Acanthohoplites
genus of molluscs (fossil)
Acanthohoplites is an extinct genus of ammonites in the family Parahoplitidae that lived in the Aptian and Early Albian stages of the Early Cretaceous.
Taxonomy
The taxonomic position in the Treatise on Invertebrate Paleontology Pt L, 1957 placed the genus into the family Deshayesitidae. Newer classifications have revised that placement and the genus is now included into the family Parahoplitidae. Parahoplites and Hypacanthoplites are similar genera.
Description
These ammonites have a strongly ribbed shell and ammonitic suture. Early whorls are coronate, which later become round, then oval in section. Primary ribs may have swellings (bullae) at the umbilicus or are without. In early stages primary ribs branch mid flank at prominent lateral tubercles. In later stages lateral tubercles are reduced or absent and primary ribs branch simply at the umbilical shoulder or, again, mid flank. Sutural elements are subquadrate with narrow, shallow embayments.
The public source identifies “Acanthohoplites” as genus of molluscs (fossil). This brief keeps that definition visible, then builds a research path around Acanthohoplites, genus and molluscs.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Acanthohoplites”, the useful work is to connect “genus of molluscs (fossil)” to the records capable of establishing context and consequence.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated May 19, 2026. The linked authority identifier is Q3726684. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1957.
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.
