Why this record matters
A short description can identify a subject without explaining its stakes. For “Furtive tuco-tuco”, the useful work is to connect “species of mammal” to the records capable of establishing context and consequence.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Sep 28, 2025. The linked authority identifier is Q1764947. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2005, 1538 and 1600.
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.
