Lejopyge laevigata
species of trilobite (fossil)
Lejopyge laevigata is a species of agnostid trilobite belonging to the genus Lejopyge. It existed during the Guzhangian to the Paibian Age (around 500.5 to 497 million years ago) of the Cambrian. It has a cosmopolitan distribution and is an important index fossil in biostratigraphy.
Description
Lejopyge laevigata exhibits a cephalon and pygidium that are smooth and almost featureless (effaced). Both possess axial furrows that gradually become shallower until they disappear distally. They surround the rear edges of the glabella (reaching about as far or a little past the basal glabellar lobes) and the anterior end of the central lobe of the pygidium. Basal furrows are also present. The genae ("cheeks") are usually smooth, but in extremely rare cases they may possess small pits (scrobicules) of moderate depth. The border around the pygidium is uniform in width at the back and narrows towards the front. Like all members of the suborder Agnostina, Lejopyge laevigata is completely blind.
Begin with the source’s own compact description: “Lejopyge laevigata” is species of trilobite (fossil). The dossier treats that line as a proposition to test through Lejopyge, laevigata and species, not as a finished interpretation.
Why this record matters
The phrase “species of trilobite (fossil)” 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.
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 18, 2026. The linked authority identifier is Q6520530. None of the 0 selected statements returned an explicit reference.
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.
