Accompanying our recent paper documenting evolutionary changes in jaw muscles along the line to birds, is a collection of models on Sketchfab illustrating 3D resultant vectors of jaw muscles along with skulls and a few different ways of visualizing data like these. (www.pnas.org/doi/10.1073/...

Dinosaur Jaw Muscle Evolution - A 3D model collection by Holliday Lab (@holliday)

This collection shares 3D models of skulls and jaw muscle resultant vectors demonstrating phylogenetic changes in muscle orientation along the lines to modern birds. While temporal muscles shifted to ...

Happy to share this new paper! We explored the relationships of head shape and feeding mechanics in dinosaurs. A cascade of changes from big brains, to reoriented muscles, to a breakdown of linkages resulted in avian powered kinesis, but not until neognathes. www.pnas.org/doi/10.1073/...

Got to see the latest Squirrel-raptor at The Field Museum. Its exquisite preparation was done by Connie Van Beek and Akiko Shinya. Here’s Connie working on a more recent bird from the Green River Fm., a similar type of slab fossil, just ~90degrees of Eocene longitude away and ~90million yrs later.

Got to visit the Field Museum Friday. Got my picture with Geology Collections Manager Bill Simpson. Bill helped get me started in this grand adventure in Paleo. I’m forever grateful to him and all the rest of the Sue prep team, who still let me hang in the lab when I show up with my own students.

I am very proud of the work that went into this new Sanger Lab publication. This paper was led by postdoc Marta Marchini and a number of my lab's undergraduate students, each of which contributed unique skills or effort to the completion of this project.

Big week coming up at the 2024 Anatomy Connected meeting in Toronto starting this weekend. Come catch a bunch of talks and posters from the lab as well as our symposium on Visualizing the Scale of Skeletal Muscles.
