How Small Are T Rex Arms
T Rex arms are short relative to its massive body. Adults had forelimbs roughly 3 feet long, with only two functional fingers. Despite their size, the bones were thick and heavily built.
How Strong Were T Rex Arms
Studies suggest T Rex arms could lift hundreds of pounds. Muscle attachment points on the bones indicate powerful flexors and adductors. The arms likely helped grip prey during bites.
What Role Did T Rex Arms Play
Scientists believe T Rex arms assisted in holding prey steady while the jaws delivered the killing bite. The short reach may have also helped the dinosaur pull objects closer. For more details on T Rex anatomy, see research from the Natural History Museum.
