Ellisell

Not to be confused with Ellisella.

Ellisell is a Middle Cambrian genus of fossils from Denmark. It contains only one species, Ellisell yochelsoni. Both the genus and species are named after the paleontologist and geologist Ellis L. Yochelson [de] (1928–2006), who had turned 60 at the time the fossils were first described.^[1] The genus was originally placed in the family Salterellidae of the phylum Agmata;^[1] this placement was rejected by Yochelson & Kisselev (2003),^[2] but was restored by Peel (2016).^[3] Ellisell is distinguished from Salterella by its slowly expanding conch and the resulting cylindrical apertural cavity, compared to the latter's more rapidly expanding conch and cone-shaped apertural cavity.^[1]
