The function of serrated teeth is analyzed by experimental comparison with the action of artificially made steel blades. Serrated blades cut compliant materials with a grip-and-rip mechanism, whereas smooth, sharp blades cut by concentrating a large downward force on a tiny area. Tyrannosaurid teeth from the Cretaceous Judith River Formation bear rows of serrations that have thick, rounded enamel caps, gripping slots between neighboring serrations, thick enamel bodies inside the teeth… 

Wear facets and enamel spalling in tyrannosaurid dinosaurs

Numerous paleontologists have noted wear facets on tyrannosaurid lateral teeth over the past century. While several workers have proposed explanations for these features, there remains to this day no

Convergent dental adaptations in the serrations of hypercarnivorous synapsids and dinosaurs

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.

A Functional Explanation for Denticulation in Theropod Dinosaur Teeth

The functional model proposed here tests the hypothesis that denticles will not exist in areas that do not frequently contact the substrate, and predicts the direction of tooth movement through the curvature of the tip/apex almost always predicted less extensive denticulation.


The morphology and enamel ultrastructure of serrated teeth of crocodiles is compared. The sample is composed by isolated teeth attributed to the iberoccitanian form (Eocene of the Duero basin, Spain)

Performance of teeth of lingcod, Ophiodon elongatus, over ontogeny.

There is a shift in tooth function from vomerine to premaxillary teeth over ontogeny of lingcods, and in juvenile lingcod, vomerines function more effectively during initial puncture, suggesting increasing functional performance in retaining prey.


The presence and nature of these wounds suggests that juvenile tyrannosaurid behavior included intraspecific aggression among similar-sized individuals, as has been observed in modern crocodilians.

How to best smash a snail: the effect of tooth shape on crushing load

The results show that for both shell morphologies, domed and flat teeth break shells better than cupped teeth, and teeth with tall or skinny cusps break shells best, suggesting a probable trade-off between tooth function and the structural integrity of the tooth.

The presence of muscle and tendon attachments in Sebecus suggests the adductor structure of mesoeucrocodylians is conservative and was established before divergence of the sebecosuchian and neosuchians lineages.



Transport-induced abrasion of fossil reptilian teeth: Implications for the existence of Tertiary dinosaurs in the Hell Creek Formation, Montana

The experimental transport-induced abrasion of five fossil teeth from a crocodilian and the tyrannosaurid dinosaur Albertosaurus demonstrates that enamel-coated teeth are minimally affected by

Functional Morphology and the Evolution of Cats

Three basic morpho types are proposed for cats on the basis of their upper canines: conical-toothed cats with short, unserrated canines having a round cross-section; scimitar-tooting cats having short, broad canines; and dirk­ toothed cats having long, slender canines which usually have fine serrations.

An Introduction to the Osteology of the Mammalia

This new edition of the “Osteology of the Mammalia” is welcomed with much pleasure and there is a new outline diagram of special interest introduced to illustrate the mutual relations of the various elements of what may be termed the typical mammalian skull.

Although the known parts of the skeleton are at present very limited, they are yet sufficient to determine the place of the animal in the zoological system and show the creature to have been oviparous, and to have belonged to the order of Saurians or Lizards.
