I WONDER - How Big Were The Carnotaurus' Arms?

The Carnotaurus had notably short and atrophied forelimbs, which were so small they likely served no functional purpose. Each arm was about 25 inches long with two reduced fingers, unable to reach the mouth or grasp prey. These forelimbs are the smallest relative to body size among large theropods.
