Salterella is an enigmatic Cambrian genus with a small, conical, calcareous shell that appears to be septate,[3] but is rather filled with stratified laminar deposits.

[5] The genus was established by Elkanah Billings in 1861, and was named after the English palaeontologist John William Salter.

[1] The genus is known from multiple locations worldwide, such as Newfoundland and Labrador and Quebec in Canada,[6][7] Svalbard,[8] the Scottish Highlands[9] and Argentina.

[10] 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).

[9] However, Volborthella was later accepted as a separate genus again by Yochelson & Kisselev in 2003.
