Taxonomy

"Ca. Lokiarchaeum" was described in 2015 and was assigned to the phylum "Lokiarchaeota". In 2017, "Lokiarchaeota" was assigned to the superphylum "Asgard", as well as other phyla. Later, the superphylum "Asgard" was de-ranked to the phylum "Asgardarchaeota". In 2023, the species "Ca. Lokiarchaeum ossiferum" was described.

Editorial summary

The public source identifies “Lokiarchaeum” as candidate genus of archaea. This brief keeps that definition visible, then builds a research path around Lokiarchaeum, candidate and genus.

Editorial reviewA sound reference starting point where classification, measurement and the date of the underlying evidence remain visible. The current lead gives the account dated anchors—2015, 2017, 2023—that can be checked directly. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Lokiarchaeum, candidate and genus providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Lokiarchaeum”, the useful work is to connect “candidate genus of archaea” to the records capable of establishing context and consequence.

Evidence profile

Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Jun 22, 2026. The linked authority identifier is Q134837761. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2015, 2017 and 2023.

Critical limits

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
