'''''Repinaella''''' is an [extinct](/source/extinct) [genus](/source/genus) from a well-known class of [fossil](/source/fossil) marine [arthropod](/source/arthropod)s, the [trilobite](/source/trilobite)s. It lived during the late [Atdabanian](/source/Atdabanian) stage.

== Distribution ==
* ''Repinaella siberica'' has been found in the Lower Cambrian of Siberia (Pestrotsvet Formation, Lena River).<ref name="Hollingsworth">{{cite journal|last=Hollingsworth|first=J.S.|year=2005|title=The earliest occurrence of trilobites and brachiopods in the Cambrian of Laurentia|journal=Palaeogeography, Palaeoclimatology, Palaeoecology|volume=220|issue=1–2|pages=153–165|url=http://ysgeo.yonsei.ac.kr/abstractII/E0422001009.html|doi=10.1016/j.palaeo.2004.08.008|bibcode=2005PPP...220..153S|url-status=dead|archive-url=https://web.archive.org/web/20140606221919/http://ysgeo.yonsei.ac.kr/abstractII/E0422001009.html|archive-date=2014-06-06|url-access=subscription}}</ref>
* cf. ''Repinaella sp.'', the first trilobite to appear in [Laurentia](/source/Laurentia), has been reported from the Lower Cambrian of Nevada (Northern Clayton Ridge; Andrew Mountain Member of the Montezuma Range, Campito Formation). The occurrence of cf. ''Repinaella'' is approximately correlative with the earliest trilobites in Siberia and western Gondwana.<ref name="Hollingsworth"/>

== Taxonomy ==
Within the "Fallotaspidoidea" superfamily ''Repinaella siberia'' is closest to the common ancestor with the other Olenellina, particularly ''[Pseudojudomia egregia](/source/Pseudojudomia_egregia)'', and the common characters of these two species were probably shared with the common ancestor of all trilobites.<ref name="Lieberman 2002">{{cite book|last= Lieberman|first= B.S.|title= Phylogenetic analysis of some basal early Cambrian Trilobites, the biogeographic origins of the Eutrilobites, and the timing of the Cambrian radiation|year= 2002|journal= Journal of Paleontology|volume= 76|number= 4|pages= 692–708|url= https://books.google.com/books?id=KykRuQwrVuUC&pg=PA153 |doi=10.1666/0022-3360(2002)076<0692:paosbe>2.0.co;2|isbn= 9780444520654}}</ref>
