A Quantitative Analysis of the Manus Musculature in Tapirs (Perissodactyla: Tapiridae)
Tapirs (Perissodactyla: Tapiridae) show evidence in their forefoot bones that suggest clear differences in the way their load is distributed during locomotion. Here, we also found corresponding diffe...

In my latest (and long overdue) blog post, I give a short account of some work that was published in the summer looking at tapir hand muscles, and their internal architecture. Hopefully interesting for biologists, conservationists, and veterinarians alike! Enjoy!

Hands up who loves tapirs!
Eugh, oh dear it's been a LOOONG time since I posted anything. I have been super busy with research and teaching this past year, and unfortunately you fine folks have been left out. But no longer. I have finally managed to find a little time to sit down and write up some bloggy-business for a couple of publications that have come out this year!

New paper! Led by @knapprew.bsky.social, we show that jaw shape in pelagiarian fishes diversified early in their evolution. Surprisingly, jaw shape is highly correlated with habitat, but not diet & with different optimisations for mechanical advantage during closing. academic.oup.com/evlett/advan...

Your body has tendons, your robots should too! Our new paper in Advanced Science highlights how adding tendons to muscle-powered “biohybrid” robots makes them 11X stronger. Check out this great MIT News feature of our work:

New study in @currentbiology.bsky.social reveals pterosaur brains evolved rapidly at the origin of flight — unlike the gradual reshaping seen in birds.

Most complete lagerpetid brain cast shows side‑placed optic lobes like pterosaurs and bird precursors 🧠

Neuroanatomical convergence between pterosaurs and non-avian paravians in the evolution of flight
Bronzati et al. show that pterosaurs, the first flying reptiles, evolved brains resembling bird precursors but not modern birds. They also demonstrate that, unlike birds, which built on inherited dino...
