* The fossil plant ''[[Paradinandra|Paradinandra suecica]]'' could not be assigned to any family, but was placed ''incertae sedis'' within the order [[Ericales]] when described in 2001.<ref>{{cite journal |author1=Jürg Schönenberger |author2=Else Marie Friis |author-link2=Else Marie Friis |date=March 2001 |title=Fossil flowers of ericalean affinity from the Late Cretaceous of Southern Sweden |journal=[[American Journal of Botany]] |volume=88 |issue=3 |pages=467–480 | pmid = 11250825 |doi=10.2307/2657112|jstor=2657112 |bibcode=2001AmJB...88..467S }}</ref>
* The fossil ''[[Gluteus minimus (fossil)|Gluteus minimus]]'', described in 1975, could not be assigned to any known animal [[phylum]].<ref name="Davis">{{cite journal |author1=Richard Arnold Davis |author2=Holmes A.

* [[Bocage's longbill]], ''Motacilla bocagii'', previously known as ''Amaurocichla bocagii'', is a species of [[passerine|passerine bird]] that belongs to the superfamily [[Passeroidea]]. Since it was unclear to which family it belongs, it was classified as Passeroidea ''incertae sedis'', until a 2015 phylogenetic study placed it in ''[[Motacilla]]'' of [[Motacillidae]].<ref>{{cite journal|author=Per Alström |author2=Knud A.

* ''[[Parakaryon myojinensis]]'', a single-celled organism that is apparently distinct from [[Prokaryote|prokaryotes]] ''and'' [[Eukaryote|eukaryotes]], being the only identified species with a completely unknown position within the [[tree of life (biology)|tree of life]].<ref>{{cite journal | last1 = Yamaguchi | first1 = Masashi | display-authors = etal | title = Prokaryote or eukaryote?

* [[Biological dark matter]], genetic material produced from unidentified microorganisms that appears to match no known species. Like ''Parakaryon'', its producers' positions in the tree of life are completely unknown.

* [[Circothecidae]] are a family of [[Cambrian]] animals, sometimes attributed to the [[Hyolitha]], though some authors suggest (on the basis of no specified evidence) that they are definitely not.
* The [[Titanomis|frosted phoenix]] moth (''Titanomis sisyrota'') is so rare and so obscure it is unable to be placed in any family within the [[Lepidoptera]].
