Ellisell
''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 (1928–2006), who had turned 60 at the time the fossils were first described. The genus was originally placed in the family Salterellidae of the phylum Agmata; this placement was rejected by Yochelson & Kisselev (2003), but was restored by Peel (2016). ''Ellisell'' is distinguished from ''Salterella ''Salterella'' is an enigmatic Cambrian genus with a small, conical, calcareous shell that appears to be septate, but is rather filled with stratified laminar deposits. The shell contains grains of sediment, which are obtained selectively (with a ...'' 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.

Salterellidae
Salterellidae is a family of enigmatic fossil genera from the Early to Middle Cambrian. It was originally created for the genus ''Salterella'' by Charles Doolittle Walcott, who placed it in the group Pteropoda. It was later placed in Agmata, a proposed extinct phylum by Ellis L. Yochelson which is accepted by some other authors.

Agmata
Agmata is a proposed extinct phylum of small animals with a calcareous conical shell. They were originally thought to be cephalopods or annelid worms. The living animals filled up to five-sixths of their shell with laminae, angled layers composed of grains of quartz or calcium carbonate detritus from the environment cemented together, with larger grains near the shell wall and smaller grains near the center. A very fine tube ran through the center of the shell. The grains may be of quartz or calcium carbonate, but are of specific shapes and materials that are rare in the surrounding rock. Though the body of the living animal is not preserved, it had to be able to find, choose, and retrieve rare grains from its environment to build the laminae. The phylum's name comes from the Greek word for "fragments", referring to these fine fragments and grains of detritus. It was proposed by the paleontologist and geologist (1928–2006) in 1977 to house the agglutinating Early Cambrian fossi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Salterella
''Salterella'' is an enigmatic Cambrian genus with a small, conical, calcareous shell that appears to be septate, but is rather filled with stratified laminar deposits. The shell contains grains of sediment, which are obtained selectively (with a preference for denser grains) by a manner also observed in foramanifera. The genus was established by Elkanah Billings in 1861, and was named after the English palaeontologist John William Salter. The genus is known from multiple locations worldwide, such as Newfoundland and Labrador and Quebec in Canada, Svalbard, the Scottish Highlands and Argentina. The related fossil genus ''Volborthella'' was formerly placed in synonymy with ''Salterella'' by Ellis L. Yochelson in 1983, due to the similarities between the two genera (though ''Volborthella'' notably lacks an outer calcareous shell). However, ''Volborthella'' was later accepted as a separate genus again by Yochelson & Kisselev in 2003. Both genera are currently placed in the Salterell ...
