Pauloterminus is an extinct genus of bivalved arthropod known from Early Cambrian (about 520 to 516 million years ago) Sirius Passet locality of northern Greenland.

[1] The ovoid-shaped bivalved carapace encloses the head and the anterior (frontmost) section of the trunk.

The thorax was likely tube shaped, and had six segments, each associated with a pair of biramous (two-branched) limbs, which decrease in size posteriorly.

The limb endopods (the inner, leg-like branch) are thin and annulate, and approximately 1 millimetre (3⁄64 in) in width, while the exopods (outer limb branches) were lobe-shaped and bore setae (hair-like structures).

[1] In its original description, Pauloterminus was noted to be morphologically similar to Waptia and Chuandianella, both historically considered "waptiids", but it is unclear whether the group is monophyletic.
