An integrated approach to understanding the role of the long neck in plesiosaurs [PDF]
Acta Palaeontologica Polonica, 2017 The evolution and function of the long neck in plesiosaurs, and how the problems associated with stiffness or flexibility were overcome during feeding, or rapid swimming during predator avoidance, are explored, and a new interpretation for the function ...

Ontogeny, muscle scars, colour pattern and predation marks in a Silurian orthoceratid cephalopod [PDF]
Acta Palaeontologica PolonicaMuscle scars, embryonic shell, colour pattern and intraspecific variation are known together in a very limited numberof straight shelled cephalopods, leading to uncertainty in the classification of the subclass Orthoceratoidea.

The Anatomical Record, EarlyView.Abstract Dental microwear texture analysis (DMTA) has emerged as a valuable method for investigating the feeding ecology of vertebrates. Over the past decade, three‐dimensional topographic data from microscopic regions of tooth surfaces have been collected, and surface texture parameters have been published for both extant and fossil species.

Atmospheric CO2 effect on stable carbon isotope composition of terrestrial fossil archives
Nature Communications, 2018 The effect of CO2 concentrations on 13C/12C ratios in C3 plants, comprising most of Earth’s vegetation, is currently debated. Here, using ice core records and plant and animal fossils, Hare et al.

Skeletal pathologies in extant crocodilians as a window into the paleopathology of fossil archosaurs
The Anatomical Record, EarlyView.Abstract Crocodilians, together with birds, are the only extant relatives to many extinct archosaur groups, making them highly important for interpreting paleopathological conditions in a phylogenetic disease bracketing model. Despite this, comprehensive data on osteopathologies in crocodilians remain scarce.
