Near water, perhaps. IN is less likely, overall.
Most ankylosaurs do not have a hippo-like rib-cage, which is de minimis
for considering the possibility of a semi-aquatic lifestyle. (Note,
based on Greg Paul's recent reconstructions, *some* ankylosaurs may
well have been hippo-like in chest proportions).

Which is also fairly reasonable.
The armor may well have protected the animal from dissociation until
the armor fell off.
The peace of God be with you.
