Can anyone point me to an illustration of the range of motion for Maiasaura's tail?

Also an illustration of Maisaura laying an egg would be great.  I imagine she would be on all fours, squatting down but how far would she squat?  Here's an animatronic Maia laying an egg...kinda fun but i imagine she'd squat down further at the rear, so the egg doesn't have so far to drop.

I don't have an illustration but I can say that since Maiasaura is a hadrosaur, the tail would be very stiff and rigid until about halfway down. The tail and back were stiffened by ossified tendons so it can be expected that the base of the tail likely doesn't have much dorsal flexibility but would have a little lateral flexibility.
