A small bone or projection at the tip of the coracoid bone, which is part of the shoulder skeleton in some animals.
From Greek 'akron' (peak, tip) + 'korakoeides' (raven-like, referring to the coracoid bone's shape). The coracoid was named for its resemblance to a raven's beak. The prefix 'acro-' indicates this is a terminal or tip-like version of the structure.
