Surusicaris is an extinct genus of bivalved arthropod, known from the Cambrian Burgess Shale of British Columbia, Canada.

It is considered to be closely related to Isoxys, and like it has spined grasping frontal appendages.

The head also has three pairs of other limbs, which are stubby, uniramous and unsclerotised, with an annulated appearance, which are tipped with bifid claws.

Their morphology is simple, the morphology of the endopod is similar to those of the anterior three uniramous head limbs, while the exopod is sub-lobate, elongate, and possibly flattened, with marginal setae and about the same length as the endopod.

The posterior is poorly preserved, but may be a tail-piece formed by two lobes or a fan.
