Abstract Sex is an important driver of variation in behaviour, ecology and physiology. Sex identification in the Critically Endangered European eel (Anguilla anguilla) currently requires fish sacrifice, or the use of morphological differences such as body length, which can be inaccurate in certain habitats and at intermediate body lengths.

This study investigates the morphology and osteo‐histology of the wing skeleton of the world's first gliding reptiles, showing how it differs from those of extant gliding lizards, yet is also convergently similar. These findings pave the way for future biomechanical studies on the gliding locomotion of these emblematic fossil animals. Abstract The Late

Phylogeny, biogeography and diversification patterns of side-necked turtles (Testudines: Pleurodira) [PDF]
Pleurodires or side-necked turtles are today restricted to freshwater environments of South America, Africa– Madagascar and Australia, but in the past they were distributed much more broadly, being found also on Eurasia, India and North America, and ...

Fossil finds from three Middle Miocene sites in Poland reveal the northernmost known presence of trionychid turtles in Europe, tentatively identified as Trionyx cf. vindobonensis, suggesting a warmer climate that supported thermophilic species in Central Europe during this period. Abstract Modern trionychids (Testudines, Cryptodira) have a pan‐tropical
