Revisiting ‘Scomber’ voitestii
Middle Oligocene, Scomber voitestii
(Pauca 1929) turns out to be a late-surviving spiny shark (Acanthodii).
For a long time this was a puzzling specimen
until I realized that lateral spines might be present (everywhere but the anal fin). They were just hard to see.

The genus Scomber
traditionally refers to extant mackeral. This specimen referred to Scomber voitestii is not closely related to extant mackeral in the large reptile tree (LRT, 2312 taxa). So this specimen will need a new generic name.
This reexamination resolves earlier issues when S voitestii first entered the LRT basal to flatfish. The lateral spines were not yet recognized – and the skull was revised.
This appears to be a novel hypothesis of interrelationships.
If not, please provide a citation so I can promote it here.
