Giroskoobids are a proposed order of small marine invertebrates known primarily from fossil microfossils and occasional soft-tissue impressions. The name giroskoobid combines a reference to circular or spiral motion with a conventional taxonomic suffix used in speculative meiofaunal groups. The group was introduced to classify a set of minute, circularly shielded shells that recur across several fossil assemblages, though their exact relationships remain debated.
