Editorial summary

The public source identifies “Yonenga worm snake” as species of reptile. This brief keeps that definition visible, then builds a research path around Yonenga, worm and snake.

Editorial reviewA sound reference starting point where classification, measurement and the date of the underlying evidence remain visible. The current 134-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Yonenga, worm and snake providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Yonenga worm snake”, the useful work is to connect “species of reptile” to the records capable of establishing context and consequence.

Evidence profile

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 May 19, 2026. The linked authority identifier is Q3010348. None of the 0 selected statements returned an explicit reference.

Critical limits

A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. 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.
