The CT technique was first applied to observing the nasal cavity ofIkechosaurus sunailinae. The results indicate that the nasal cavity is very complex, and it was divided into two parts: the posterior-upper part and the anterior-lower one. These control olfaction and thermoregulation respectively. The partial loss of pineal systems suggests that this animal may have been evolving toward endothermy. Therefore,Ikechosaurus may have had a strong ability to thermoregulate, thus keeping a high level… 
The internal cranial anatomy of Champsosaurus (Choristodera: Champsosauridae): Implications for neurosensory function
TLDR
Comparisons with lepidosaurs and archosauromorphs demonstrates that the semicircular canals of Champsosaurus are most similar to those of aquatic reptiles, suggesting that Champsaurus was well adapted for sensing movement in an aquatic environment and represents the first morphometric analysis of semicircul canals across Diapsida.
The internal cranial anatomy of Champsosaurus lindoei and its functional implications
TLDR
The presence of the putative neomorphic bone is confirmed, which may be homologous with the pre-existing stapes, or developed through incomplete fusion of dermatocranial ossification centres, and geometric morphometric analyses of the semicircular canals suggest that Champsosaurus were well adapted for an aquatic lifestyle.
Computed tomography analysis of the cranium of Champsosaurus lindoei and implications for the choristoderan neomorphic ossification
TLDR
The cranial anatomy of the choristodere Champsosaurus lindoei was examined using high‐resolution micro‐computed tomography scanning and it was found that the paired gaps on the ventral surface of the skull do pertain to the fenestrae ovales, an unusual arrangement that may be convergent with some plesiosaurs, some aistopods, and some urodeles.
A New Choristodere from the Cretaceous of Mongolia
TLDR
Phylogenetic analysis with the addition of data from the new specimen confirms the basal position of Tchoiria in Simoedosauridae and provides new information about the genus.

TLDR
The presence of respiratory turbinals in these advanced mammallike reptiles suggests that the evolution of “mammalian” oxygen consumption rates may have begun as early as the Late Permian and developed in parallel in therocephalians and cynodonts.
Aspects of some anatomical structures of Champsosaurus(Reptilia: Eosuchia)
TLDR
The essentially complete articulated postcranial skeleton indicates that the ribcage was relatively rigid and Gastralia functioned with this rigid unit in compression and expansion of the pleural cavity and lowered the center of gravity to assist in underwater stability.
