Histovariability and fossil diagenesis of Pissarrachampsa (Pseudosuchia, Notosuchia, Baurusuchidae) from the Upper Cretaceous of Southeast Brazil

The Anatomical Record, EarlyView.
Abstract Notosuchians were key components of western Gondwanan Cretaceous ecosystems in terrestrial predator niches and exhibited remarkable taxonomic and ecological diversity. Previous research has explored their physiology, metabolism, and histology, revealing varied growth patterns and life history strategies.

Root canal morphology of mandibular premolars

The Journal of the American Dental Association, 1978
Four hundred mandibular first premolars and 400 mandibular second premolars were decalcified, injected with dye, and made transparent to determine the number of root canals, their type, the ramifications of the main root canal, the location of apical foramina and transverse anastomoses, and the frequency of apical deltas.

Tooth row allometry in domestic rabbits and nondomestic lagomorphs: Evidence for a decoupling of body and tooth row size changes in evolutionary time

The Anatomical Record, EarlyView.
Domestic rabbits of different body sizes differ disproportionately in the length of their tooth row or the length of their diastema. Abstract In various domestic mammals, smaller breeds tend to have proportionally larger teeth, whereas this is not a universal trend across mammals.

Using cone beam computed thomography in planning the extraction of impacted third molars [PDF]

Praxis Medica, 2016
The panoramic radiography is the most used diagnostic imaging method in planning impacted lower third molar extractions. However, often panoramic radiography does not provide enough information in treatment planning for performing safely surgical ...

Description of the skull, braincase, and dentition of Moschognathus whaitsi (Dinocephalia, Tapinocephalia), and its palaeobiological and behavioral implications

The Anatomical Record, EarlyView.
Abstract A subadult Moschognathus whaitsi from the Eastern Cape Province, South Africa, was scanned using synchrotron radiation X‐ray computed tomography (SRXCT). Its subadult state allowed the cranial bones and teeth to be identified and individually reconstructed in 3D.

The revision of baphetids from the Middle Pennsylvanian of the Czech Republic: Morphology, ontogeny, palaeoecology, and the reassessment of the phylogeny of Baphetoidea

The Anatomical Record, EarlyView.
Abstract The baphetoids represent a clade of the Carboniferous stem‐tetrapods (Middle Mississippian—Middle Pennsylvanian) with a characteristic extension of the orbits into antorbital vacuities, which formed keyhole‐shaped openings on the skull. The more derived baphetids were crocodile‐like piscivores frequently occurring in coal‐bearing lacustrine ...
