Source-derived summary

Guttulina is a genus of nodosariacean forams belonging to the Polymorphinidae and subfamily Polymorphinidae. The test is ovoid to elongate, inflated chambers added in a quinqueloculine spiral series, 144 deg. apart, each successive chamber extending further from the base but strongly overlapping. Sutures depressed, aperture radiate. As with all Nodosarioidea the wall is of finely perforate, radial laminated calcite.

Editorial summary

“Guttulina” enters the record as genus of forams, amoeboid protists. Crown Archives preserves that source wording while asking what Guttulina, genus and forams can confirm, complicate or overturn.

Editorial reviewUseful for establishing the present vocabulary of the subject while preserving a route back to the evidence on which that vocabulary rests. The current lead gives the account dated anchors—1964, 2012—that can be checked directly. The selected authority fields contribute no independent date. Its strongest next move is a source search built around Guttulina, genus and forams.
Editorial analysis

Why this record matters

“Guttulina” is worth following because a concise public description often conceals a longer documentary argument. Here, Guttulina, genus and forams provides the most credible route into that argument.

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 Apr 29, 2026. The linked authority identifier is Q5621942. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1964 and 2012.

Critical limits

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.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
