Four gibbon crania viewed from the right side, so they are facing toward the right of the image. Bones and teeth are semitransparent white-yellow, while endocranial (e.g. brain) surfaces are solid blue. They are in left-right order from infant to adult, showing how the teeth form and emerge and the cranium changes size and shape.
My first gibbon paper is out! In collaboration with @evodevoanthro.bsky.social, we examined tooth formation and emergence in a unique skeletal collection, showing how gibbons' giant canines affect development of other teeth in the jaw onlinelibrary.wiley.com/doi/10.1002/...
