At least the Mongolian Late Cretaceous ankylosaurs, as Talalurus,
Saichania, Pinacosaurus (...) were living in a pretty arid
environment; some of their fossilized remains suggest the animals
were killed in a sandstorm or by a moving sand dune, e.g. an
aggregation of juvenile Pinacosaurus.
Talking about insectivorous habits, I think Perle proposed the theory
that Therizinosaurs made a living of termites; the huge claws being
used to rip open termite hills.
As Jonathan stated, these animals all were large to huge;
present day insectivores tend to be small (except of the armadillo's
and anteaters which are medium sized, but nothing compared with
large mammalian herbivores), instead of ponderous and barrel-shaped
like ankylosaurs were.
