Extensive target-gene and taxon sampling provides a reproducible topology and revised classification for sampled spiders. It does not establish the fossil first appearance, exact crown age or a direct ancestor of Araneae.

topology · taxonomy
An extensive sampled spider topology, not a fossil range or direct-ancestry result.
Extensive target-gene and taxon sampling provides a reproducible topology and revised classification for sampled spiders. It does not establish the fossil first appearance, exact crown age or a direct ancestor of Araneae.
claim:taxon:araneaeWheeler et al. use extensive target-gene sampling to revise relationships among living spiders, while Garwood et al. distinguish the Carboniferous Idmonarachne from true spiders by its preserved appendages; the combined classification remains a sampled and revisable hypothesis.
claim:taxon:araneae:taxonomyThe spider fossil review records Carboniferous and younger occurrences, and Wheeler et al. sample living lineages broadly for target-gene phylogeny; these fossil localities and sampled species do not form a complete geographic distribution of Araneae.
claim:taxon:araneae:biogeographyThe cited spider phylogeny and fossil-origin studies test relationships and preserved anatomy rather than diet, habitat use, locomotor performance, body size or ecological guild; those fields remain unassigned for Araneae here.
