“Phrontis (gastropod)” enters the record as genus of Gastropoda. Crown Archives preserves that source wording while asking what Phrontis, gastropod and genus can confirm, complicate or overturn.
Why this record matters
“Phrontis (gastropod)” is worth following because a concise public description often conceals a longer documentary argument. Here, Phrontis, gastropod and genus provides the most credible route into that argument.
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 18, 2026. The linked authority identifier is Q25208234. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1826, 1847, 1845 and 1835.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. 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.
