  author={Paul M. Gignac and Peter J Makovicky and Gregory M. Erickson and Robert. Walsh},
ABSTRACT We report the discovery of a specimen of Tenontosaurus tilletti from the Cloverly Formation that bears lesions we interpret as bite marks of Deinonychus antirrhopus. Some of the bite marks are in the form of exceptionally deep punctures through the long bone cortices. These provide a rare opportunity to estimate the bite-force capacities of this taxon through tooth indentation simulations. These experiments showed that approximately 4100 N of bite force were required to generate one of… 
Bite force estimates in juvenile Tyrannosaurus rex based on simulated puncture marks
Bite force estimates for a juvenile Tyrannosaurus rex based on mechanical tests designed to replicate bite marks previously attributed to a T. rex of approximately 13 years old are presented and the implications for feeding mechanisms, feeding behaviors, and ontogenetic niche partitioning are discussed.
Cranial myology and bite force performance of Erlikosaurus andrewsi: a novel approach for digital muscle reconstructions
A detailed reconstruction of the adductor musculature of the Cretaceous therizinosaur Erlikosaurus andrewsi is presented based on a stepwise and iterative approach, which indicates that the low bite performance was mainly used for leaf‐stripping and plant cropping, rather than active mastication or chewing processes.
The First Healed Bite Mark and Embedded Tooth in the Snout of a Middle Permian Gorgonopsian (Synapsida: Therapsida)
This work describes, for the first time, the occurrence of a tooth embedded in the snout of a gorgonopsian, surrounded by a bony callus, which demonstrates that the animal was still alive after the attack and healed.
The Biomechanics Behind Extreme Osteophagy in Tyrannosaurus rex
It is shown that bone pulverization was made possible through a combination of prodigious bite forces and tooth pressures promoting crack propagation in bones, and repetitive, localized biting, which allowed T. rex to finely fragment bones and more fully exploit large dinosaur carcasses for sustenance relative to competing carnivores.
Mega-Bites: Extreme jaw forces of living and extinct piranhas (Serrasalmidae)
The bite capabilities and potential feeding ecology of the extinct giant Miocene piranha, Megapiranha paranensis, are reconstructed and a mechanistic rationale for their predatory dominance among past and present Amazonian ichthyofaunas is provided.
An actualistic and phylogenetic approach to identifying and interpreting crocodylian bite marks
A 2D morphometric analysis of Alligator mississippiensis crania from captive and wild specimens revealed that the effects of ontogeny introduced a stronger signal than captivity, implying that while using captive crocodylians in fine scale analyses should be avoided, they are suitable for gross scale research, such as bite mark analyses.
A comparative analysis of ontogenetic bite‐force scaling among Crocodylia
It is suggested that intraspecific bite-force scaling for crocodylians with feeding ecologies comparable with those of extant forms has likely remained evolutionarily static during their diversification.
Bite marks on the frill of a juvenile Centrosaurus from the Late Cretaceous Dinosaur Provincial Park Formation, Alberta, Canada
It is difficult to determine the likely tracemaker(s) but the strongest candidate is a small-bodied theropod such as a dromaeosaur or juvenile tyrannosaur.
Feeding traces attributable to juvenile Tyrannosaurus rex offer insight into ontogenetic dietary trends
Comparisons reveal that the tooth marks present on the vertebra closely match the maxillary teeth of a late-stage juvenile Tyrannosaurus rex specimen histologically determined to be 11–12 years of age, demonstrating that late- stage juvenile and subadult tyrannosaurs were already utilizing the same large-bodied food sources as adults despite lacking the bone-crushing abilities of adults.


Bite-force estimation for Tyrannosaurus rex from tooth-marked bones
The discovery of skeletal remains with bite marks from Tyrannosaurus rex makes it possible to estimate, through indentation simulations on bovine ilia, the bite forces produced by T. rexduring feeding, and these estimates rival the largest bite forces determined for any taxon to date and suggest thatT.
Development of bite strength and feeding behaviour in juvenile spotted hyenas (Crocuta crocuta)
It is demonstrated that juvenile hyenas had not achieved adult feeding performance levels at 12 months of age, when they are typically weaned in the wild, which suggests that recently weaned cubs may be at an increased risk of starvation and that selection might favour later weaning times.
The ontogeny of bite-force performance in American alligator (Alligator mississippiensis)
The bite-force values for adult A. mississippiensis are the highest measured for any living animal and represent the first measures for a large crocodilian, and provide the first documentation of how bite force changes during ontogeny in a reptile.
Head-biting behavior in theropod dinosaurs: Paleopathological evidence
Cranial material of Sinraptor dongi (Upper Jurassic, Xinjiang, China), Gorgosaurus libratus, Daspletosaurus torosus (Upper Cretaceous, Alberta, Canada), and other large theropod dinosaurs exhibit
Dental morphology and variation in theropod dinosaurs: implications for the taxonomic identification of isolated teeth.
A quantitative methodology designed to provide defensible identifications of isolated teeth using Tyrannosaurus as a comparison taxon and results indicate that expanding the standard should facilitate the identification of numerous types of isolated theropod teeth.
Maximum Bite Force and Prey Size of Tyrannosaurus rex and Their Relationships to the Inference of Feeding Behavior
This analysis establishes boundary conditions for possible predator/prey relationships among other dinosaurs, as well as between these two taxa, and shows that adult Triceratops horridus fall well within the size range of potential prey that are predicted to be available to a solitary, predaceous T. rex.
Taphonomy and paleobiological implications of Tenontosaurus-Deinonychus associations
ABSTRACT The discovery of a nearly complete skeleton of Tenontosaurus tilletti and closely associated multiple shed teeth of the dromaeosaur Deinonychus antirrhopus provides evidence that may support
Komodo monitor (Varanus komodoensis) feeding behavior and dental function reflected through tooth marks on bone surfaces, and the application to ziphodont paleobiology
Both feeding behavior and tooth marks indicate that ziphodont crowns are ideal for defleshing by being drawn distally through a carcass by Varanus komodoensis, the Komodo monitor.
A partial skeleton of the tyrannosaurid dinosaur Aublysodon from the Upper Cretaceous of New Mexico
A fragmentary tyrannosaurid skull and postcranial skeleton from the Kirtland Shale of northwestern New Mexico is the most complete specimen of a carnivorous dinosaur known from these strata. The
Bite forces, canine strength and skull allometry in carnivores (Mammalia, Carnivora)
Previous hypotheses of large taxon differences in canine bending strengths, so that felids have stronger canines than canids, are corroborated when actual bite forces at the upper canine are ignored, and ursids seem to have strongerCanines than felids.
