Tujiaaspis vividus is a galeaspid represented by articulated Huixingshao Formation material; its placement is a published phylogenetic interpretation and is not presented as direct ancestry to jawed vertebrates.

Claim ledger
The figured Tujiaaspis material comes from the Huixingshao Formation at Lianghe village, Yongdong town, Xiushan County, Chongqing Municipality, and Kapeng Reservoir in Baojing County, Xiangxi, Hunan, South China; these are sampled localities, not a global distribution.
claim:taxon:tujiaaspis:biogeographyThe study reconstructs continuous ventrolateral fins and models their passive lift, but diet, life habitat, trophic guild and measured swimming performance remain unresolved.
claim:taxon:tujiaaspis:ecologyHolotype IVPP V26668 and paratypes IVPP V27410–V27411 preserve three unpaired dorsal fins, an approximately symmetrical hypochordal tail and continuous branchial-to-caudal ventrolateral fins.
claim:taxon:tujiaaspis:morphologyThe displayed 438.6–432.9 Ma interval is the Telychian time-scale envelope for the Huixingshao Formation Tujiaaspis sample and is not a global genus range, FAD, LAD or divergence date.
claim:taxon:tujiaaspis:fossil-rangeKnown limits
- A missing branch or fossil occurrence does not imply biological absence. Internal nodes are not calibrated divergence estimates.
