It is shown that this novel complex of dental morphology and tissues characterizes Theropoda, with the exception of species with modified feeding behaviours, suggesting that these characters are important for facilitating the hypercarnivorous diet of most theropods.

A well-preserved skull from a previously unknown growth stage for the lambeosaurine hadrosaurid Hypacrosaurus stebingeri from the Campanian of western North America allows for a direct comparison of the juvenile growth stage of all four taxa for the first time.

Comparison with similarly-sized, taxonomically determinate, and coeval hadrosaurid specimens from the Two Medicine Formation suggest that the combination of characters used to distinguish G. ericksoni as a non-hadrosurid hadrosauroid are more widely distributed or individually variable inHadrosaurids, or can be explained as the result of ontogenetic variation.
Tooth counts through growth in diapsid reptiles: implications for interpreting individual and size‐related variation in the fossil record

- 1 April 2015
The hypothesis that variation in tooth count is driven primarily by growth is rejected and growth trajectories of smaller reptilian taxa show increases in tooth counts and, although current samples are small, suggest potential correlates between tooth count trajectories and adult size.
Hidden dental diversity in the oldest terrestrial apex predator Dimetrodon.
A time-calibrated phylogenetic analysis indicates that changes in dental morphology occur in the absence of any significant changes in skull morphology, suggesting that the morphological change is associated with changes in feeding style and trophic interactions in these ecosystems.

Recommendations on the usage and interpretation of growth mark spacing/zonal thickness data, when these are likely to be unreliable, and under what conditions they can provide useful inferences for studies of growth and life history are provided.
Evolutionary Implications of Tooth Attachment Versus Tooth Implantation: A Case Study Using Dinosaur, Crocodilian, and Mammal Teeth

A comparative histological approach for describing tooth attachment and implantation in an exemplary, traditionally thecodont taxonomic group: the non-avian dinosaurs is provided.
Mineralized periodontia in extinct relatives of mammals shed light on the evolutionary history of mineral homeostasis in periodontal tissue maintenance.

- Biology, MedicineJournal of Clinical Periodontology
- 1 April 2016
Dental ankylotic condition in stem mammals was achieved through extensive alveolar bone deposition, which eventually contacted the root cementum, thus forming a calcified periodontal ligament, which was part of the normal development of the stem mammal periodontium for millions of years prior to the evolution of a permanent gomphosis in mammals.
