This collection of discussions collectively emphasizes the study's conclusion that T. rex's skull was likely non-movable, supported by phrases like 'most supported the findings' and 'skull of tyrannosaurids to be functionally akinetic.' The tone is analytical and supportive, with references to research methods like finite element analysis, which demonstrate deep engagement and recognition of the study's significance in paleontology.
AgreementStrong agreement
Most posters support the findings, emphasizing that the skull of T. rex was most likely rigid, aligning with the article's conclusion of an akinetic skull.

Posts highlight the importance of this research in understanding dinosaur biomechanics, with some saying it clarifies long-standing questions, signaling high-impact implications.
Abstract in brief
The study investigates whether Tyrannosaurus rex had cranial kinesis (movement of skull joints), which is unusual for animals with powerful bites, by testing different palatal postures through biomechanical models.
Researchers used finite element models of T. rex and living animals like parrots and geckos to compare strain patterns in various skull postures, finding that T. rex's skull likely remained rigid and did not exhibit significant movement.
The results suggest that small palatal movements would have caused strains beyond structural limits in T. rex, supporting the idea that its skull was functionally akinetic (rigid) despite previous hypotheses about cranial mobility.]
My paper with Kevin Middleton, @kalebsellers, Scott Echols, @WitmerLab, Julian Davis, and @CrocHolliday is out on AR's website today! I didn't know this was out online, though I've been moving halfway across the country, so, you know, surprise!

Happy #FossilFriday! We're back from a hiatus and featuring new @JurassicFDN-supported research. Tyrannosaurus crunched prey using a stiff rather than flexible skull - read all about it here: https://t.co/9LrpH9eNQd https://t.co/QcGWhxwkrt

Han comparado la mandibula de los Tiranosaurios con la de los loros (y no me sorprende nada, ouch). La conclusión es que no poseían la movilidad que tienen estos, ni la de los gecos tampoco (paper) https://t.co/FYqGWvGDha (blog, abajo) https://t.co/tAeaoexOFk https://t.co/uf1qVR8FLO
