ABSTRACT Three-dimensional finite element analyses were performed on the cranium of the horned theropod Carnotaurus sastrei to assess how it would have performed mechanically during biting and frontal butting. This technique proved to be an effective tool to provide a better understanding of the cranial functional morphology of C. sastrei. The analyses indicated that the jaw-closing musculature of C. sastrei would have played a key role in diminishing the stress level on the cranium during… Expand

Finite element and morphological analysis in extant mammals’ claws and quaternary sloths’ ungual phalanges
TLDR
The results obtained for the fossils and the extant species were able to indicate possible habits for these Pleistocene ground sloths, and the three mylodontid sloths: G. robustum, L. armatus and S. leptocephalum showed a preference for strenuous activities such as digging, while M. jeffersonii and M. americanum learned more towards a less specific locomotor habit, such as generalised terrestrial mammals.

Craniofacial biomechanics and functional and dietary inferences in hominin paleontology.
TLDR
This model serves to emphasize the need for caution in the application of FEA in paleoanthropological enquiry, and provides a critical examination of one such study of the trophic adaptations of Australopithecus africanus. Expand
Jaw biomechanics and the evolution of biting performance in theropod dinosaurs
  • M. Sakamoto
  • Biology, Medicine
  • Proceedings of the Royal Society B: Biological Sciences
  • 2010
TLDR
There is a strong phylogenetic signal in theropod biomechanical profiles, indicating that evolution of biting performance does not depart from Brownian motion evolution, and phylogenetically unexpected major shifts in function space occupation can be observed at the origins of some clades. Expand
The importance of muscle architecture in biomechanical reconstructions of extinct animals: a case study using Tyrannosaurus rex
TLDR
Detailed comparison of previous models of T. rex bite force reveals that estimations of muscle fibre lengths and architecture are the principal source of disagreement between studies, and therefore that these parameters represents the greatest source of uncertainty in these reconstructions, and potentially therefore extinct animals generally. Expand
Cranial myology and bite force performance of Erlikosaurus andrewsi: a novel approach for digital muscle reconstructions
TLDR
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. Expand
Edentulism, beaks, and biomechanical innovations in the evolution of theropod dinosaurs
TLDR
Results of finite-element analyses provide evidence that keratinous beaks play an important role in enhancing cranial stability by mitigation stress and strain during feeding and represent an evolutionary innovation developed early in derived theropod dinosaurs, distinct to postulated mass-saving benefits associated with the origin of flight. Expand
Mandible strength and geometry in relation to bite force: a study in three caviomorph rodents
TLDR
This work assesses the structural strength of the mandibles of three caviomorph species that show remarkable differences in ecology, behavior and bite force and concludes that the mandible of C. talarum is better able to withstand strong incisor bites. Expand
Cranial Musculature in Herbivorous Dinosaurs: A Survey of Reconstructed Anatomical Diversity and Feeding Mechanisms
TLDR
Cranial muscle reconstructions in herbivorous dinosaurs are reviewed and informative anatomical characters are compared across 142 dinosaur genera, revealing many combinations of anatomical traits influencing a diversity of feeding mechanisms. Expand
STRUCTURAL PERFORMANCE OF TETANURAN THEROPOD SKULLS, WITH EMPHASIS ON THE MEGALOSAURIDAE, SPINOSAURIDAE AND CARCHARODONTOSAURIDAE
TLDR
This study uses the engineering technique finite element analysis to reconstruct feeding-related stress and strain in the skulls of seven theropod dinosaurs, showing a significant size-related trend, with large taxa experiencing greater stresses than smaller taxa. Expand
Ceratosaur palaeobiology: new insights on evolution and ecology of the southern rulers
TLDR
The results presented here suggest that abelisaurids had different soft tissues on the skull which might have been associated with evolution of a strong cervicocephalic complex and should have allowed derived taxa to have low-displacement headbutting matches. Expand

  • Biology, Medicine

TLDR
Finite–element–generated stress–strain patterns are consistent with T. rex cranial morphology: the maxilla–jugal suture provides a tensile shock– absorption function that reduces localized tension yet ‘weakens’ the skull overall. Expand
Cranial design and function in a large theropod dinosaur
TLDR
This work has generated the most geometrically complete and complex FEA model of the skull of any extinct or extant organism and used this to test its mechanical properties and examine, in a quantitative way, long-held hypotheses concerning overall shape and function. Expand
Evidence for advanced carnivory in fossil armadillos (Mammalia: Xenarthra: Dasypodidae)
TLDR
The features suggest that Macroeuphractus occupied an extreme position in the carnivorous-omnivorous feeding behavior of euphractines, and its large size indicates that it could have easily preyed on hare-sized vertebrates. Expand
ON THE PALAEOBIOLOGY OF THE SOUTH AMERICAN HORNED THEROPOD CARNOTAURUS SASTREI BONAPARTE
TLDR
It is concluded that Car- notaurus was an agile theropod, with a somewhat fast rather than strong bite, and that it must have used the horns in intraspecific fights or even in hunting. Expand
Bite-force estimation for Tyrannosaurus rex from tooth-marked bones
TLDR
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. Expand
Cranial strength in relation to estimated biting forces in some mammals
TLDR
Whether the bending strength of the skull in some mammals correlates with the maximal loads imposed through the masticatory apparatus is examined, using the methods of beam theory. Expand
Forces of biting, body size, and masticatory muscle tension in the opossum Didelphis virginiana
TLDR
The authors maximally stimulated the jaw adducting muscles of ten opossums under anaesthesia and recorded the force output between the first molars, showing some scatter, but significant regressions were obtained of peak force of biting on both body weight and skull length. Expand
The ontogeny of bite-force performance in American alligator (Alligator mississippiensis)
TLDR
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. Expand
Mechanical factors in the evolution of the mammalian secondary palate: A theoretical analysis
TLDR
The mammalian secondary palate may be interpreted as one of a number of methods, seen in the mammal‐like reptiles, for strengthening the rostrum. Expand
Archosaur adductor chamber evolution: Integration of musculoskeletal and topological criteria in jaw muscle homology
TLDR
A new and robust view of jaw muscle homology is provided and the first synthesized nomenclature of sauropsid musculature is introduced using multiple lines of evidence, indicating multiple topological criteria are necessary for interpretations of soft‐tissue homology and warrant further investigation into character congruence and developmental connectivity.
