2025 in paleoichthyology
| |||
|---|---|---|---|
This list of fossil fish research presented in 2025 is a list of new fossil taxa of jawless vertebrates, placoderms, cartilaginous fishes, bony fishes, and other fishes that were described during the year, as well as other significant discoveries and events related to paleoichthyology that occurred in 2025.
Cartilaginous fishes
[edit]Cartilaginous fish research
[edit]- Evidence from the study of oxygen isotope composition of teeth of Cretoxyrhina mantelli, Cretalamna appendiculata, Scapanorhynchus texanus, Squalicorax kaupi, Squalicorax pristodontus and Ptychodus mortoni from the Upper Cretaceous strata from the Gulf Coastal Plain, interpreted as likely indicative of increased body temperature of P. mortoni and indicative of active heating and migration from warmer waters by C. mantelli, is presented by Comans, Tobin & Totten (2025)[1]
- Amadori et al. (2025) reconstruct the lower crushing plate of Ptychodus decurrens on the basis of new fossil material from the Upper Cretaceous strata in Croatia.[2]
- Greenfield (2025) reidentify the large rostrum and four fragmentary rostral denticles from the Dakhla Formation originally attributed to Onchopristis sp. by Capasso et al. (2024)[3] as Sclerorhynchoidei indet. and Sclerorhynchus cf. leptodon, respectively.[4]
