Evolution of forelimb musculoskeletal function across the fish-to-tetrapod transition (2021)
Journal Article
Molnar, J., Hutchinson, J., Diogo, R., Clack, J., & Pierce, S. (2021). Evolution of forelimb musculoskeletal function across the fish-to-tetrapod transition. Science Advances, 7(4), https://doi.org/10.1126/sciadv.abd7457

One of the most intriguing questions in vertebrate evolution is how tetrapods gained the ability to walk on land. Although many hypotheses have been proposed, few have been rigorously tested using the fossil record. Here, we build three-dimensional m...

Femoral specializations to locomotor habits in early archosauriforms (2021)
Journal Article
Romain, P., Alexandra, H., Nesbitt, S. J., & Hutchinson, J. R. (2021). Femoral specializations to locomotor habits in early archosauriforms. Journal of Anatomy, https://doi.org/10.1111/joa.13598

The evolutionary history of archosaurs and their closest relatives is characterized by a wide diversity of locomotor modes, which has even been suggested as a pivotal aspect underlying the evolutionary success of dinosaurs vs. pseudosuchians across t...

Estimating gaits of an ancient crocodile-line archosaur through 1 trajectory optimization, with comparison to fossil trackways (2021)
Journal Article
Polet, D. T., & Hutchinson, J. R. (in press). Estimating gaits of an ancient crocodile-line archosaur through 1 trajectory optimization, with comparison to fossil trackways. Frontiers in Bioengineering and Biotechnology, https://doi.org/10.3389/fbioe.2021.800311

13 Fossil trackways provide a glimpse into the behaviour of extinct animals. However, while providing 14 information of trackmaker size, stride and even speed, the actual gait of the organism can be 15 ambiguous. This is especially true of quadrupeda...

The critical dynamic role of the tail in bipedal dinosaur locomotion (2021)
Journal Article
Bishop, P., Falisse, A., De Groote, F., & Hutchinson, J. (2021). The critical dynamic role of the tail in bipedal dinosaur locomotion. Science Advances, https://doi.org/10.1126/sciadv.abi7348

Locomotion has influenced the ecology, evolution, and extinction of species throughout history, yet studying locomotion in the fossil record is challenging. Computational biomechanics can provide novel insight by mechanistically relating observed ana... Read More about The critical dynamic role of the tail in bipedal dinosaur locomotion.

The evolutionary biomechanics of locomotor function in giant land animals (2021)
Journal Article
Hutchinson, J. (2021). The evolutionary biomechanics of locomotor function in giant land animals. Journal of Experimental Biology, https://doi.org/10.1242/jeb.217463

Giant land vertebrates have evolved more than 30 times, notably in dinosaurs and mammals. The evolutionary and biomechanical perspectives considered here unify data from extant and extinct species, assessing current theory regarding how the locomotor...

Limb myology and muscle architecture of the Indian rhinoceros Rhinoceros unicornis and the white rhinoceros Ceratotherium simum (Mammalia: Rhinocerotidae) (2021)
Journal Article
Hutchinson, J., Etienne, C., & Houssaye, A. (2021). Limb myology and muscle architecture of the Indian rhinoceros Rhinoceros unicornis and the white rhinoceros Ceratotherium simum (Mammalia: Rhinocerotidae). PeerJ, https://doi.org/10.7717/peerj.11314

Land mammals support and move their body using their musculoskeletal system. Their
musculature usually presents varying adaptations with body mass or mode of locomotion.
Rhinocerotidae is an interesting clade in this regard, as they are heavy anima... Read More about Limb myology and muscle architecture of the Indian rhinoceros Rhinoceros unicornis and the white rhinoceros Ceratotherium simum (Mammalia: Rhinocerotidae).

Predictive Simulations of Musculoskeletal Function and Jumping Performance in a Generalized Bird (2021)
Journal Article
Bishop, P., Falisse, A., De Groote, F., & Hutchinson, J. (in press). Predictive Simulations of Musculoskeletal Function and Jumping Performance in a Generalized Bird. Integrative Organismal Biology, https://doi.org/10.1093/iob/obab006

Jumping is a common, but demanding, behavior that many animals employ during everyday activity. In contrast to jump-specialists such as anurans and some primates, jumping biomechanics and the factors that influence performance remains little studied...
