Begin with the source’s own compact description: “Geodia atlantica” is species of sponge. The dossier treats that line as a proposition to test through Geodia, atlantica and species, not as a finished interpretation.
Why this record matters
The phrase “species of sponge” 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.
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 Mar 8, 2021. The linked authority identifier is Q19943298. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2015, 1475, 1516 and 2013.
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.
