Claim ledger

taxonomy · medium

SGS-UM 2009-002 was recovered as a stem catarrhine in a 36-character, 19-taxon analysis; this is a sampled topology, not a direct ancestor claim.

claim:taxon:saadanius:taxonomy

biogeography · medium

The profile is limited to the Middle Shumaysi Formation in western Saudi Arabia and does not establish a global catarrhine origin centre.

claim:taxon:saadanius:biogeography

ecology · medium

Dentition permits a bounded dietary inference, while the partial cranium does not preserve locomotion, habitual habitat or feeding behaviour.

claim:taxon:saadanius:ecology

morphology · medium

The holotype preserves much of the face, palate and dentition together with a tubular ectotympanic documented by photographs and micro-CT.

claim:taxon:saadanius:morphology

fossil-range · medium

The 29–28 Ma envelope follows the study’s biochronological context and is not a direct specimen date, crown-catarrhine FAD or divergence time.

claim:taxon:saadanius:fossil-range

Known limits

A missing branch or fossil occurrence does not imply biological absence. Internal nodes are not calibrated divergence estimates.
