Maybe it's really simple... I just don't know the answer (my 9yr old asked and I couldn't give a straight answer - she can tell when I don't really know so I need my credibility back).

This is my take on this:
If dinos want to bounce between the bottom and surface twice a day they must make sure they can control their buoyancy.
A bubble is a fast trip to the surface and that can be a very long one for such a small animal.
