Source-derived summary

Exafroplacentalia or Notolegia is a clade of placental mammals proposed in 2001 on the basis of molecular research.

Exafroplacentalia places Xenarthra as a sister group to the Boreoeutheria (comprising Laurasiatheria and Euarchontoglires), thus making Afrotheria a primitive group of placental mammals (the group name roughly means "those which are not African placentals").

Classification

However, this classification makes the autapomorphy (character shared only among Exafroplacentalia) dubious: it is hard to classify a group by the absence of a feature (in this case "not coming from Africa"). Hence, several alternative hypotheses can be considered.

Editorial summary

Begin with the source’s own compact description: “Exafroplacentalia” is clade of placental mammals. The dossier treats that line as a proposition to test through Exafroplacentalia, Clade and placental, not as a finished interpretation.

Editorial reviewA concise reference frame for defining the subject, testing terminology and identifying the institution closest to the evidence. The current lead gives the account dated anchors—2001—that can be checked directly. The selected authority fields contribute no independent date. For this dossier, Exafroplacentalia, Clade and placental is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “clade of placental mammals” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Apr 13, 2025. The linked authority identifier is Q133342. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2001.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
