An ontological morphological phylogenetic framework for living and extinct ray‐finned fishes (Actinopterygii)

The Anatomical Record, EarlyView.
Abstract The ray‐finned fishes include one out of every two species of living vertebrates on Earth and have an abundant fossil record stretching 380 million years into the past.

Histology and fossil diagenesis of a pterosaur tooth from the Crato Formation (Lower Cretaceous of Brazil)

The Anatomical Record, EarlyView.
Abstract Pterosaur dental biology remains poorly understood despite its importance for comprehending feeding strategies and flight adaptations. Here, we present the first comprehensive histological analysis of an ornithocheiriform pterosaur tooth from the Lower Cretaceous Crato Formation (Santana Group, Northeast Brazil).

Does salinity make a difference—Kidney anatomy of Saimaa (Pusa saimensis) and Baltic ringed seals (Pusa hispida botnica)

The Anatomical Record, EarlyView.
Abstract As habitat salinity markedly differs between the endangered, freshwater‐dwelling Saimaa ringed seal (Pusa saimensis Nordquist, 1899) and the brackish water‐inhabiting Baltic ringed seal (Pusa hispida botnica Gmelin, 1788), we investigated whether this difference has resulted in morphological changes to their kidneys.
