Guraleus singletoni
fossil mollusc species
Guraleus singletoni is an extinct species of sea snail, a marine gastropod mollusc, in the family Mangeliidae. Fossils of the species date to early Pliocene strata of the St Vincent Basin of South Australia and the Otway Basin of South Australia and Victoria, including the Grange Burn Formation near Hamilton, Victoria.
Description
In the original description, Powell described the species as follows:
Fusiform, with tall turreted spire. Whorls sharply angled at about two-thirds whorl height. Axials narrow, 11 per whorl, weak over shoulder, vertical on spire-whorls but arcuate and irregular over body-whorl; extending from upper suture completely over base. Spiral sculpture consisting of 4 or 5 weak threads on the shoulder and 7 weak, slightly irregular cords from the shoulder angle to lower suture. On the body-whorl the spiral cords are numerous, linear-spaced but weak, the most distinct being 12 on the anterior end. Protoconch polygyrate, conic, of 3 smooth whorls, followed by a half whorl of fine brephic axials.
The holotype of the species measures 6.5 mm (0.26 in) in length and has a diameter of 2.5 mm (0.098 in).
Taxonomy
The species was first described by A. W. B. Powell in 1944.
This brief starts where responsible research should: with the source description of “Guraleus singletoni” as fossil mollusc species. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as fossil mollusc species. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Mar 2, 2026. The linked authority identifier is Q137716099. The first chronological checks are 1944.
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
