Odonata

Targeted sequencing of 478 loci across 136 species and 46 of 48 living families supports an updated sampled Odonata classification. Several backbone relationships remain uncertain, and the living sample does not delimit the order's fossil range or origin.

The 268–0 Ma Odonata display begins with the earliest fossil recognized as a modern odonate, Saxonagrion minutus, rather than inheriting the older Odonatoptera edge.

Targeted sequencing of 478 loci from 136 living species representing 46 of 48 living odonate families produced an updated sampled classification; unresolved backbone sections remain and the result is not a complete order history.

Saxonagrion minutus was described from the Upper Permian Salagou Formation in the Lodève Basin, France, while the modern genomic sample covers 136 species in 46 families; neither record supplies a complete Odonata distribution.

The targeted-genomics study tests classification rather than diet, habitat use, flight performance, body size or ecological guild; this profile therefore leaves those fields unassigned rather than inferring them for Odonata.

The primary fossil description attributes Saxonagrion minutus to Panodonata from preserved wing venation; the observation concerns that Upper Permian fossil and is not a diagnostic body plan for all Odonata.
