Taeniolabidoidea is a group of extinct mammals known whose fossils can be found in North America and Asia.

[citation needed] Lambdopsalis even provides direct fossil evidence of mammalian fur in a fairly good state of preservation for a 60-million-year-old animal.

The group was initially established as a suborder, before being assigned the rank of a superfamily by McKenna and Bell in 1997.

Russell notes that the taeniolabidoids had ever-growing, self-sharpening incisors, much like modern rodents, and the premolars that are usually characteristic of multituberculates are sometimes lost in this family.

[10] Derived characteristics of the taxon (apomorphies) include: "snout short and wide with anterior part of zygomatic arches directed transversely, resulting in a square-like shape of the skull (shared with Kogaionidae); frontals small, pointed posteriorly, almost or completely excluded from the orbital rim".
