La investigación de universidades británicas señala que la disminución de las extremidades anteriores ocurrió en paralelo al fortalecimiento del cráneo

Los expertos descubrieron que los brazos pequeños no eran simplemente un subproducto del aumento de tamaño del cuerpo.

Universidades de Reino Unido analizaron varios datos de 82 especies de terópodos. La forma de los brazos tendría relación con la dimensión de los cráneos de estos dinosaurios

Un estudio de las universidades de Cambridge y London sugiere que los brazos cortos del T. rex evolucionaron debido al poder de su cráneo y mandíbula.

You probably wouldn't say it to its face, but the famously fearsome Tyrannosaurus rex has long been the butt of tiny arm jokes.
