From Fensome et al., 2019:
Avellodinium hauteriviense Prössl, 1990, p.99–100, pl.1, figs.3,7,14–15 ex Prössl, 1992b, p.113. Holotype: Prössl, 1990, pl.1, figs.3,7. This name was not validly published in Prössl (1990, p.99–100), since that author did not specify the
lodgment of the holotype. Questionable assignment: Prössl (1990, p.99). Age: early–late Hauterivian.

Original description: [Prössl, 1990, p. 99-100]: (Translation: LPP)

Diagnosis:
Sphaerical to subsphaerical cyst with smooth periphragm. The gonal and intergonal processes are bi- to trifurcate.

Description:
The cyst is thin-walled without significant indication of paratabulation. Its identification is made more difficult by the high number of intergonal processes, which are not always connected by sutures.
The processes in the cingular region are usually better developed than the rest.
The archaeopyle results from the loss of the epicyst and is type tAtP.
