Strudiella devonica was originally described as a Late Devonian insect, but a later primary re-investigation rejected that identification; its placement is retained as a contested arthropod interpretation.
claim:taxon:strudiella:taxonomyStrudiella
The single, nearly complete Strud specimen was described as a Late Devonian insect, but a subsequent re-investigation rejected that identification; the profile preserves both the named material and the unresolved arthropod affinity.

Claim ledger
The profiled Strudiella specimen comes from Upper Devonian freshwater sediments at the Strud locality in Belgium; this records one deposit and not a complete geographic distribution.
claim:taxon:strudiella:biogeographyThe original reconstruction inferred a terrestrial, probably omnivorous arthropod from the Strud mandible interpretation, but neither feeding behaviour nor a population-wide ecological guild is directly observed.
claim:taxon:strudiella:ecologyThe nearly complete Strudiella specimen preserves a segmented body, antennae and legs; the proposed dicondylic mandibles and pterygote features are disputed after re-examination.
claim:taxon:strudiella:morphologyThe approximately 365 Ma display point is the Strud specimen's Late Devonian deposit age, not a global Strudiella range, insect FAD or arthropod lineage origin date.
claim:taxon:strudiella:fossil-rangeKnown limits
- A missing branch or fossil occurrence does not imply biological absence. Internal nodes are not calibrated divergence estimates.
