Armilimax pauljamisoni from the Middle Cambrian, Spence Shale, Wellsville Mtns, Box Elder Co., Utah.

Armilimax pauljamisoni is the first shell-bearing animal of its kind from the Great Basin and extends the diversity of body plans in the Spence Shale Fossil-Lagerstätte.

The morphology of Armilimax is ambiguous; it bears a seemingly U-shaped gut and, at the opposite end of its body, a shell without an apex. It has been tentatively interpreted as resembling Halkieria, but it does not contain sclerites. It is the first of its kind in the Great Basin. Only one species is known: Armilimax pauljamisoni.

Also on the piece of shale are Acrothele subsidua and Micromitra modesta, which are two genus of brachiopods. Thee are also impressions of Rusophycus, an ichnogenus of trace fossil.
