Ray-finned fish research
- Cooper (2024) describes fossil material of Pachycormus macropterus from the Toarcian strata in Normandy (France) representing the first direct evidence of cannibalism in a pachycormiform fish reported to date.[8]
- Redescription of Whitephippus tamensis is published by Davesne et al. (2024), who interpret this taxon as an early member of Lampriformes, likely related to extant opahs and oarfishes and providing the earliest known evidence of adaptation of lampriforms to the pelagic environment.[9]
