Subject: Ankylosaurid tails?

Just a question - were ankylosaurids able to swing their tails to the
side and upwards, or only sideways. And how quick movement it would be?

It could be a clue to their function - sideways swinging can be used
both against predator and conspecifics, but swinging upwards is good
indication that tails were employed against predatory dinosaurus.
