3] The most characteristic feature of the genus is its two spiral furrows on the body whorl.[3]

The generic name Brasilennea originally intended to imply that it is a Brazilian genus that is very similar and related to the African genus Ennea.[2] This is no longer the case, however: while the genus was originally classified in the family Streptaxidae,[2] Brasilennea was then later transferred to the family Cerionidae.[3]

Species

Species within the genus Brasilennea include:

gollark: AyScorch, and yes I did.
gollark: I have no idea *why* I was trusted (I'm sure some chatlogs aeons ago show it) but I clearly *was*, even though I was later untrusted.
gollark: YOU had no authority to demand I leave a claim I was equally permitted to be in.
gollark: I did so, after he got on.
gollark: Sounds like harassment!
