There's one mammal or near-mammal Lower Jurassic ichnogenus from Brazil,
if I remember correctly, but I've forgotten the name!
South Africa's Elliot Formation has an ichnogenus called /Ameghinichnus/.
That one's been accused of having been made by a non-mammalian
tritylodontid.
I think that Arizona's Kayenta Formation manages possible trity burrows
but again, neither my memory or my conveniently available notes can
confirm that.

I wonder how new this news is. On one of the Discovery Channel series,
may not be the one about dinosaurs and could be the one about
protomammals that is part of a miniseries, it discusses tiny mammal-like
reptiles who burrowed far beneath the surface to where there were roots
and other moisture, and they survived the terrible long drought that
killed most of the larger and more advanced animals that lived on the
surface. It sounded as if they knew what and where these creatures were,
and how they lived.
