dinosaur man Posted January 12, 2020 Share Posted January 12, 2020 Hi I’m wondering what the Antorbital fossa is for in dinosaurs. I heard it could be part of muscle attachments or nasal passages. If so if a dinosaur has a big Antorbital fossa does it mean they have better nose or stronger jaw muscles. Thank you!! Link to comment Share on other sites More sharing options...

I did read the second one but I am also wondering if a dinosaur has a big Antorbital fossa does it mean they have a better nose or stronger jaw muscles?

Fossildude19 Posted January 12, 2020 Share Posted January 12, 2020 Fossa are grooves, rather than an opening. Many archosaurs had an antorbital fenestra, an opening or hole. It housed the paranasal sinus. Being the largest hole in the skull, it was probably for better smell. And being another hole in the skull, it would make the mandible weaker, I would assume. 2 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."
