Scientists have announced the discovery of a new A. afarensis fossil, and the "big man" seems to have a lot to say. Any post-cranial fossils from any hominid will always be a big deal, because, since our ancestors were mostly hunted by bone-crunching leopards and hyenas, by far the most common fossils we find are skulls (because the head has an annoying tendency to roll away) and the teeth inside them. That the fossil represents an adult male of the same species as the famous Lucy is an added, and valuable, bonus.
