Ahoy there Skullywags! In the latest episode of Skullywag Chats, I team up with @NarimaneChatar from @UCBerkeley to discuss an evolutionary pattern she and her team discovered in the molars of meat-munching mammals #skull #science #💀 youtu.be/6TmKAKhag7w?si=td2n… via @YouTube

So happy to have been invited by @DRexMitchell for this little chat about our recent tooth paper in @ScienceMagazine (doi.org/10.1126/science.aee3…) for his YouTube channel, The Skullywag Lab, check it out 🤩: youtube.com/watch?v=6TmKAKha… #SciComm #ScienceCommunication #AcademicChatter

Performance trade-offs define a fundamental dental dichotomy in mammals

Teeth define mammalian evolution, and one of many adaptive dental breakthroughs in crown mammals is the tribosphenic molar: a tooth with a dual shearing-crushing function, often considered a key...

A new model of skull function just dropped! It describes the skull as an arch-bridge like structure that uses tensile elements to guide arcs of compressive stress between the biting teeth and jaw joints. Written by me! 💀💀💀 #skull #science onlinelibrary.wiley.com/shar…

Our lab just published a cool paper on seed-cracking bettongs. Not just any seeds, but some of the hardest seeds out there! Two species in the same genus showing different adaptatiosn to hard biting. Very cool 💀💀🤓🤓 #skull #science academic.oup.com/zoolinnean/…

This was a fun little side project I worked on while doing placoderm biomechanics analysis with the Flinders Gogo team. To be presented at @CAVEPS_Palaeo 💀🤓 #Devonian #fossil #placoderm #paleontology youtube.com/shorts/0NByEKZbL…

I only played a very small role in this @PNASNews article by @AbbyGraceDrake, @JLosos, et al., but it's cool, so please check it out! "Copy-cat evolution: Divergence and convergence within and between cat and dog breeds." doi.org/10.1073/pnas.2413780…

What if the Rancor in @starwars was a domesticated breed similar to a pug or a bulldog? In the latest video from The Skullywag Lab, I "un-pug" the Rancor to see what a wild, undomesticated Rancor ancestor might look like! #skull #science #starwars youtu.be/di40LOfgSoA?si=Ghlz…
