Tooth morphology and development can provide valuable insights into the feeding behaviour and evolution of extinct organisms. The teeth of Theropoda, the only clade of predominantly predatory dinosaurs, are characterized by ziphodonty, the presence of serrations (denticles) on their cutting edges. Known today only in varanid lizards, ziphodonty is much more pervasive in the fossil record. Here we present the first model for the development of ziphodont teeth in theropods through histological… 

Convergent dental adaptations in the serrations of hypercarnivorous synapsids and dinosaurs

TLDR
The same denticles and interdental folds form the cutting edges in the teeth of a Permian gorgonopsian synapsid, extending the temporal and phylogenetic distribution of this dental morphology and demonstrating that the first iteration of this feature appeared in non-mammalian synapsids.

(Teeth of theropod dinosaurs and dietary implications)

Isolated theropod teeth are the most common elements of this dinosaur clade found in the fossil record. This has led to the development of different qualitative, quantitative and phylogenetic

The distribution of dental features in non-avian theropod dinosaurs: Taxonomic potential, degree of homoplasy, and major evolutionary trends

TLDR
The authors' observations improve the taxonomic utility of theropod teeth and in some cases can help make isolated teeth useful as biostratigraphic markers, and should be a priority for investigations seeking to classify isolated teeth.

Permian hypercarnivore suggests dental complexity among early amniotes

The oldest known complex terrestrial vertebrate community included hypercarnivorous varanopids, a successful clade of amniotes with wide geographic and temporal distributions. Little is known about

Histology of spinosaurid dinosaur teeth from the Albian-Cenomanian of Morocco: Implications for tooth replacement and ecology

High numbers of spinosaurid teeth found in Morocco suggest that this clade was very abundant during the "Mid-"Cretaceous in northern Africa. Several reasons have been proposed to account for this

Ultramicrostructural reductions in teeth: implications for dietary transition from non-avian dinosaurs to birds

TLDR
Different lines of evidence all suggest a large reduction in biting force affecting the evolution of teeth in the dinosaur-bird transition, suggesting changes in teeth microstructure and associated dietary shift may have contributed to the early evolutionary success of stemward birds in the shadow of other non-avian theropods.

Tooth development, histology, and enamel microstructure in Changchunsaurus parvus: Implications for dental evolution in ornithopod dinosaurs

TLDR
Tooth histology and development in the "middle" Cretaceous ornithischian dinosaur Changchunsaurus parvus is described, and wavy enamel is suggested to have evolved in association with a shearing-type dentition in a roughly symmetrically-enameled crown.

Amniote Dental Histology, Development, and Variation: Perspectives From the Fossil Record

TLDR
By comparing histological sections of a large sample of modern and extinct amniotes, this thesis establishes tooth tissue homology across several major amniote groups and shows that even mammals and crocodilians possess the most complex forms of tooth attachment.

Peculiar macrophagous adaptations in a new Cretaceous pliosaurid

TLDR
It is indicated that Early Cretaceous marine reptile teeth with serrated carinae cannot be unequivocally assigned to metriorhynchoid crocodylomorphs and the known diversity of dental adaptations seen in Sauropterygia, the longest lived clade of marine tetrapods are extended.

Hidden dental diversity in the oldest terrestrial apex predator Dimetrodon.

TLDR
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.

DENTICLE MORPHOMETRICS AND A POSSIBLY OMNIVOROUS FEEDING HABIT FOR THE THEROPOD DINOSAUR TROODON

TLDR
The denticle morphometrics of Troodon may be a reflection of the inclusion of a significant portion of plant matter in its diet compared to that of other theropods, and may reflect a feeding habit in Troodon that involved the processing of asignificant amount of plant Matter.

The development of complex tooth shape in reptiles

TLDR
Whether the processes used to form such morphologies are conserved between divergent lizards and whether the underlying mechanisms share similarities with those of mammals is discussed.

Semiaquatic adaptations in a giant predatory dinosaur

TLDR
Adaptations for a semiaquatic lifestyle in the dinosaur Spinosaurus aegyptiacus are described, including retraction of the fleshy nostrils to a position near the mid-region of the skull and an elongate neck and trunk that shift the center of body mass anterior to the knee joint.

HETERODONTY IN THE EUROPEAN PHYTOSAUR NICROSAURUS KAPFFI AND ITS IMPLICATIONS FOR THE TAXONOMIC UTILITY AND FUNCTIONAL MORPHOLOGY OF PHYTOSAUR DENTITIONS

TLDR
The tooth morphology suggests that the more derived, tripartite phytosaur dentition is differentiated functionally into greatly enlarged anterior teeth probably used to kill smaller prey instantly by stabbing, strong posterior premaxillary teeth to seize and subdue large-sized prey, and trenchant posterior maxilla teeth to effectively dismember larger prey items.

Abstract Exceptionally large teeth attributable to the theropod genus Troodon are abundant in Upper Cretaceous rocks (Campanian–Maastrichtian) of northern Alaska. The dominance of low-angle light in

The Evolution of Extreme Hypercarnivory in Metriorhynchidae (Mesoeucrocodylia: Thalattosuchia) Based on Evidence from Microscopic Denticle Morphology

TLDR
A cladistic analysis shows that ziphodont dentition may have evolved independently in Dakosaurus and Geosaurus, or been acquired earlier by their common ancestor and secondarily lost in Torvoneustes and related taxa.

TLDR
It is suggested that the early differentiation in squamate unicuspid teeth at cap stage correlates with a more rudimentary tooth crown shape, and the enamel epithelial bulge of the gecko may be more functionally analogous to the secondary enamel knot of mammals than the primary enamel Knot of mammals.
