They are fighting on a slippery beach, not a very good place to fight... that's a recipe for extinction!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
This I don't know... Have to wait for the publication. But if you look closely at the photos released in the press, you'll see the crests in the restored versions of the skeletons...
Wonder if they're fighting over a fishing spot...and would the rocks be slippery underfoot for them?
